Erin Phillips

For the 2020 season, the league expanded to 14 teams and the season was extended to eight games. An additional round of finals was added, allowing three of the seven teams from each conference and six in total to make the finals. Phillips was not ready to return from her ACL injury until Round 4. In her return, Adelaide lost to Carlton in a rematch of the previous year's grand final. Phillips had 13 disposals in the loss. After missing Round 5 due to soreness resulting from not playing for 11 months, Phillips played one more game the following week. After Round 6, the AFLW cancelled the remainder of the home-and-away season in favour of starting the finals early due to the global COVID-19 pandemic. Even though the finals were also expanded from six to eight teams, Adelaide did not qualify with just two wins in their first six matches. Ultimately, the finals series was cancelled due to the pandemic after only the first round was played.

As a result, Phillips instead ended up signing with the Adelaide Football Club as a rookie, a spot reserved for footballers coming from other sports. She had previously stated it was "highly unlikely" that she would join Adelaide in the event that Port Adelaide did not get a license. Phillips later reneged, saying, "When the Adelaide Crows contacted me I was just so blown away how professional they were and how committed they were, not only just in getting me to play but how committed they were to the women’s game itself. They want to be the club of choice to not just young girls but young women to aspire to, whether they want to play football or whether they want to be a coach or work in administration." She also commented that she thought "[her] time had passed at playing football" when Port Adelaide did not pursue a licence.

With the expansion of the AFLW to 10 teams for the 2019 season, the league was restructured into two conferences. The number of home-and-away games was kept at seven, and the finals system was expanded to include one pair of preliminary finals before the grand final. Adelaide opened the season with a one-point loss to Western, the reigning premiers, largely as a result of kicking an inaccurate 1.11 (17). Despite the loss, Phillips earned two votes with 18 disposals and two behinds. From the next game on, Phillips and the Adelaide Crows dominated the rest of the season. They did not lose another game, and Phillips received three votes for best on ground in five of the six remaining games. After their 13-point Round 2 win against Carlton, Adelaide won each of their last five home-and-away games by at least 29 points. They won the minor premiership after finishing tied with Fremantle with six wins, but had a markedly better percentage in part due to defeating them by 42 points in Round 4 in Fremantle's only loss. Phillips had a season-high 25 disposals as well as two goals in that win against Fremantle. She kicked a season-high three goals one week earlier against Geelong.

Adelaide continued their dominance into the finals, winning their preliminary final against Geelong by a season-high margin of 66 points and keeping their opponents scoreless through three-quarter time. They held Geelong to just seven points, the lowest score in AFLW history. Phillips had 23 disposals in the game, trailing only her teammate Ebony Marinoff who had 27. Adelaide faced Carlton in the 2019 AFL Women's Grand Final. In front of 53,034 fans, a record for a standalone women's sporting event in Australia, Adelaide won convincingly by a score of 10.3 (63) to 2.6 (18). Despite not playing the final quarter after tearing the ACL in her left knee late in the third quarter, Phillips was named AFLW Grand Final best on ground for the second time. She had 18 disposals and kicked two goals before leaving the game. She received a standing ovation when she was taken off the field on a stretcher. At the end of the season, Phillips won her second AFLW best and fairest award. She accumulated 19 out of 21 possible votes from her seven matches, and finished eight votes ahead of Fremantle's Dana Hooker. Like in 2017, she was the third-leading goalkicker in the AFLW, this time behind teammates Stevie-Lee Thompson and Danielle Ponter. Phillips made the All-Australian team for the second time, and was also named captain of the team. She again won the AFLW Players’ Most Valuable Player Award.

