Re: Oz rock!
Not sure if you guys know this, but the American perception of Australian culture is quite positive. Of course, what Americans think Australian culture is about is probably mostly ridiculous, but it's perceived very fondly.
The American TV and radio ads for Foster's beer and Outback Steakhouse are great examples. A guy with an Australian accent, promoting "Crocodile Dundee" stereotypes, sells a product. And Americans eat it up, literally.
