Get your missus qualifications attested by DFAT & UAE Embassy Canberra before you leave Australia.
I brought my then 13 year old over with me 2 years ago, a few tears at first but she loves it here (Abu Dhabi) now.
Schools are good if you can get her into one, however they are very expensive (AU$10,000+ p.a.) but your education allowance should cover 1 kid.
Dubai is after controllers and they have a very good package AU$200K+ p.a, Abu Dhabi is desparate for App & Area but the pay is a lot less, AU$145+ p.a. Area Radar (less for App...and so it should be too..let the flaming begin

). Min accommodation costs in Abu Dhabi AU$60+ for 3 bdrm apartment if you can get one, there are plenty of AU$100+ p.a. villas. If like me you get on the Serco contract my 3 bdrm flat is AU$25K p.a.

Dubai accommodation is more affordable and a bit more plentiful, better still the Dubai guys can actually buy property that exists.
Teachers salaries are garbage but it all helps, expect about AU$3K p.m.
Best advice come here with the family before signing anything.
