The 2013 event ended the two-year run of poor entry numbers, with a record field of over 50 cars. Another first for the event saw the opening round of the 2013 Australian GT Championship incorporated into the first hour of the race. The results of the GT Championship round were based on the positions of the cars that had elected to race for GT Championship points at the end of the first hour of racing. Teams could then either continue on and complete the full race, or withdraw their car after the first hour. Drivers were allowed to cross-enter between cars so that they could race one car in the one-hour GT Championship race and then drive another car that was entered for the full 12 hours. Erebus Motorsport took the first win for an Australian team under the GT regulations with German drivers Bernd Schneider, Thomas Jäger and Alexander Roloff taking their Mercedes-Benz SLS AMG to victory.
