Replying to Oil Rigs , Jobs ??

Hey Aussies

Im looking for some guidance from the locals


I've lived in Canada my entire life, but I have an australian citizenship, and recently received my Adult Australian Passport.

I will be moving to Whistler in early October 2012, as I have a Snowmaking job lined up, so that I can spend the season shredding in Whistler!
-But this is 5-6 months away.

I haven't been back to Aus since I was about 5, so I Definately want to come back and explore my home-land. (was born in Wagga Wagga)

- For the time in between ski seasons, I was thinking about heading to Aus to backpack around for a month, get all my Aussie documentation, a bank account -- everything i need to be a citizen.

-But after that month, It'll be back to worrying about money. So I was wondering about the Oil Rigs. I hear its great money. How hard would it be to get into a job like that?
Any information on the oil rigs is WHAT IM LOOKING FOR!
My goal is to work for them for 2-4 months before returning to canada. Is this an unreasonable goal?
ANY information or insight is appreciated!!!
