Derwent Park was purchased by John Curwen Walker for ₤1,345. Walker was the accountant at the Derwent Bank and had been renting Derwent Park before it was put up for sale.
Henry Benjafield purchased Derwent Park for ₤4,600 in November 1891 and almost immediately sold it to the Tasmanian Government for ₤5,200. This caused some controversy in Parliament when it was suggested that Benjafield had been secretly acting on the Government's behalf but there was no evidence to support this and it was generally accepted that the Government had got the property at a good price.
