Arnold Schwarzenegger is in Melbourne to promote his body building and multi sports competition, but he is not the only one showing his strength in the city, after a dominant display from Mercedes.
That's all from us for coverage of Australian Grand Prix practice. If you are just waking up then have a read of Andrew Benson's report.
We'll be back early on Saturday morning to guide you through third practice, and then qualifying. Join us again then at 02:30 GMT. See you later!
