James Hird's car has been stolen after intruders broke into his Toorak home, in Melbourne's south-east, overnight.
Police say the robbery took place between midnight and 1:30am while the former Essendon coach and his family were at home, but they were not hurt.
A silver Audi Q7 station wagon, registration XCA-676, was stolen.
Police also believe electronics were taken from the home.
"Stonnington Crime Investigation Unit detectives are investigating the circumstances surrounding an aggravated burglary in Toorak overnight," a Victoria Police statement said.
"The occupants, who were home at the time, were not disturbed during the incident."
The former Brownlow medallist was a central figure in the Essendon Football Club's supplements saga that engulfed the team from 2013.
Anyone with any information about the robbery is urged to contact Crime Stoppers.
