Phillip Island MotoGP: Marc Marquez beats Jorge Lorenzo on last lap

Lorenzo had led for the majority of the Australian Grand Prix, but with second still cut into Yamaha team-mate Valentino Rossi's lead in the championship, the Italian deposed from a podium on the final lap by Andrea Iannone.

Ducati rider Iannone shot into the lead off the line, as Lorenzo jumped past Marquez for second on his Yamaha at Doohan.

Lorenzo then muscled his way past Iannone for the lead, and began to pull a gap after a brief exchange with the Italian.

That escape was aided by a colossal scrap between Iannone, Marquez and Rossi, the latter having picked off Maverick Vinales, Cal Crutchlow and Dani Pedrosa in the opening laps.

Marquez eventually broke away in second in the middle part of the race and began to reel Lorenzo in, before perfecting a pass up the inside at Honda four laps later.

Their scrap for the lead became a four-way one once more though as Iannone and Rossi clawed their way back to the front, and Marquez was shuffled back down to fourth.

Victory looked all but sealed for Lorenzo with the Spaniard again allowed to escape, but after regaining second on the run to Doohan on the final lap, Marquez clawed back ground on his compatriot before stuffing his Honda down the inside at MG to snatch the lead, and the win.

Iannone perfected a similar pass on Rossi at the same turn to complete the podium.

Pedrosa came out on top of another race-long scrap between himself, Vinales and Crutchlow, the Honda man eventually claiming fifth after pulling clear in the final laps.

Pol Espargaro beat brother Aleix to eighth, with a subdued Bradley Smith completing the top 10 on his Tech 3 Yamaha.
