I moved over to Adelaide last year and I love it here.
Is RAAF any different to the RAF, thankfully yes! There remains a culture in the RAAF that everyone is expected to do their jobs to their best ability.
The RAAF knows that its to look after the workforce so that it doesn't walk out of the door. (I know that anyone reading this in Oz may disagree but it is only when you have experienced the apathy in the lords & masters of the RAF that you will understand what I mean)
In the sense of day to day working it is very easy to move from RAF to RAAF, some things are differrent but it's like exchanging one bluesuit for another.
I take it that you have seen the defencejobs.gov.au website?
There is a link on there for lateral recruits and an email address. I would advise that you contact Sgt Tanya Horsburgh on that email and let her know your Quals to make sure that they are recruiting at the moment.
The RAAF makes the move to OZ very easy
PM me if you would like any more info