Phillips struggled with a right quad injury through much of the 2018 AFL Women's season. She first injured the quad in the preseason and then aggravated it the day before the start of the season, keeping her out for the first two games. Adelaide lost both of the those games without Phillips, which were against Brisbane and Melbourne. When Phillips returned, Adelaide resumed winning as Phillips starred with four of Adelaide's six goals and two of their five behinds, earning best on ground. However, this turned out to be the only game of the year where Phillips earned any votes. After a draw against Greater Western Sydney in heavy rain, Adelaide won their next two games in Round 5 and Round 6. Phillips's quad injury forced her to miss the second half of the Round 5 win. She recovered to kick three goals the following week. Just like in 2017, Adelaide entered their Round 7 game against Collingwood needing a win to make the AFLW Grand Final. This time, however, Adelaide squandered a 17-point lead in the second quarter and lost the game after co-captain defender Chelsea Randall missed the second half due to a concussion.

With the launch of the AFLW in 2017, Phillips began her football career at age 31 as a co-captain of Adelaide. Despite not having played competitive football in nearly 18 years, she quickly emerged as the league's best player and one of its biggest stars. She won the AFLW best and fairest award by a wide margin in both 2017 and 2019, as well as the AFLW Grand Final best on ground as a member of Adelaide's premiership teams in both years. Phillips plays as a midfielder and is also one of the leading goal scorers in the competition.

Following her release by the Dallas Wings and retirement from the WNBA immediately before the start of the 2017 WNBA season, Phillips was named the Wings' director of player and franchise development a week later. Shortly after the end of the season, Phillips was promoted to assistant coach of the team for 2018, replacing Bridget Pettis. She coached alongside fellow assistant coach Taj McWilliams-Franklin and under head coach Fred Williams, who had been the team's head coach in Phillips's last year as a player in the WNBA as well. She retained her position the following year as the Wings hired new head coach Brian Agler. She had turned down the opportunity to interview for that head coaching vacancy in order to return to Australian rules football in the AFLW during the offseason. Phillips left the coaching staff following the 2019 WNBA season in search of opportunities in Australia.

With the AFL planning to launch a national Australian rules football women's competition in 2017, Phillips agreed to become a marquee signing for the Port Adelaide Football Club, her father's club in the SANFL, on the condition that they receive a license for the inaugural AFL Women's (AFLW) season. By March 2016, however, Port Adelaide decided not to bid for a license for 2017 in order to focus on their plan to play the first AFL game in China that same year.

Phillips was named as a co-captain of Adelaide for the inaugural 2017 AFL Women's season, along with Chelsea Randall, one of the club's marquee signings. Although Phillips received approval from the Dallas Wings to play in the AFLW during the WNBA offseason, medical insurance on her WNBA contract did not cover any injuries from playing Australian rules football. Despite the possibility of an injury voiding her WNBA contract or the fact that her salary was about ten times higher in the WNBA compared to the AFLW, Phillips decided to play in the league at her own risk.

The 2017 AFLW competition consisted of eight teams playing a home-and-away schedule of seven games, one against each of the other teams. At the end of the season, the top two teams in the ladder would contest the Grand Final. Adelaide had a strong start to the season, winning their first two games with the largest margin of victory in each week. Phillips was awarded best on ground in both games, receiving the maximum three votes that were to be tallied at the end of the season to decide the competition's best and fairest. She led the Crows in goals in the first game of the season with three. Although Adelaide trailed at three-quarter time against Carlton in Round 3, Phillips led her team to victory with the only goal of the final term, which she kicked from a long distance of 60 metres. Phillips was awarded best on ground for the third and final time during the home-and-away season in Adelaide's Round 4 win, leading the Crows with 18 disposals.

The 2017 AFL Women's Grand Final was a rematch of Adelaide's Round 5 loss to Brisbane, who won the right to host the match as minor premiers. Adelaide won the inaugural AFLW Grand Final by a score of 4.11 (35) to 4.5 (29), never trailing in the match. Phillips won the AFLW Grand Final best on ground, having recorded 28 disposals, 7 marks, and 7 tackles, all personal season-bests and team-highs in the game. She also kicked both of Adelaide's goals in the second half. Phillips ended the year as the third-leading goalkicker in the AFLW with ten goals. At the AFLW Awards, Phillips was named the inaugural AFLW best and fairest, finishing the season with 14 votes, four ahead of the Western Bulldogs' Ellie Blackburn and Melbourne's Karen Paxman. Her match-winner from Round 3 against Carlton was also named the AFLW Goal of the Year. Her on-the-shoulders mark against Melbourne was a finalist for AFLW Mark of the Year, which she lost to Darcy Vescio. Phillips also won the AFLW Players’ Most Valuable Player Award.

