Like ramsey-48408 said I don't understand why they couldn't just set it in Australia where it is obviously filmed. As it is it's largely a series of good to bad American accents and the occasional US flag on someone's shoulder to say...SEE! It's America. They couldn't even get the steering wheels on the correct side for the US.
My advice is just to let the Australian accent fly and there would be a great improvement!
