Hot Starff, a six-year-old mare, led for the last lap before holding off a brave Key Reactor by half a neck.
The time for the 1609 metres was 2:00.7 with the last 400 in 27.9.
Hot Starff has now won five races and more than $40,000 in stakes.
Bred and raced by D. J. and Mrs E. G. Luke, the mare is out of the winning Sands A Flyin mare Nor West Star, and is her first foal.