Phillips plays primarily as a midfielder who is also a goal-scoring threat like a forward. She excels at being able to read plays in order to capitalize on opportunities, such as creating set shots for her teammates off of free kicks. Phillips is capable of kicking goals in a variety of ways. She can kick from long distances such as her 60-metre AFLW Goal of the Year in 2017, or from sharp angles in the pocket. Although Phillips isn't one of the bigger players in the competition, she is tough and physical, skills that are useful for taking marks either in the air or after bodying off defenders to establish positioning. She is not considered one of the faster players in the league due to being one of the older players in the competition.

Phillips was one of many female athletes in Australia who advocated for the legalisation of same-sex marriage in the lead-up to the nationwide marriage law postal survey in late 2017. The positive support found in the survey led to its legalisation before the end of that year. While Phillips doesn't see herself as a leading advocate for LGBT rights, she has presented her marriage openly and wants to be seen as a role model to others in this respect, in particular to young girls and both male and female athletes.

The last major international tournament of Phillips's career was the 2016 Summer Olympics in Rio de Janeiro. Phillips and Laura Hodges were voted co-vice captains by their teammates, while Penny Taylor was voted captain. Despite sweeping their round robin group, Australia were upset in the quarterfinals 73–71 by Serbia in a game where the Opals had 26 turnovers. Phillips had 10 points and 4 assists in the loss. Overall, she averaged 4.7 points, 3.2 assists, and 2.0 rebounds in 23.5 minutes per game while playing as a starter. The loss to Serbia ended the Opals' streak of five consecutive Olympics with a medal. Phillips officially retired from competitive basketball in January 2018.

Seven years later, Phillips planned to return to the WNBL for the 2015–16 season. After originally wanting to return to the Adelaide Lightning, she became the first player to sign with the South East Queensland Stars, a new WNBL franchise. However, Phillips never played for the team due to injury and the franchise dissolved at the end of their first season due to financial difficulties. Phillips ranks in the top ten all-time for the Adelaide Lightning in points, assists, rebounds, and steals as of 2019. She is tenth in points with 1498, sixth in assists with 423, seventh in rebounds with 731, and ninth in steals with 139.

Phillips signed with the Los Angeles Sparks in the offseason. She only played 12 games during the 2015 season due to knee issues both early and late in the season. She finished the year with a career-low 26.7% three-point field goal percentage. Phillips missed the playoffs, where the fourth-seeded Sparks were eliminated in the first round by the Minnesota Lynx. During the offseason, Phillips was traded to the Dallas Wings for Riquna Williams and the sixth overall pick in the 2016 WNBA Draft. She was named a co-captain of the new team, which had just relocated and was known as the Tulsa Shock in previous years. Phillips also ended up scoring the first points in Dallas Wings' history. She began the season as a starter before settling into a bench role for much of the rest of the season, only averaging 14.6 minutes per game, the second-lowest of her WNBA career. The Wings finished the season with an 11–23 record and did not make the playoffs. A week before the start of the 2017 season, the Wings waived Phillips. She retired from the WNBA several days later.

