Harrison Jones claimed the round victory Australian Formula 3 Premier Series at Round 3 of the Australian Motor Racing Series at Morgan Park.
After winning Race 1 from pole on Saturday, Jones backed up his result by standing on the top step of the podium in Race 2 ahead of title rival Cameron Shields.
Shields, however, returned favour in the third and final race of the weekend, leading off the line to take the chequered flag at the end of the 15 lap encounter in wet conditions.
Richard Peasey was second in Race 1 before finishing third in the remaining races.
Jake Camilleri converted his pole position into a pair of race victories in GT-1.
The MARC II Mustang driver overcame a longer compulsory pit-stop time to win Race 1 ahead of Rod Salmon aboard his Audi R8 LMS Ultra.
A mechanical issue in Race 2 for Salmon handed fellow Audi R8 driver Matt Stoupas second spot from Geoff Taunton in third.
Race 2 was marred by a significant incident between Adam Hargraves and Jason Busk, with the MARC I drivers coming to blows at Turn 4.
James Burge won the opening two races of the weekend in the Legend Cars before retiring in Race 3, breaking a 12 race long winning streak.
Burge headed home Ben Jagger in Saturday’s pair of races, but a broken axle forced the former out of contention in the reverse grid Race 3, with Zane Morse picking up the pieces to cross the line first from Jagger.
Jagger then went on to win Races 4 and 5.
