The large majority will claim you are too old, expected. I went in late. Similar age, due to another industry (trade) which was more attractive at the time (and still is). However was on the Airbus 10 years post my first GA job. Had kids late, so will probably be working until I’m 80. Age and prior work experience in another field I felt got me across the line. Employers spent more time asking about me previous non aviation job that my flying experience. I got all the jobs first attempt. My competition was 20 years younger.
I would probably get a move on right about now and not let it drag on too much longer. You can get a PPL relatively quickly and CPL can be done fairly quick too if you have time of work, no kids, will help. Get the books now start reading.
The hardest part would be getting the first job. If I was in your boat, I would probably do all the training in Darwin, Perth or Cairns. Cairns I highly regard, due low output of CPLs, highly regarded CFI and local operators will prefer local based pilots.
Ideally out of CPL you want to go into some form of full time job. Doing a instructor rating is another $25k but will potentially have a job lined up. It would be better for progression if you bypassed the instructing path, into some form of CPL full time job, then twin, regional etc. Can be done, and it’s a trend that occurs for those training up the top. Can shave a few years off. It’s all the timing sadly, relationships formed and who you meet.
