Saab Australia's local operations will close after the company was unable to find a buyer.
Saab Australia had unsuccessfully tried to sell to a third party in Sweden.
It comes after an attempted restructuring and eventual bankruptcy of SAAB Australia's Swedish parent entity in December 2011.
"SAAB drivers can be confident their vehicles will be kept on the road and they should have no problems accessing parts over the short to medium term," Mr McCallum said.
The administrators will focus on selling the remaining vehicles and significant inventory of parts.
