The vast majority of GA careers have long periods in the "slave" system at flying schools , where you man the reception full time, only get paid for flying hours - how wonderful providing free labor to a business owner, or on the "casual list" at a charter company, or working for free tossing jumpers.
Long perods of unemployment , under employment , unpaid employment , seasonal employment, months wasted looking for jobs , traveling around Australia just for interviews.
Massive glut of people under 500 hours looking for work.
Leave school , get CPL/IR spend likely $90 K doing that , you are now at least 19, then go GA
70% of your cohort will have dropped out with two or three years, never got one flying job or not prepared to leave the city , don't fancy the reality of the work situation outlined above.
Those who in ten years have 4000 hours will have done exceptionally well, and you can now apply for an airline job. Sure there will be a rock star who has 7000 hours but they are maybe like one in 100.
But unlike others in their twenties you won't have bought a house , had decent holidays , or have many assets, lot's of missed relationship opportunities that will never come back (most partners won't move to the outback). Massive missed career opportunities in all sorts of other fields. You can never get those back , go back to uni at 28 to do a health/tech degree - it just won't happen. But hey that big break is "just around the corner"
GA wannabes need to think about the reality of how their life will be instead of swallowing the "jet in 5 five years" rubbish promulgated by the flying schools.
The speed of the responses here clearly indicates people who have plenty of time on their hands , unemployed likely
