Hi, I think you'll find the reg is actually VH-BUC, or at least that's what it looks like when I blow up the photo and I think the parts of letters you see on the side of the 'aircraft' in the photo is the end of the reg number. This would make it this Cessna skylane 182D:
Aircraft VH-BUC (1960 Cessna 182D Skylane C/N 18253045) Photo by Graeme Jenkinson (Photo ID: AC157862)
History here if you're interested:
VH-RHE
So here's a photo of a skymaster's dashboard, it's a slightly later model as it's a 'Q' but it's broadly similar:

I've also found a B.J. Crowe, but whether it's the same person or not I don't know but given his job it would be reasonable to suppose it might be. He is or was an Engineering officer for Qantas working on Constellations and B707's.

Finally if you go back to the 'Adastron' website on that above link
ADASTRON Home Page there's a link to the Queensland Aircraft museum, you 'may' get somewhere asking them if they know anything.
All gleaned from deep digging on the web from half a world away
. Hope that helps.
As for the simulator itself you'd need to look underneath as to what sort of hook ups it's got as the one thing that strikes me from the photo is that there's no display apart from the instruments for the pilot so should it be located in a room with a projector screen or is it a sort of link trainer with a hood and 'flying' on instruments only. If it's as old as the BJ Crowe links suggest then it may not have a computer associated with it at all. Or he may have been waiting for computers to come along to create it. Good luck with your search.
