possibly moving to Australia

Im trying to get info on water temps and what kind of breaks and hazards and whatnot. I have 2 little girls, oldest is 3 and youngest is 2 months. Of course Im not thinking of throwing them in the water right yet or anything, but looking for places that would be family friendly as well as good for myself.
Looking at mostly Western Australia, Northern Territory, Victoria, (Australian Capital Territory is also recruting for job) or also I guess New South Wales as far as territories to move to.
Also I like to fish, any info on saltwater fishing and/or freshwater would be cool to get.
