 On lap 70 Garth Tander was assigned a mechanical black flag, it was assumed for a fuel leak, but as it transpired to be a leak from Tander's drink bottle the flag was withdrawn.Subsequently, Tander's car shed a headlight cluster into the path of pursuing cars to no penalty, causing controversy amongst team principals and officials in the pits.Courtney took the lead from Tander just prior to a safety car being called for Andrew Thompson, parked in the first chicane.
