I commuted out of Hobart for the last few years of my career.
Flights were often delayed, so it was impractical to commute to the job on the same day. That meant having accommodation in Melbourne or Brisbane, which fortunately my contract conditions covered. Also I had some control over time off.
I think you’re unlikely to find such flexibility as an employee (I had my own contracting service). If you fly for a domestic operator you’ll be unlikely to get enough successive days off in a block to make it much fun.
Flights are expensive. You won’t get the jump seat on any commercial flight unless you are rostered with that crew in some official capacity.
If you can set your sights lower than jets, occasionally turbo prop jobs come up in LST with the RFDS, and Sharp Airlines recently advertised for Metro pilots. Lifestyle in Tassie compensates for many things…
