Still developing his ruck craft, Bradtke was limited to scratch matches in the Queensland hub during 2020.
The 204cm ruckman is now into his third full season at the club, after joining the Dees as a Category B rookie in mid-2018.
A talented young basketballer, Bradtke has developed well at reserves level and will benefit from more structured competition with the return of the VFL.
He comes from a rich sporting family with his father Mark a champion basketballer and mother Nicole a star tennis player who won a doubles Olympic Bronze Medal in 1992.
Remains a long-term project for the coaches at Melbourne.
