Yup australia is really a nice place, too bad its really costly..
Did you know that Australia has 9 out of 10 of the most venomous snakes in the world? They also have spiders with flesh eating venom and spiders the size of your hand. Kangaroos are really the least of your concern, they are kinda annoying if you hit them on the road but Wombats and Drop Bears are more of a concern since they might attack you and if you hit them they are so solid that they mess up your undercarriage. Oh yeah, you also have a lot of wild dogs, Dingos are really only active on Fraser Island but peoples dogs are probably more dangerous. There are also lots of bats, and you definitely don't want to go swimming in the ocean up north during the wet season because there are a lot of jellyfish and probably not in the rivers either since there are crocodiles, and then there is also fly season.
No wonder they sent prisioners to Australia......
I believe that only if you go to zoo or some forest....
