When I was there FI's were on around $70 000 per year, GI's were on $60 000. Accommodation was around $15 000 per year, which is enough for a modest house. Generally the cost of eating out etc is quite high as the only decent places to go are quite expensive.
You need to weigh up the bull**** with the money, and in my case the bull**** bucket got filled up first. The salaries are quite good for the southern hemisphere guy's, so for some of them the balance of money to bull**** is in their favour. Perhaps thats why BAe Adelaide are advertising for the new HOT
Best Wishes to they guys that are still there, they were a good team, and a great bunch of guys to work with, despite the conditions.
