Hey
Ozziegirl,
congrats, u r finally here!
As for the contract they should send u copy through email, as u need to sign one page and fax it (or email it) back. They will do the visa for u as well, and they will send u scaned copy on email. U must print that copy as u will travel with it and enter UAE.
They should also send u all these data on email or u can rush them, as they can be quite slow sometimes. For example I got my ticket 2 days before trip!
For the driving license u have to apply in UAE. If u already have one, than all u have to do is to transfer your aussie license to UAE one (again in UAE).
