Hi ozzie girl, with your query, a friend of mine who is already working for EY for about years now suggested to bring 2 phones. One having UAE's nationwide sim card "ETISALAT", then the other one is for your sim card there in Australia, just let in be roamed before you leave the country. Your family and friends can save tons of money contacting you to your Aussie's sim then you reply with UAE's sim. However it also depend as to how much vodafone will cost international( network to network) call and sms. Here in Philippines, its so cheap that i'll definitely do this way. And don't forget you have the option to use PC communicating with them as well
By The Way, congratulations! and see you there
Hope this will help