Two months before the start of the 2014 season, Phillips was traded to the Phoenix Mercury with a second-round draft pick in return for forward Lynetta Kizer and a first-round draft pick. She joined two of her compatriots on the team, fellow guard Penny Taylor and new coach Sandy Brondello. Led by a five-time WNBA scoring champion in Diana Taurasi and a perennial league leader in blocks in Brittney Griner, the Mercury finished the season with the best record in the WNBA at 29–5, leading the league in both offensive and defensive rating. Phillips only missed one game during the season. After beginning the year as a starter for the first nine games, she lost her starting role to Taylor. She only started one more game the rest of the season, matching her career-high with 21 points. Phillips led the WNBA in three-point field goal percentage, shooting 44.9%. The Mercury dominated the playoffs, defeating the Los Angeles Sparks, the Minnesota Lynx, and the Chicago Sky to win the WNBA title. The only game they lost in the playoffs was Game 2 of the Conference Finals to the defending champion Lynx. Six of the team's eight playoff wins were by at least 14 points. Phillips's best games in the playoffs were the Game 2 loss in the Conference Finals in which she had 10 points and 4 assists, and Game 2 of the WNBA Finals in which she had 7 points and 3 assists.

Phillips moved to the Slovak Women's Basketball Extraliga for the 2014–15 season, playing for perennial league champions Good Angels Košice. The team won the league title as part of their stretch of 15 consecutive titles from 2004 through 2018. Phillips played seven games in both the Extraliga and the EuroLeague, averaging 7.4 points, 3.4 rebounds, and 3.4 assists per game in the Extraliga, as well as 10.4 points, 3.3 rebounds, and 3.3 assists per game during the EuroLeague season.

Phillips returned to the national team as one of 33 players selected to prepare for the 2014 FIBA World Championship for Women in Turkey. She was named to the team for the World Championship, having won the WNBA Finals just 15 days before the Opals' first game in the tournament. Australia swept their round robin group and won their quarterfinal game against Canada. After a 12-point semifinal loss to the United States, the Opals defeated the hosts Turkey for the bronze medal. Unlike her previous two World Championships where she had little playing time off the bench, Phillips established herself in the team's regular starting lineup, leading the team in minutes per game, and was third in scoring and second in assists. Overall, she averaged 8.7 points, 4.0 assists, and 4.0 rebounds in 26.2 minutes per game. In the loss against the United States, she led the team in scoring with a game-high 19 points and made her only three three-pointers of the tournament on six such shots.

—Phillips reflecting on the unexpected record attendance at the 2019 AFLW Grand Final and the game after tearing her ACL and winning best on ground

Just before the start of the 2013 season in late May, Phillips tore her meniscus in her right knee, an injury that kept her out until early July. She only ended up playing 18 games, starting just six of them. Phillips made a career-high five three-pointers in her first start of the year in mid-August. She finished the season second in the WNBA in three-point field goal percentage, shooting 47.9%. Despite having a losing record, the Fever made the playoffs and swept the top-seeded Chicago Sky in the Conference Semifinals. Their season came to an end when they were swept by the Atlanta Dream in the Conference Finals.

After beginning the 2012 season as a starter, Phillips was moved to the bench after five games, but ended up receiving more playing time coming off the bench. She also started the last three games of the season with January and Shavonte Zellous both missing a week due to concussion-like symptoms. The final two games were two of Phillips's best of the season, as she scored 19 and 21 points. Although both players returned for the playoffs for the second-seeded Fever, Phillips started every game in the playoffs except for the first. She saw an increased role on the team after an ankle injury kept Katie Douglas out of the rest of the playoffs following Game 2 of the Conference Finals. The Fever defeated the Dream in the Conference Semifinals and then Phillips's former team, the Sun, in the Conference Finals, both in three games. In the WNBA Finals, the Fever defeated the defending champion Minnesota Lynx 3–1 for the WNBA title. Phillips scored at least 10 points in all five games Douglas missed, including 15 points in the winner-take-all game of the Conference Semifinals and 18 points and 8 rebounds in the series-clinching Game 4 of the WNBA Finals. Overall in the WNBA Finals, she averaged 13.5 points in 35 minutes per game while compiling a 46.7% three-point field goal percentage. Winning the WNBA title vindicated Phillips, who was left off the 2012 Australian Olympic team roster for choosing to play the entire WNBA season instead of sitting out the first half like some of her compatriots in the league. She also finished the regular season third in the league in three-point field goal percentage, shooting 43.8%.

