I think you'd need to be a bit more specific than that. I can give you some general guidelines like:
- We do not really have kangaroos hopping down the main streets of our capital cities. (Except for Canberra, where it does happen occasionally.)
- But we do have sharks. Do not feed the sharks, they are not friendly.
- The movie "Crocodile Dundee" was not a documentary. The overwhelming majority of Australians live in cities and do not say things like "Stone the crows, cobber, I'm flat out like a lizard drinking". (Don't ask.)
- That doesn't mean that you shouldn't explore the countryside, of course. There is some beautiful countryside for all tastes, from the hot rainforests of northern Queensland to the temperate east coast to the cool climate of Tasmania to the spectacular deserts (yes, really) of Western Australia. (Though if you go to Western Australia, Margaret River in the south west is a must.) Where you go depends on the kind of climate that you like.
- But what I said about the sharks also applies to the snakes. Still, if you make enough noise walking through the bush the snakes will usually avoid you.
- Your Euro will go a long way in Australian dollars. Which is good for you, and very bad for me when I was in Europe last month.
- Australia is big. Yes, I know you can tell that by looking at a map but a lot of tourists don't "get" that until they get here. Some think "Oh, I'm in Sydney, I'll just drive over to Perth for the weekend". It is a five. hour. flight! One does not simply drive from one end of this country to the other.
- If you plan to go city to city, best that you fly. If you plan to go to major country towns, we still have an adequate train service, though nowhere near as good as Europe's. The rail lines to most of the smaller country towns have been torn up in the last 20 years. (Continued)
Boy I really, really hate Italki's 2000 character comment limit. But anyway...
- If you drive, we drive on the correct ( 8^> ) that is, left hand side of the road. If you have been to Britain by car you should be OK. We have a relatively decent highway network. Fuel is neither ridiculously cheap nor ridiculously expensive and again the fact that you are buying dollars from Euros helps. Avoid driving to the inner cities if you can; parking is ridiculously expensive. It's better in the outer suburbs and easy in country towns. Get at least a medium size car if you are travelling long distances.
- City cafes close ridiculously early in Sydney, though there seems to be more of a choice in Melbourne after dark. If you are going out to eat look up the Good Food Guide (published by one of the country's newspaper companies) for that city to get some ideas.
If you have any specific questions, please feel free to ask them...
The journey there and back is a long one. There are quite a few wonderful stopover destinations you could visit.
