I was at the Luna Park auction and I bought Aquarius. I think I paid $140. There was a fairly big crowd and everything was auctioned (even the signs that said "mens toilet"). It was sad to see the old park end its life. Tony Mather has a fabulous video on the history of Luna Park.
A few weeks before the auction, I talked my way in and got to wander around the park. It was like a ghost town and if time had stood still - there were still coffee cups in the tearoom that had been left there since the fire.
Here are some of the photos I took at the time
