Take out 6 weeks annual leave- no additional pay for working on public holidays so the extra two weeks is time in lieu- and you're up to 19.6 stick for the week which means a 39 hour work week using Ron's numbers. Simulators, Security and EPs are on top of that- one day less free from duty every two months. Don't forget that most other shift workers also have an RDO a month and normally get to go home every night/day.
You're right, there is not many shift working professions that make you stay away from home a couple nights a week that only pay $50K. Most of them pay a truck load more than that!
