Nico Rosberg has taken the blame for his crash in FP2 in Melbourne, saying he "accelerated too much" in wet conditions.
With changing conditions prevailing all day around Albert Park, drivers were challenged to stay on course, and a few - like Rosberg - were caught out by the tricky circumstances.
The Mercedes driver hit the wall at Turn 7 during the wet second practice, which resulted in a heavily damaged front wing on the W07.
"The conditions were OK - on the edge but they were fine," Rosberg said.
"I accelerated too much and got it wrong. It was good for me that the track didn’t dry out because I didn’t’ lose any dry running as a result, so no downside from that."
As for all of his colleagues, the German driver will be forced to compress a fair amount of work into FP3 tomorrow.
"Tomorrow is going to be a big day though. We need to practice for the race and for qualifying in the morning, then we get straight into qualifying in the afternoon.
"First time on the supersofts is going to be exciting, lots of grip, new qualifying rules, all that together is going to be a lot going on.”
Asked why he stopped on track when he had almost made it back to the pits, Rosberg replied:
"Because my front wing was stuck under my car and there was a risk it could have come loose and then cause a lot of debris.
"For sure [it’s frustrating], because the car was maybe OK apart from the front wing so I was looking to get back out again in that session."
