Hi EI,
I live in NZ and there are defiantly more jobs for low timers both here and in aus. The most common areas to get a start are instructing, tuna boats, agriculture, tourism or mustering. (tuna boats a bit harder with low hours). you can get a start in any of these if you have the right attitude and a bit of luck. However coming from Ireland is going to be hard if you don,t have any connects to aus or NZ as it is extremely hard to get into either country to work as a foreigner.