Although Phillips participated in training camps with the national team in preparation for the 2012 Summer Olympics in London, she was not named to the team. The Australian press and the WNBA regarded her omission as a surprise. Nonetheless, Phillips knew she was hurting her chances of making the team by playing the full WNBA season instead of skipping the first half of the year to keep training with the Opals like Lauren Jackson. She decided to play the full season because she thought it was better preparation and she wanted to honour her contract with the Indiana Fever. The Opals won the bronze medal in London, and Phillips ended up winning her first WNBA title.

Phillips was one of the best three-point shooters in the WNBA during her career, ranking top ten in the league in three-point field goal percentage five times in the eight seasons where she played enough to qualify for the rankings. Her best rankings in three-point field goal percentage came in three consecutive years when she finished third in 2012, second in 2013, and first in 2014. Although she did not lead the league in 2013, her 47.9% three-point field goal percentage that year ranks 13th overall in WNBA history as of 2020. Phillips's career three-point field goal percentage of 38.1% ranks 34th all-time as of 2020. Phillips was also an excellent free-throw shooter. Her 84.4% career free throw percentage ranks 33rd all-time in the WNBA as of 2020.

Prior to the start of the 2011 WNBA season, Phillips and fellow Australian Belinda Snell signed with the Seattle Storm. Less than three months later, however, Phillips was traded to the Indiana Fever in April as part of a three-team deal that sent Katie Smith to the Storm from the Mystics, a trade Smith had requested. The Fever were led by team veteran forward Tamika Catchings as well as Phillips's former Sun teammate Katie Douglas. After beginning the season coming off the bench, Phillips won a starting role following a season-ending injury to point guard Briann January ten games into the season. She started a career-best 22 games that year, and averaged a career-best 8.6 points per game to go along with 2.8 rebounds and 2.4 assists per game. Phillips was also eighth in the league in three-point field goal percentage, shooting 42.6%. She scored a career-high 21 points on two separate occasions, both losses to the Atlanta Dream. The Fever entered the playoffs as the top seed in the Eastern Conference. They defeated the New York Liberty 2–1 in the Conference Semifinals before losing to the Atlanta Dream 2–1 in the Conference Finals. Phillips's best playoff game was the winner-take-all Game 3 of the Conference Semifinals in which she scored 12 points and recorded five steals in the Fever's 10-point victory.

The following offseason, Phillips signed with Wisła Can-Pack Kraków, where she played for the next four seasons. In her first two seasons, she won both the regular season and the league championships. In EuroLeague Women], they were eliminated in the quarterfinals during the 2010–11 season and finished in eighth place during the 2011–12 season. Phillips led the team in scoring in the EuroLeague during her first season in Kraków with 14.9 points per game. She was also named a PLKK All-Star in her first two seasons with Kraków.

After the Connecticut Sun could not trade Phillips for the 2010 WNBA season, she instead trained with the national team, winning exhibition tournaments in Hungary during July and in Spain during September. The 2010 international season culminated with the FIBA World Championship for Women in the Czech Republic. Although Australia's only round robin loss was to the United States, they were defeated in the quarterfinals by the Czech Republic, the tournament hosts. Australia finished in fifth place after winning the 5th-to-8th-place consolation bracket. Phillips had more playing time in the tournament than in the previous World Championship, averaging 4.1 points, 2.7 rebounds, and 1.3 assists in 13.6 minutes per game.

Phillips began the 2009 season as a starter. After starting the first 18 games of the season, Phillips and Amber Holt lost their starting roles to bench players and fellow guards Anete Jēkabsone-Žogota and Tan White. As a starter, she averaged 9.3 points, 3.2 rebounds, and 1.9 assists per game. She finished the season with a low three-point field goal percentage of 29.3%, shooting just 20.9% off the bench. The Sun did not make the playoffs that season due to the tiebreak criteria, despite finishing tied for fourth with the Mystics and Chicago Sky. The Sun attempted to trade Phillips before the start of the 2010 season. She was at risk of losing playing time after the team signed experienced guards Renee Montgomery and Kara Lawson to complement Jēkabsone-Žogota and White. They were unable to find a trade and did not sign her to the team roster. Phillips ultimately did not play the 2010 WNBA season.

