How can I get a bike mechanic certification/where can I learn to be a bike mechanic? I'm interested in becoming a bike mechanic in Melbourne, Victoria, Australia. 

I'm hoping there's an industry body which runs courses to certify bike mechanics. 

I'm really hoping it's not just learn on the job from an existing mechanic because I've had a really bad experience with local mechanics lately they don't have a clue what customer service is when I buy from them and need a return.

Are there any courses or certifications to become a bike mechanic?

In the UK, Cytech are the most recognised body; Contact them and ask if they're aware of an equivalent organisation in Australia.
