Amber Mariano

As a member of the jury, she cast her vote for Donaldson, who lost to Tina Wesson in a 4–3 vote.

After the merge, van den Berghe was voted out despite Mariano promising to take care of him. Mariano and Brkich also managed to maintain several "alliances," including their agreement with Boneham and Lewis, one with "Big Tom" Buchanan, and one with Calaway. Eventually, the pair ended up in the Final Four with Lewis and Boneham. Once there, Brkich won her first individual Immunity challenge, and she and Mariano convinced Lewis to vote out Boneham instead of forcing a tie. In the final three, Mariano won immunity and chose Brkich to continue with him to the Final Two. Facing the jury, they both met criticism for their gameplay. Ultimately, Brkich was victorious by becoming the Sole Survivor in a 4–3 vote, securing her the winner by receiving votes from van den Berghe, Calaway, Huang, and Buchanan while Mariano received votes from Vavrick-O'Brien, Boneham and Lewis. Before the vote was read, Mariano proposed to Brkich, which she accepted without hesitation.

Mariano and Brkich ultimately finished in second place behind married couple Uchenna and Joyce. Amongst fans, there has been much speculation surrounding the final leg of the race. It has been argued that the production crew had intervened with the airport authorities and aided Uchenna and Joyce onto the same earlier plane as Mariano and Brkich. In the "Revisiting the Race" special feature on the Season 7 DVD, Mariano, along with Uchenna and Keoghan denied these accusations. Mariano describes Uchenna running around frantically trying to get onto the flight, which the final edited version of the show does not portray. Keoghan cites the fact that the decision to re-open the door rested solely with the pilot, and that intervention by the production crew would have resulted in someone leaking such information out. Although Mariano and Brkich lost the one million dollar grand prize and "The Amazing Race 7" winners' title at the final leg of the race, they managed to place 1st in the 2nd, 4th, 7th and 10th legs. They were the only team to not come in last place on any legs of the race.

In 2007, the Marianos competed on the All-Stars season of The Amazing Race as newlyweds. After achieving first place for the first three legs, they came in last and were eliminated in the season's fourth episode which aired on March 11, 2007.

In 2006, the Marianos filmed a ten-episode show for the Fox Reality Channel, Rob and Amber: Against the Odds, which aired in 2007. Set in Las Vegas, the show follows Rob's attempt to become a professional poker player and features professional player Daniel Negreanu tutoring him.

She began a relationship with fellow reality star Rob Mariano in 2003, when they formed an alliance as castmates on Survivor: All-Stars. They became engaged on May 9, 2004, during the show's live finale at Madison Square Garden in New York City, and married on April 16, 2005 at Atlantis Paradise Island in The Bahamas. CBS aired a two-hour special about the wedding, entitled Rob and Amber Get Married, on May 24, 2005. After their marriage, the couple moved to Pensacola, Florida. They have four daughters: Lucia Rose (born July 4, 2009), Carina Rose (born December 10, 2010), Isabetta Rose (born May 5, 2012), and Adelina Rose (born June 20, 2014). Their family are members of the Catholic Church.

Immediately following her appearance on Survivor: The Australian Outback, Brkich appeared on the cover of Stuff magazine. Maxim ranked her as the 50th most beautiful woman in the world in 2004 and 73rd in 2005. She also appeared in various commercials for Adelphia Cable, Rite Aid drugstores, and Mountaineer Racetrack in West Virginia.