Phillips began playing in the Polska Liga Koszykówki Kobiet (PLKK) in the 2009–10 WNBA offseason following her last year with the Connecticut Sun. She joined Lotos Gdynia in her first PLKK season, playing nearly the entire year. In 30 games, she averaged 10.9 points, 5.3 rebounds, and 4.3 assists per game, with a three-point field goal percentage of 44.1%. The team won the league championship after finishing second in the regular season. Gdynia also competed in EuroLeague Women, where Phillips was named an All-Star for the Rest of the World team against Europe.

Phillips's father Greg played professional Australian rules football for Port Adelaide, where he won eight premierships and is a member of the club's Hall of Fame. Phillips only played Australian rules football up until age 13 before switching to basketball because of the lack of professional opportunities for female footballers at the time. She made her debut in the Women's National Basketball League (WNBL) for the Adelaide Lightning, her hometown team, at the age of 17 and was named to the All-WNBL Team three times by the age of 22, finally winning a WNBL championship in 2008 in her last year with the team. Phillips was drafted into the WNBA in 2005 by the Connecticut Sun. With the Indiana Fever, she established herself as a starter and won her first WNBA title in 2012. She won another WNBA title two years later with the Phoenix Mercury. During her basketball career, Phillips played both the point guard and shooting guard positions, excelling at three-point shooting and employing a physical style of play. Following her retirement from the WNBA, she was also an assistant coach for the Dallas Wings, the last team she played for in the league.

Phillips joined Ramat Hasharon in the Israeli Ligat ha'Al following the end of the 2008 WNBA season. This was the first year she did not return to the WNBL in Australia during the offseason. Phillips only played the first half of the season for Ramat Hasharon, averaging 11.6 points, 5.3 assists, and 2.8 rebounds per game in 10 regular season games. In the middle of the season, she injured her right knee during the second quarter of the Israeli Cup final in late December. Although she did not require surgery, Phillips returned to Australia for physical therapy and did not play another game with the team. Ramat Hasharon lost the Israeli Cup final.

The 2007–08 season was Phillips's last that she played in the WNBL. She was not ready to return from her ACL injury at the start of the year and ended up playing only 17 out of 24 games during the regular season. Although Phillips did not make the All-WNBL Team, her teammates Tracy Gahan and Jessica Foley were named to the team as they led Adelaide to a 21–3 record, earning them the minor premiership. Phillips had slight drops in her averages, finishing the year with 14.6 points, 5.4 rebounds, and 3.3 assists per game. After Adelaide lost the semifinal to Sydney Uni, they defeated Dandenong to set up a rematch with Sydney Uni in the WNBL Grand Final. Adelaide won the grand final 92–82 for Phillips's first and only WNBL championship. Phillips scored 16 points in the game, second on her team behind Renae Camino who had 32 and was named Grand Final MVP.

Phillips missed the entire 2007 season while recovering from an ACL injury suffered during the offseason while playing in the WNBL in Australia. She did not return to the WNBA until the second half of the 2008 season after missing the first half of the season to train with the Australian national team for the Olympics, which took place in August in the middle of the WNBA season. Phillips played in eight regular season games, all off the bench. In the last game of the season, she scored 18 points and recorded a career-high eight rebounds. Overall, she shot a career-high field goal percentage of 46.4%. Although the Sun finished second in the Eastern Conference, they were eliminated in the Eastern Conference Semifinals by the third-place New York Liberty, losing the decisive third game of the series at home by four points.

