A Lamborghini Gallardo with Australian driver David Russell behind the wheel has set the pace during the opening session of practice for Sunday's Liqui-Moly Bathurst 12-Hour endurance race.
Russell lapped the Mt Panorama circuit in 2m 05.92secs, heading a 52-car field by just under half a second from ex-Ferrari F1 driver Mika Salo (Finland) in the Maranello Motorsport Ferrari 458 Italia.
A heavy accident involving the Maranello Ferrari halted the scheduled one-hour session with six minutes remaining.
Experienced V8 Supercar racer Tony D'Alberto was at the wheel of the Ferrari when it collided with the Craft Bamboo Aston Martin Vantage of Frenchman Jean-Marc Merlin.
Both cars sustained heavy damage and D'Alberto is reported to have been transferred to the circuit's medical centre.
