Last I heard for the 4 day 12hr roster (7am-7pm x2 then 7pm-7am x2) it was about $55,000 and that was including penalty rates. No doubt there would be some overtime, but you can't rely on overtime.
Tiger seem to want experienced people (I know a few with lots of experience, but don't seem to want to pay for it). If it was $55,000 plus shift it would be a better deal.
I know it's a LCC, but it's the old adage, if you pay peanuts, you get monkeys.
