A mid-season draft selection by Greater Western Sydney in 2021, Peatling became a regular in the Giants' 2024 side and played both their qualifying and semi-finals before Adelaide traded for him that off-season, sending a future second-rounder north and receiving the Giants' future third and fourth in return. The 186cm clearance midfielder laid 10 or more tackles in four games that season. He has played 89 games and kicked 32 goals.