Despite being unable to play for the Opals in 2007 due to an ACL injury, Phillips was assured a place on the national team in their preparation for the 2008 Summer Olympics in Beijing. She returned to play with the national team in April 2008 and missed the first half of the WNBA season to continue training with them up until and through the Olympics in August. In addition to exhibitions against New Zealand, Russia, and Chinese Taipei, Phillips was with the team for the Good Luck Beijing event, a warm-up tournament to help Beijing prepare their operations. Without their full team, Australia only won two out of six games. The Opals regrouped for the Olympics. They swept their round robin group, winning all five of those games by more than 15 points. They then won both their quarterfinal game against the Czech Republic and their semifinal game against China by more than 30 points. Nonetheless, Australia finished as silver medallists after losing the gold medal match to the United States 92–65 in a lopsided game, their third consecutive runner-up finish to the United States at the Olympics.

Phillips continued to be one of the best players in the league through the remainder of her WNBL career. She was named to the All-WNBL Team again in 2006 and 2007. During the 2005–06 season, she averaged 15.7 points, 7.5 rebounds, and 4.9 assists per game. She led the league in assists, and was also fifth in free throw percentage at 80.0%. Adelaide finished in a three-way tie for first with a 14–7 record and entered the finals in the second position based on the tiebreak criteria. They lost both of their finals, which were against the Dandenong Rangers and the Canberra Capitals, the two other teams with the same record as them. The second loss to Canberra, who were led by Lauren Jackson, in the preliminary final again came in overtime and was highlighted by Phillips scoring 23 points. Phillips's 2006–07 season ended early after 17 games when she tore the anterior cruciate ligament (ACL) in her right knee during a collision with Canberra player Tully Bevilaqua. She finished the season with a career-high 16.5 points per game to go along with 7.2 rebounds and 4.9 assists per game. This was the second consecutive season she led the league in assists per game. For the second year in a row, Adelaide lost to Canberra in the preliminary final.

Phillips decided to join the Sun for the 2006 season in spite of national team coach Jan Stirling stating that would hurt her chances of playing in the FIBA World Championship later that year, which was scheduled to begin just a week after the end of the WNBA Finals. Phillips played in all 34 games in her debut season. She was named a starter in the 22nd game of the season after an injury to Nykesha Sales and ended up starting the last 13 games. The Sun won their first eleven games with Phillips as a starter as part of a franchise-record twelve-game win streak. She recorded a season-high six assists in her first game as a starter, and then had season-bests of 19 points and 6 rebounds a few games later. Overall, Phillips averaged 5.4 points and 2.5 assists per game. She was also ninth in the league in free throw shooting percentage at 88.0%. Led by their top scorer Katie Douglas and point guard Lindsay Whalen, the Sun finished the regular season with the best record in the WNBA at 26–8. With Sales back from injury, Phillips returned to the bench for the playoffs, where the Sun swept the Washington Mystics 2–0 in the Eastern Conference Semifinals. However, they were eliminated in the Eastern Conference Finals 2–1 by the Detroit Shock, the eventual champions. Phillips's only start in the playoffs came in the first game of that series, a loss on the road.

Phillips is married to American former basketball player Tracy Gahan. The two of them met when they became teammates on the Adelaide Lightning in the WNBL in 2006, and became a couple the following year. They married in 2014 in the United States before same-sex marriage was legalised in Australia. They have three children: twins Brooklyn and Blake (born 2016), and a second son Drew (born 2019). Phillips and Gahan have split their time between living in Texas and Australia.

The Connecticut Sun of the Women's National Basketball Association (WNBA) selected Phillips in the second round of the 2005 WNBA Draft with the 21st overall pick. She was the only player taken in the draft who did not play college basketball in the United States and one of two international players drafted along with fifth overall pick Sancho Lyttle. She did not play during the 2005 WNBA season, instead choosing to play on tours and in training camps with the national team in Australia to increase her chances of making the team.

