Meanwhile, Lewis Hamilton was beaten in both sessions by new team-mate Charles Leclerc, who set the fastest time of the day in the second hour of running.
It was a big crash for one of the younger drivers on the grid that was the news of the day though, Ollie Bearman demolishing his Haas with the assistance of the Albert Park barriers, with the damage so extensive he couldn't do a single timed lap in FP2.
The session was red flagged after just 20 minutes after some drivers ran wide and kicked up a troubling amount of gravel onto the racing surface, with the delay lasting about five minutes.
While teams will be a little wary of reading too much into Friday practice, pace in this session may be more representative than pre-season testing in Bahrain – or at least will give rivals another data point to measure – and Carlos Sainz looked particularly speedy in the surprisingly competitive Williams.
