PCX, I don't know what you're banging on about, my comment wasn't aimed at you. Many pilots, including some on the previous page, seem to think the local aeroclub's synthetic trainer counts as a simulator.
Nevertheless, para 4.1 of CAO 40.2.1 says the renewal can be done in an approved flight simulator i.e. the type airlines use and Ansett in Melbourne has. I'm not sure if Ansett does training or IRRs for non-airline affiliated pilots anymore - I heard their approval to do so was pulled earlier in the year.
