You will be granted a Sub Class 309 Visa, subject to DIAC review two years after arrival in Australia.
There is no work restriction on a 309 Visa and as it is a Provisional (Permanent) Resident Visa, you meet all requirements for airline employment.
Don't split with the Missus in the first two years or you will be packed off back to the UK! There is no obligation to marry within that two year period, or at all. You will be entitled to Medibank cover on arrival but not entitled to any social welfare payments in the first two years or until substantive Permanent Residence is granted.
