I think you can pretty much disregard the exchange rate. Even with the new "allowance" you don'y really earn enough here to be sending much back.
You earn Dirhams and you spend Dirhams, there really won't be much left to convert back to AUD. The major hiccup is when you go on vacation and have to convert your Dirhams into Euros or AUD or any other currency that has appreciated against the US$.
If you are married with a kid or 2 much of your money will be spent educating/entertaining them. If you are single an equal amount will be spent entertaining yourself.
If you are considering coming here don't do it for the money, do it for the experience, the adventure and the lifestyle - 2 months leave a year ain't bad either - and, despite SERCO's many shortcomings I have worked for worse organisations.
p.s. If you are from ML or SY and enjoy the weather there you will hate it here. If you are from sunny Queensland it ain't that bad.
