Fabio Quartararo said he is in for "the toughest job of his career" after his crash at the Australian Grand Prix handed the MotoGP title race lead to Francesco Bagnaia.

Quartararo conceded the lead in the championship when he crashed out on Turn 2 of the 11th lap on Sunday, while trying to make up for an early mistake that had seen him fall to the back of the race.

The Frenchman has now failed to collect points in three of his last four races, and Bagnaia's third-placed finish at the Phillip Island Circuit propelled him 14 points ahead of Quartararo in the standings.

Indeed, Quartararo was fortunate the Ducati rider gave up his lead to Alex Rins and Marc Marquez on the final lap.

Quartararo's chances of retaining his title might well be slipping away, but the 23-year-old will give it his all.

"Now we need to turn the page and we only have one job and it's trying to win," Quartararo, who held Bagnaia off last season to win his maiden MotoGP title, told reporters.

"It's going to be the toughest job of my career, but I'm ready to fight for it."

Quartararo gave up the title lead at a similarly late stage in 2020, ultimately finishing eighth, though he does not believe this season is comparable to two years ago.

"[In] 2020 [it] was mentally and technically, and now I don't feel mentally like I'm over-thinking too much or not. So mentally I don't feel it's [like] 2020," he added.

"I'm just trying to do my best and I'm overriding a little bit too much and the risk of having a mistake is really close. So that's what happened."

Rins, meanwhile, celebrated victory in what will be his final race in Australia with Suzuki, who are withdrawing from MotoGP at the end of the season.

He said: "I'm super happy to finish in the first position. First of all it will be the last time with the Suzuki here at the Island.

"I'm blessed that I got the first position for this and then for all the people that were supporting me during all the season, during all the bad moments. The team really deserves [this win] and all the staff in Hamamatsu.

"We really deserve it and in many races we know our weak point which is the qualifying.

"We struggled but in some races we had unbelievable pace and were forced to finish in fifth position, sixth position for this reason. The victory was quite nice. It's sad that Suzuki is leaving but let's leave with the victory."
