Rossi's chance
Whether or not he can celebrate again this season remains to be answered. He last won in Australia in 2014, and with Yamaha team-mate Maverick Vinales having taken the win last year and other podiums since, that is good reason to believe the bike can do it again.
And Rossi? Motegi wasn't the best preparation, but you don't get to 400 starts without the ability to bounce back like no one else.
Miller, Quartararo in focus
Meanwhile, Jack Miller (Pramac Racing) also has a target on Fabio Quartararo's back. The Australian races on home turf with some serious determination to do well for the home fans and get another top result this season, but that is also compounded by crunch time in the Independent Team rider standings.
Quartararo, who already bagged the Rookie of the Year honour, is currently 38 points clear of the Aussie, so it could well be decided on the Island.
Team standings
Then there is the team standings, currently led by the Ducati Team. But it is only 17 points the difference, and with Marquez on a charge, it could change hands, but Ducati team-mates Andrea Dovizioso and Danilo Petrucci will be pushing hard to try and hold onto it.
Dovizioso also has second in the standings ready to wrap up, and Petrucci is running out of time to hit back again Vinales and Alex Rins (Team Suzuki Ecstar) in the fight for third.
Up for the grabs
The Australian Grand Prix has everything up for the grabs-- Championships on offer, milestones on the horizon, a dash of intrigue and one of the greatest racetracks in the world.
So this year at Phillip Island, one of the most beautiful race tracks, it is all about milestones and titles. You simply got to tune in, and you can do so at 3pm local time (9.30am IST) on Sunday.
