It's a generic commercial resort full of tourists, probably lots of Americans. It's where the international money goes, but it's not particularly "uniquely Australian." Depends what your story is doing, of course, but for a more genuine Australian flavour nowadays, it's eco-tourism resorts that put you in the desert or the rain-forests, or down in the Tasmanian wilderness. Or anywhere in the Northern Territory, but there you have the famous Australian road killers and crocodiles to deal with. Palm Cove is mint juleps beside a blue pool and a bad pianist in the evening.
Don't forget a cyclone or two. They trundle into the gulf every year, throw down more rain than Noah ever saw, but nobody notices because there aren't many people there, and the ones who are there have big boats and can swim.
Drizabone is a bit dated now, try looking up R M Williams stuff it's what the jackaroo's are wearing this season
