Irishwingz as previously stated Your chances are slim as there are not enough flying jobs to go around in oz, vacancy's are low and job competition is high. Australia is a great place and you will me more than welcome I'm assuming your trying to build hours in which case you can get a good 172 or PA 28 to tour around in for around $120 to $140 oz dollars = 45/50 pounds ( bring a mate pick up other travelers to lower the cost).
Should you decide to try and find meat bombing work (futile but you never know) you will need 200 hrs total time and 10 hours on type as a legal minimum. Established no no's are flying for free, flying without a slimpack, dropping in IMC and flying without a fuel reserve. Please do not do any of these things.
