Hey Phil, brilliant news, good luck and I hope it goes well for you.
I went on my own years seventeen years ago but came back after 18 months!.. now I've got the missus and five kids in tow and we are several thousand dollars lighter with our current application (my first
PR visa was about £100 as I remember, twenty quid for the medical and took about 3 weeks start to finish!, nevermind).
Can't complain though, my better half is a nurse so she's 'in demand' (not only from me).
So, my tip, stay a while and if you don't, keep your visa up to date mate!
Best of luck
