Hi Ed,
welcome to DB forum, this is a great place to learn and share about diving. There are a few other aussies here, I live in ACT, which is a funny place for a freediver.
There are a few freedivers floating around sydney way, lots of people that spearfish. Can try looking at buddy boards on these sites if you haven't already found them:-

P.S. Jim, Sydney is about as close to Perth as Newyork is to LA.
