Speaking of money...
The front page of the Wet Australian last week had the headline story about the pay deal for workers on the Gorgon project on Barrow Island where the agreed minimum wage for labourers was $150K. They did say it was a for a 70 hour week though. While that sounds like a lot of hours the reality is that there's bugger all to do if you knock off at 3pm anyway so you might as well earn more money. I say this as someone who worked on a remote farm in my early days. No point working less than a 10 hour day, what are you going to do when you knock off?
I think it also said it was 21 days on, 9 days off but I may be wrong. Three weeks straight without a day off is hard in anyone's language.
There's a reason booze is so expensive up there too. When you're earning that much, the bars can charge it, and the fact they are usually so remote makes the justification for them even easier
If I were to work up there, I think i'd buy up a bar. Would seem like an easier way to make money
