Chad Cornes

On 21 September 2015, Cornes was announced as the SANFL coach of the Port Adelaide Football Club. He was elevated to a forward development coach with the Power at the end of 2017.

Cornes came out of retirement, and was traded to the Giants during the 2011 October Trade Week. He was a playing assistant coach. On 3 July 2013 Cornes retired from AFL football.

Post retirement, Chad Cornes remained with GWS in a full-time coaching role with their backlines, a position he held from 2013 to 2015.

Despite having to stay on the sidelines for the rest of the year, he played on in 2011. In August 2011 he announced that he would be retiring from the AFL after the following week's match against Collingwood.

Port looked to bounce back from their Grand Final humiliation of the previous year when they took on Geelong in the opening round of 2008. Despite being close throughout the match, they were unable to win and that was the start of a four-game losing streak for the Power. Cornes suffered a broken finger in Round 6 against St Kilda but returned just three weeks later despite the nature of the break being very severe. After 2 years with on and off form, Cornes broke his finger again in mid-2010.

In 2007, Cornes was a key midfielder and has a largely impressive season. Cornes finished the 2007 season with 643 disposals, and led the competition in kicks, and went into the Brownlow medal count as one of the favourites. The great form of Cornes in midfield was crucial to the side making the AFL Grand Final, which was a huge surprise to most, including Cornes. Despite not expecting to have a good season, when they did make the Grand Final the belief appeared to be strong but they were unable to win their second flag, going down to Geelong by a record 119 points

The 2006 was a disappointing one for Port Adelaide, and one which frustrated Cornes in particular. The season never really took off, and with Cornes now being a senior player, he was moved into the midfield to help the younger players. This move paid off as he dominated matches, which was a huge positive for the Power in an otherwise disappointing campaign. Cornes won the Showdown Medal in round 21.

In 2004, Cornes was moved to centre-half back. The new position worked wonders as Cornes began to single-handedly dominate games, earning himself his first All-Australian award, and finishing third in the Brownlow medal. The move to centre-half back was a key reason for Port Adelaide's dominance, which culminated in their first Premiership in 2004, defeating the Brisbane Lions by 40 points. He had a key defensive role on Brisbane Lions' forward Jonathan Brown during the Grand Final, restricting him to just one behind for the match.

After Port Adelaide's dominance in 2004, Cornes was again used as a key defender to great effect. However, Port Adelaide was unable to repeat its finals' glory of 2004, being eliminated by cross town rivals Adelaide in the first semi-final.

Cornes began his AFL career as a key-forward and after playing only 6 games in 1999, was a regular in the Power forward line in 2000, booting 22 goals. Between 2000 and 2003 Cornes and Tredrea formed one of the best forward partnerships in the AFL, with Chad playing up the ground demonstrating his great contested marking ability. Despite being one of the best forwards in the game, Cornes was moved into defence at the start of the 2004 season.

Chad Studley Cornes (born 12 November 1979) is a former professional Australian rules footballer who played for the Port Adelaide Football Club and Greater Western Sydney Giants in the Australian Football League (AFL). He was a member of the Port Adelaide side which won the premiership in 2004. On 3 July 2013, he retired from AFL football due to a troublesome knee. Cornes is currently serving as a forward development coach for the Port Adelaide Football Club.

In addition to his brother Kane Cornes, his father, Graham Cornes, is also a former VFL/SANFL footballer, playing 317 games for Glenelg with a career spanning from 1967 to 1982. Graham also coached various AFL/SANFL teams between 1983 and 1994. His stepmother Nicole Cornes was a 2007 Labor candidate. He has three younger half-sisters paternally.
