[1] His older brother, Greg McAdam, had earlier found his way to the St Kilda Football Club via North Adelaide in the SANFL.

In 1986, McAdam played 3 games for Claremont in the West Australian Football League (WAFL) before returning home to Darwin.

He kicked five goals in the famous 1993 game against Collingwood at Victoria Park,[3] after he and Nicky Winmar were racially vilified by Magpies fans while warming up.

[4] In April 2023, the weekend before the 30th anniversary of the game, the Collingwood Football Club formally apologised to Winmar and McAdam for the incident.

He co-hosts the TV program The Marngrook Footy Show with Grant Hansen, currently screening on NITV on Thursday nights.
