There are no dangerous animals in Australia, BUT we have crocs that will kill,some of the worlds most poisonous snakes, octopus that will kill, spiders that will kill, even some fish that will kill if you step on them, but apart from them it is a safe place to visit. The digeridoo's are made from trunks of tree's that have been eaten away through the middle by white ant's (termites).
I would not move anywhere else, it's lovely here.
