Canadiangal75,
1. What do they pay in the UAE? What would you end up with in your pocket (in USD) at the end of the year? I was recently quoted a very attractive figure. To be clear, I'm talking flight ops dispatch, not ground dispatch, but having said that, someone I know is going to the UAE to do ground dispatch, and the $$ are equally good.
2. It's worth a try applying to a few Aussies outfits if working in Oz is your aim. Easier if you are under 28yo, but in any case, I know a couple of the larger operators have been trying to recruit from overseas recently. Note that the salaries quoted above are gross, and that the Aus government are one of the higher taxing governments around. Lastly, dispatch in Oz is mostly limited to flight planning/following - not dispatch to the extent of the USA, which you might be more familiar with.
Good luck
