All the time we were there the dangerous wildlife we saw was either running away from us, or steering clear. The houses and hotels are treated with a special spray, and whatever they use in the swimming pools even keeps the insects out(!). Also a branch of our clan has been out there for 3 months and even their cat hasn't brought anything nasty in

I think whole Australia is very good for travelling. When I joined air-hosts for my profession then my first flight was landed in Brisbane Australia and we really enjoyed this city.
