In the World Championship, Bagnaia now leads by 14 points over Quartararo, with Aleix Espargaro another 13 back and Bastianini also still in contention at 42 points off the pace.
Leading the way in Free Practice 3 with a blisteringly quick lap to put him 0.130s ahead of the pack, Honda's Marc Marquez started Saturday in supreme style.
Prima Pramac Racing rider Jorge Lorenzo broke all time lap record which dates all the way back to 2013 when he set a 1:27.767 on his Ducati Desmosedici.
The final three races of the year are now underway and the Honda Team arrive back in Australia looking to end the season with a strong push. Phillip Island is known for producing incredible close racing and both Marc Marquez and Pol Espargaro will be looking to draw on past Australian success.
