Prior to the race, it was announced that the duration would decrease from 27 to 19 laps on the grounds of safety, with tyre degradation throughout practice having been significantly higher than expected on the newly-resurfaced Phillip Island circuit. Furthermore, all riders would be obliged to pit for bike changes on either the ninth or tenth laps of the race, while also running the harder available compound throughout.

A stupid and disrepectful thing to happen: Someone is flashing a LED on  Lorenzo's helmet. 

A clean start saw no fallers, with Marquez (Repsol Honda Team) attacking Lorenzo at the Honda hairpin but the Yamaha Factory Racing man immediately retaking the top spot on the run into Siberia. The sensation would come with the mandatory pit window, with Marquez’s teammate Pedrosa first to peel off from third place at the end of Lap 9 and followed by numerous other riders.

Lorenzo would pit at the end of the tenth tour but, having expected a pit lane duel with Marquez, saw the 20-year-old rookie continue for another circulation of the circuit. Marquez then pitted at the end of Lap 11, outside the pre-determined pit-in window of Laps 9 and 10. In a remarkable twist for the 2013 World Championship battle, Marquez was disqualified as was Australian Bryan Staring (GO&FUN Honda Gresini) as the same error had been committed.

Having escaped a touch with Marquez as the latter rejoined from the pits, Lorenzo went on to claim win number six of the season; this also marked the first time since 2006 that a rider other than the now retired Casey Stoner had clinched victory at Phillip Island! Pedrosa finished second to maintain his own title aspirations, as Yamaha Factory Racing’s Valentino Rossi beat Monster Yamaha Tech3’s Cal Crutchlow and GO&FUN Honda Gresini’s Alvaro Bautista in a thrilling contest for third, while light rain began to fall as proceedings drew to a close. Bradley Smith was sixth for Tech3, having run as high as fourth thanks to a rapid start, while the top ten was rounded out by Nicky Hayden (Ducati Team), Andrea Iannone (Energy T.I. Pramac Racing), Andrea Dovizioso (Ducati Team) and Randy de Puniet (Power Electronics Aspar) who ended a race as lead CRT for the first time this year. The MotoGP™ fight now rages on to Motegi Twin Ring and the Grand Prix of Japan, with the championship lead having been decreased from 43 to 18 points.

Ultimately, Lorenzo clinched his third pole of the campaign – his first since Jerez in May – courtesy of a best lap of 1’27.899, but this was only after the reigning World Champion’s Yamaha Factory Racing bike clipped a seagull. The margin at the front would be two tenths of a second, with Marquez able to secure the world crown on Sunday if he ends the race with a points advantage of 51 or more.
