In page Sutherland, New South Wales:

"

Thomas Holt (1811–88) purchased 13,000 acres (53 km2) in the 1860s that stretched from Sutherland to Cronulla. The Sutherland area was originally heavily timbered and timber-cutting became the first industry. Holt initiated many commercial projects including timber cutting, coal mining, sheep farming and oyster farming. He built a forty-room mansion called Sutherland House in 1881 at Sylvania, on the bank of Gwawley Bay. The mansion was destroyed by fire in 1918, thought to have been deliberately lit.[2]
