He was St Kilda's leading goalkicker in 2002, kicking 50 goals from 21 matches in the 2002 AFL Premiership Season.

[4] Milne played his 100th AFL game in round three, 2006, against the Brisbane Lions, kicking three goals as the Saints won by 37 points.

He was driven back from Perth with St Kilda medical staff to avoid the risk of further damage and arrived in Melbourne on the Thursday following the game.

Milne played in 20 of 22 matches in the 2009 home and away rounds in which St Kilda qualified in first position for the 2009 AFL Finals Series, winning the club's third minor premiership.

[17][18] Under coach Ross Lyon, he has continued to develop his forward defensive skills and setting up play in addition to his ability to score goals.

Milne played in the drawn 2010 AFL Grand Final, in which he kicked two of St Kilda ten goals for the game against Collingwood.

He was involved in the game's pivotal moment: St Kilda was trailing by one point with 90 seconds remaining, a 60m running shot by Lenny Hayes (St Kilda) landed 10m in front of the right behind post and in the vicinity of Milne and his opponent; the ball took one bounce 45° left toward the goal, then another bounce 90° right and went through for the tying behind, eluding Milne's efforts to gather the unpredictable ball.

He was St Kilda's leading goalkicker in 2010 with 55 goals for the season prior to the 2010 AFL Grand Final Replay.

In St Kilda's Round 21 home game against the Magpies, Milne became the first player in the history of the league to kick 300 goals at Docklands Stadium.

[23] Milne finished the 2012 season with 56 goals from 22 games, and was selected in the 2012 All-Australian team, earning this recognition for the second time in his career.

In 2016, Milne joined amateur football for Beaumaris in the VAFA Premier B, where he played in a senior team premiership, defeating St Bedes at Trevor Barker Oval in Sandringham.

The incident is alleged to have taken place on 14 March 2004 at teammate Leigh Montagna's home after celebrations for St Kilda's family day.

An investigation by the Sexual Crimes Squad of the Victorian Police force followed, which was led by Senior Detective Scott Gladman.

Magistrate Peter Reardon found there was enough evidence to send the matter to the County Court for trial.

Milne pleaded guilty earlier this month to a single charge of indecent assault, over an incident at the home of former St Kilda teammate Leigh Montagna in March 2004.
