It's probably not worth stressing too much about suburbs at this point. Research where the good schools are , and browse around realestate.com.au to get an idea of how the prices vary, but that's that.
I say that because a very common experience, which we see related here on the forums a lot, is that people put hours and hours of effort into researching suburbs before they arrive - and then when they get here and drive around, they realise that the "feel" of a suburb is something that's impossible to judge from a distance. It's very easy to get completely the wrong idea and build up an inaccurate picture in your mind.
You'll have to book holiday accommodation for your first four weeks anyway, and that's when you hop in the car and drive around to check out areas.
Your biggest priority right now should be decluttering, because it will take a lot longer than you think! Also do a trial shop to see what it would cost to replace your house contents. You can use harveynorman.com.au or ikea.com.au for furniture, petersofkensington.com.au for pots, pans, crockery etc. Myer.com.au for things like towels or Kmart.com.au for cheap alternatives. A lot of people think they'll sell/give away all their stuff and "start afresh" in Australia, then get a rude shock when they discover how much it's going to cost to replace.
