We never actually went for it in the end!
We looked into it at length for over 6 months and eventually came to the conclusion that it was too big a risk to take. We did loads of research on moving to Oz and spoke to several people who had already made the switch across from the UK, but most were very homesick for their families in the UK and they said that the cost of living was very high in Oz and that the Australian people just weren't that friendly. Apparently, you DO get more of an "outdoor" lifestyle, but you have to work all hours to be able to actually afford to do anything! Or so I've been told.
Also, my husband had been told all manner of things about the Oz Army that just weren't true, so we decided to stick with the UK instead.
Hope I haven't wasted your time. I perhaps should've updated the thread to say we skipped it.
Wishing you all the very best with your interview. Good luck & please let us know how things go - it would be nice to hear a success story!
