Feeney made light work of the start from pole, holding the lead into turn 1 before charging into a handy early lead.
His cause was helped by Shane van Gisbergen piling pressure on Andre Heimgartner across the first few laps as they fought over second place.
Heimgartner was resolute in his defence, weathering the initial van Gisbergen storm before the Triple Eight driver backed off and settled into a rhythm right in front of Will Brown, James Golding and Brodie Kostecki.
The gap between Feeney and Heimgartner hung around the one second mark across the first stint, the latter taking his mandatory stop on lap 18.
Feeney responded on the very next lap, retaining the lead but immediately coming under pressure from Heimgartner.
For a couple of laps the Brad Jones Racing driver desperately looked for a way into the effective lead, Feeney defending well as he got his new rubber up to temperature.
He was then able to re-establish a small margin before his teammate came to the rescue for a second time.
Van Gisbergen waited until lap 25 to take is stop, re-emerging right on Heimgartner's tail. That forced Heimgartner to revert to defence and allow Feeney to skip away at the front.
