Assistant coaching (2007–2022) In 2007, Kingsley became an assistant coach at
Port Adelaide, a position in which he stayed in until the end of 2010. He then joined
St Kilda at the end of the 2010 season as an assistant coach, staying at the club until 2018 before joining as an assistant coach in 2019. Kingsley replaced GWS caretaker senior coach
Mark McVeigh, who coached the Giants after
Leon Cameron stepped down in the middle of the 2022 season. His first match in charge, in round one, 2023, saw the Giants come from 31 points down to defeat by 16 points, while losing three players to game-ending injuries, in a match played in 36-degree heat. Despite having a win-loss record of 3-7 after round 10, the Giants won 8 of their last 10 matches to finish seventh and earn Kingsley a finals berth in his first year as coach. The Giants defeated by 24 points in an elimination final at the
Melbourne Cricket Ground, in what was also the club's first final at the ground since the
2019 Grand Final; this was followed by a win over by 23 points at
Adelaide Oval which saw them advance to a preliminary final where they eventually lost to by one point at the MCG. At the end of the season, Kingsley was named coach of the year by the
AFL Coaches Association. ==Media work==
