The Troy star was competing in the Targa Tasmania rally when he miscalculated a tight bend, sending him colliding into trees in his restored 1973 Ford XB Coupe, which was badly damaged by the accident.
He says, "We had been having a great day until then... But I misjudged a tight left-hander and we went in a little too fast - the car understeered off the road and got onto the gravel and we went into a couple of trees at a fairly low speed.
"The car is a little battered on the driver's side which is a real shame, as many hours had been spent reshaping its original panels to get it just right. It's a real shame, but that's motor racing."
Bana's co-driver Tony Ramunno also emerged uninjured.
