Hi Carin58,
It depends on what sort of flying you want to do. if you want GA type flying you could look at this link.

With those hours you could easily aply for REX, Virgin Blue or possibly jetstar. Just do a google and check out their websites.
Qantaslink are hiring pilots with as little as 200 hours now. Qantaslink fly regional Dash-8 Q300 and Q400 turboprops.
One word though, if you read a lot of the forums on here about T&C's for Aussie pilots here, things aren't all that rosy.
I don't think you would have any trouble getting an instructor job at all although the pay sucks.
Best of luck
Marty
