I'm not in Melbourne, but one suggestion is to get in touch with Grain & Grape. My understanding is they do brewing demonstrations from time to time, and should be able to help you on your way.
Also, there are a number of brew clubs in Melbourne. Why not look to join one and get the collected wisdom of the members at no cost to you apart from possibly a joining fee?
Is there an AHB brewer somewhere near you who can show you how to proceed? Watching another brewer on a brewday is the quickest way to learn, and you might see how straightforward even AG brewing can be.
