Moto3 world champion Sandro Cortese sealed his fifth win of the season in the Australian round at Phillip Island, as his Ajo team-mate Arthur Sissis wowed his home crowd in third.
With Cortese having wrapped up the series' inaugural title at Sepang a week ago, the pressure was off at Phillip Island.
When the lead battle was broken up by a spate of ride-through penalties for false starts - with front-runners Jonas Folger, Luis Salom and Louis Rossi among those transgressing - Cortese and Monlau's Miguel Oliveira managed to break away.
Oliveira enjoyed a brief spell in the lead, but Cortese had matters in hand. He hit the front for good with three laps to go and duly clinched another victory, as Oliveira secured a career-best runner-up spot.
For the ecstatic crowd, the real hero was Sissis.
The young Australian clung on at the front of an incredible battle for third position to take his maiden world championship podium in the best possible place.
Sissis fended off rivals Alex Rins, Danny Kent, Romano Fenati, Alessandro Tonucci and Efren Vazquez by just fractions of a second at the line after a frantic last few laps.
Maverick Vinales had been in the thick of this battle on his return to the series but crashed seven laps from home.
Sepang podium finisher Zulfahmi Khairuddin led for a few laps early on before drifting back to the tail of the podium dice and then falling when a mechanical problem struck his Ajo KTM.
