Don't believe everything you see on TV dood.
Yes, there are a crapload of jobs going up north at the moment, but things are no where near as awesome as 60 minutes make out. Firstly, the idea that anyone with zero experience can just walk on to a mine site is a joke. There is a mines health act (law) in place in WA that says that there are a heap of inductions and stuff you have to go through before they will let you anywhere near the front gate, and that isn't anything to do with what you will be doing once you get on site.
The only accomodation on offer at the moment is "basic" to say the least. Unless you are employed by a big company that already has housing available, you will find it pretty hard to find somewhere to stay. I have a mate paying about $550 a week for a caravan site, and rentals in places like Tom Price have gone past $1000 per week for a 3 bed fibro house.
My best advice w2ould be to contact the HR department in a few of the larger companies (Mcmahon construction, Roche, Clough ETC) and talk to them about what they are looking for. Chances are, they will put you onto a HR provider they outsource to and go from there.
Just don't think you will be able to move over here and start earning squillions of dollars straight away with no quals. If that really was the case Perth would be a ghost town by now.
