If you will consider travelling down to Moorabbin, drop in to see Steve Galjar (CFI) at Melbourne Flight Training. I approached many of the schools here recently, wanting to get back into it after 6 years out of the cockpit. Most weren't particularly helpful, but Steve took half an hour out to show me everything I would need to study up on, gave me some paperwork about procedures that have changed, and all for nothing. Again, they had the approach "Let's go for a fly and see where you are at". Not the cheapest, not the dearest but they had the best attitude so that was enough for me....
As for the BAK course, I wouldn't bother. Buy the study books and just work your way through it. I think the theory courses are the biggest rort, the stuff is pretty straightforward and texts like the Thom series are very easy to understand.
