He had parkinson's disease and was never the same after the Commonwealth bank closed up their theme park on the central coast but not before charging them a 27% interest rate.
Another victim of the Commonwealth bank.
Leyland Brothers World
In November 1990 the Leyland Brothers opened the theme park Leyland Brothers World, on a 40.35ha property at Bundabah on the Pacific Highway north of Newcastle, New South Wales. It included a 1/40 scale replica of Uluru, as well as amusement rides, playground, roadhouse, museum and a 144 student capacity bush camp.
In a 1997 article in the Sunday Age, Mike Leyland said that the initial AU$1 million loan blew out due to rain during construction and a 27% interest rate. In July 1992 Chris Palmer of BDO Nelson was appointed receiver and manager of the park when the Leyland Brothers company failed to meet its loan commitment to the Commonwealth Bank.
Auctioneers Colliers Jardine estimated the yearly attendance of the park to be about 400,000 people, with 10,000 students for the bush camp. After an auction held by the receiver on November 26, 1992 the theme park was sold for $800,000, with the buyer planning to upgrade the roadhouse that served motorists and truck drivers. The brothers went bankrupt.
