Too early to give up
Hi whissper
My advice to you (an advice from a young guy that has joined the industry 2 years ago and recently got licensed).
Don't give up yet I know the apprenticship is the most difficult bit, But it's as the above posts mentioned you might have to consider relocating to even outside of australia if needs must and working as a mech, It's a bit hard to think of but thats how you get by in this field you have to get subjugated at beginning, I agree with you that doing the course without being employed already is useless but you did it now and there is no turning back it's either leave or keep your hopes up in the industry and keep trying, It all comes down to you, whether you're fond of the industry and are willing to compromise or not.
