Wisdom tooth removal in sydney, australia?

I believe my wisdom tooth is coming out. Not 100%, but am pretty sure. Just rang up a few dentists and found out its going to cost $300 or there abouts. I dont have private medical insurance, and i dont have that sort of money to spend. Anybody know where i can get my wisdom tooth pulled out for free? or will i have to settle with a bottle of scotch, a pair of pliers and a new you tube video?
