A few more observations from personal experience...
There is a much bigger aviation world out there than a SYD based regional position. I didn't finally buy my own home in a Capital City (Perth) until I was 45 years old.
I'd be looking to break into the WA aviation game if I was looking to further my career.
A 4 bedroom house can be rented for $370 pw only 5 mins to the airport
The median house price has plummeted over the last few years.
I agree that family should come 1st over persuing an aviation dream. That's why I didn't get married until I was 35. I also caution anyone who asks that unless you start your journey passionate, footloose and fancy free in your 20's, your chances of eventual success diminishes exponentially. It's just an observation of mine that to succeed all the way in this game sacrifices must be made in the beginning. Nothing's changed. From where I sit now in the L seat of a major Aus airline, everyone beside me has had similar tales of sacrifice to tell.
