Not specifically about VCE tutoring, but some ESL programmes for new arrivals to australia run tutoring programmes which offer training.
eg.,
http://www.ames.net.au/volunteer-tutorsI have no experience with them, have just heard about them from a friend. There are others if you look around on the web or use the phone and ask around.
Your university may even have some programmes or affiliates who train tutors.
There are some training courses run in the city which train you to teach english overseas, but also include training in different teaching methods . They run for a few weeks during semester breaks usually. google is your friend there. (tesol, tefl, etc)
Also, have you thought of asking your teacher from last year how to start off tutoring? People often love it when you ask their advice on their area of speciality.
