it should, but there are a few things to keep in mind..
u need a power convertor, as the US power supply is 90v (i think) while australian is 240V ..
the power plugs may be different (i dun know about this one)..
US is also NTSC video format, and Aussie is PAL.. so you have to make sure ur TV is NTSC compatible, or else u are stuck in black and white...
i think thats it~!
