I will make more of an effort this year to eat try the cuisine of the Country where the GP is being held (particular highlights are the Belgian GP and getting some nice Belgian waffles in)
For Australia I'm not so sure they have any real distinctive cuisine but a quick look on the interwebz I found this:
The Australian hamburger is, at its simplest, a fried beef patty, served with shredded lettuce and sliced tomato in a (usually toasted) bread roll. Tomato sauce (similar to ketchup but made with less sugar with a more liquid texture) or barbecue sauce are almost always included. Beetroot, pineapple and fried onions are also extremely common additions. Other frequently-served hamburger options are bacon, a fried egg and cheese. US-style pickles are rarely included, except in burgers from the usual American chains.
So I might try something along those lines
