Tecman - Many thanks for the information I will look into a Barista course here in the UK if it will put me ahead of other personal applying for jobs.
I appreciate all the advice & have done many calculations and still don't see why it isn't achievable with dedication & hard work.
Having a look on SEEK etc I have come across numerous "casual" jobs for people like myself on WHV (Kitchen Hand - I have 1 & 1/2 Years Exp, Bar Work & Fruit Picking) being the most common.
As for accommodation you can score very decent flat shares or even stay for free in a hostel/family if you muck in and help out for 10-15 hours a week.
As I have said before I do appreciate all the advice but it's something I want to have a go at and at least say I tried. If it doesn't work out it will still be a great year spent away and i'll no doubt make friends for life.
Greg
