Recall affects more than 6700 vehicles.
Australian Audi A4 owners are being urged to contact their Audi dealerships to check whether their car has a potentially serious air-bag fault.
The ACCC is overseeing the recall announced this morning, a total of 6716 Audi A4 vehicles sold in Australia are involved.
The recall notice warns that the front air-bags may not inflate correctly in the event of an accident. If the air-bag does not deploy correctly there is an increased risk of injury to the front occupants during a collision.
The ACCC says owners should contact their nearest Audi dealer to arrange for inspection and repairs to take place.
