Hi Elias.K, the CASA website does have a bit of info available regarding how to become an AME and then a LAME - but obviously not so much in relation to specifics about apprenticeships, etc.

This link from the Vic government website might give you some more specific information. The link is for a framey, but all the categories are there.

Good luck in your endeavors. I'd recommend scouting around Moorabbin - but I think at this stage that's a bit premature, have a look at the best way for you as an individual to break into the industry to start with. The market is soft, but I did leave the area three years ago so I'm only basing that off my mates still in the east.
