Just be wary of alot of people in Australia who in recent times have had a awesome run in terms of job progression. Learning to fly to flying a jet in less than 5 years is not the long term average for career progression.
Plenty of people in the 45+ age bracket these days would have had runs of 10+ years to a jet most of which would have been on well below an average income. Once upon a time you needed 5000+ hours to be competitive for entry to a regional airline because that's just what everyone had.
You are not to old by any stretch and I would suggest that you may have to consider a stint overseas if to want to fly a jet at some point as the Australian job market at the moment is not all that good. However you have to be in it to win it and to a certain extent you make your own luck but just have some sort of a plan for your career and finances if you get stuck on the ladder on the way up, usually due to no fault of your own.
