Despite coming fourth for the round after a crash in race three, home track favourite Regan Duffy managed to hold on to his series lead to take the championship in the 65cc 10 to under-13 division.
Fellow local rider Navrin Grothues took third for the round, but it was his time to shine when he claimed the 85cc nine to under-12 State championship ahead of Duffy who again crashed in the second race.
Brother Caleb Grothues also performed well, winning all three 85cc 12 to under-14 races to secure the State title.
He also took two wins for the day in the 100-125cc 13 to under-15 division, but it was not enough to make the podium for the series.
Winning the fourth title for the northern suburbs, Jake Pruiti also took all three wins for the day to claim the 128-150cc/250cc 15 years State championship.
Other State champions crowned were Liam Atkinson (50cc auto seven to under-nine), Jasyn Roney (65cc seven to under-10), Corey Draper (85cc 14to under-16), Baylee Webb (100-125cc 13 to under-15), Jacob Schaafsma (100-125cc 15 years) and Connor Teirney (128-150cc/250cc 13 to under-15).