Phillips began training with the Australian women's national basketball team, the Opals, in 2005. She chose to participate in training camps and tours with the national team instead of joining the Connecticut Sun in the WNBA, who had drafted her in May of that year. She played several exhibition tournaments in China in July, and then helped the Opals qualify for the following year's World Championships in August with their victory in the Oceania Qualifying Series against the hosts New Zealand in August. Phillips's first major senior international tournament was the Commonwealth Games in March 2006, which were hosted by Melbourne and were including basketball for the first time. At home in Australia, the Opals won the gold medal in the women's basketball event, defeating New Zealand in the final by a lopsided margin. Phillips played an important role in the semifinal win against England. The following month, the national team hosted the Opals World Challenge in Canberra, where they defeated the United States women's national basketball team, who had not lost a game in seven years, for the first time since 1998.

Phillips was the Adelaide Lightning's WNBL Ambassador during the 2005–06 season as part of a program to promote the league's athletes as role models. She has also served as a club ambassador for the Port Adelaide Football Club, and has participated in their Community Youth program to educate grade school students on physical and mental health.

Phillips had not played in a football match since participating in the Little Heroes Slowdown in 2004, a charity match featuring retired AFL and SANFL players as well as celebrities. She was named best on ground in that game. Before she returned to training in 2016, the last time she had played football in a competitive league was 17 years earlier at 13 years old.

Phillips made her professional basketball debut with the Adelaide Lightning in the Women's National Basketball League (WNBL) in 2002 at the age of 17. She played six consecutive seasons with the team through 2008. Adelaide made the finals in all six of those years. Phillips had earned an Australian Institute of Sport scholarship to join their WNBL team in 2003, but never played for them after being replaced before the start of that season. Phillips emerged as a breakout star in her third year and was named to the All-WNBL Team (then known as the WNBL All-Star Five) at the end of the 2004–05 season. She averaged 15.0 points, 8.6 rebounds, and 5.3 assists per game that season, and was second in the league in assists behind only her teammate Jennifer Screen who had 5.9 per game. Phillips was also fourth in the league in offensive rebounds with 3.1 per game and fifth in steals with 5.1 per game. Adelaide finished fourth in the ladder and lost their semifinal to the Sydney Uni Flames 94–93 in overtime. Before the game, the Adelaide team had been involved in a car accident that injured some of the players and delayed the start of the game. Phillips had 40 points in the loss. This was the third consecutive year that Sydney eliminated Adelaide in the finals.

Phillips began playing basketball at the age of 13. She decided to switch her sporting focus from football to basketball at the age of 14 due to the lack of opportunities at the time for female footballers to play professionally. Her father had also introduced her to Rachael Sporn, a member of the Australian national basketball team, around this time. As a junior, Phillips played for the West Adelaide Bearcats. She represented South Australia Metro in the under-16 and under-18 Australian national championships, winning the Norma Connolly Trophy as a member of the under-16 championship team in 1999. Phillips was also a member of the South Australia under-20 championship team in 2004, where she won the Bob Staunton Award as the most outstanding player in the women's tournament.

Erin Victoria Phillips (born 19 May 1985) is an Australian former professional basketball player and an Australian rules footballer for Adelaide. She played nine seasons in the Women's National Basketball Association (WNBA) for five different teams and is a two-time WNBA champion. She also represented Australia on the women's national basketball team, winning a gold medal at the 2006 FIBA World Championship for Women and serving as a co-vice captain at the 2016 Summer Olympics. Additionally, Phillips has played four seasons in the AFL Women's (AFLW) competition, in which she is a two-time premiership player and two-time league best and fairest.

Erin Phillips was born on 19 May 1985 in the Carlton suburb of Melbourne to Julie and Greg Phillips. She grew up with her two older sisters Rachel and Amy in Adelaide. Her father was a professional Australian rules football defender who played the majority of his career with the Port Adelaide Football Club in the South Australian National Football League (SANFL), where he served as captain for three years, won eight premierships, and was named to the club's all-time Greatest Team in 2000. He also competed in the Victorian Football League (VFL), which was later renamed as the modern Australian Football League (AFL), as a member of the Collingwood Football Club.
