In an apt description of Phillip Island, half the sky ahead of the final practice session was nearly black, while the other half was marshmallows on a light blue background. Making the best of the still dry track, most riders joined the action on the soft rear tyre, with the exception of a couple Ducatis, including Andrea Dovizioso, Jorge Lorenzo and Danilo Petrucci, as well as the Yamaha trio of Valentino Rossi, Maverick Viñales and Johann Zarco.
Marc Marquez trialled both rear tyre options, starting on the soft around sixth position and switching to the medium for the final stage of the session, snatching the lead soon after. The Spaniard picked up Andrea Iannone to inadvertently show him the ropes and drag him into second position. Marquez maintained top spot to the flag and posted a short run of consistent mid 1:29s.
