wow thx for the info guyz ^^
So I keep trying and find out theres a Game Traders store right near me in Glen Waverly (they have more stores around Melbourne, too). I head down there and ask to preorder a Wii. They say they'll be getting more stock on the first week of January, and if not then, the 2nd week.
I went to Glen Waverly yesterday and asked the person at the target store lol
