The rides may still be owned buy Sunway. Maybe they are going to Asia for there new park. They may have had a deal with ING to leave them there till they were ready and just payed a lease on the land until such time as they were ready to move them.
What happen to the member that posted the pics up of the park being demolished? is the site with the pics up and running yet? I seen as i was driving past today they were knocking down the line up covers for the Snowy River Rampage.
I still wouldnt mind taking a Helicopter ride over the top to have a look.
