Oh Dear
Dubai will be your life, the traffic, the sand, the gruesome heat, the injustice, Ramadan. EK is Dubai and without Dubai there is no EK. We all made the choice. We can hope , pretend, think of a better life. It is how it is. If you husband wants to join EK be prepared to live here, your kids will grow up here. The schools are good, life for western expats is good, working conditions are good, you will get used to it, even to the driving. Of course I would also rather live in Australia, but you cannot have both. If SAA is good for you, the crime in South Africa is still the lesser evil than drivinging in Dubai (wonder how that could be) then I would suggest you to stay where you are. But commuting impossible, he will maybe have 4-5 full days at home in a blue moon. With these rosters it will definitley kill your husband.
