There's a wee track called Philip Island about 1 and a half hours away from the city. You will miss the WSB round on April 3rd? but u might catch a race on the dates you are here?

How about going to see some indoor freestyle motocross in the city's Rod laver Arena. The yanks are coming. Metal Mulisha 28th March.

Rent yourself a bike and go a run down the coast...?

Oh, thats right The F1 GP is on 3-6th March in the city centre.

To be honest you will find something. Mail me if you need a hand to organise something?
