Stephen Edward Perdriau (1858–1931)

Educated at Fort Street Model and Sydney Grammar schools. He became a cadet in the survey department in 1875, licensed surveyor in 1879 and joined the survey branch of the Department of Lands on 2 January 1880. After assisting on the trigonometrical survey at the base-line camp at Richmond, he worked in the North Sydney district until appointed supervising surveyor at head office where he carried out many important government surveys (including Centennial Park) in Sydney and the metropolitan area.

In 1890 Perdriau served on the board appointed to inquire into floods at Bourke and advised on the distribution of relief money. He was attached as special officer to the Parliamentary Standing Committee on Public Works for the 1897 inquiry into the extension of the railway into the city of Sydney. In 1901 he was appointed chief surveyor and land valuer to the new Sydney Harbour Trust; he estimated the cost of the resumption of the private wharves at Darling Harbour at £3.25 million: the actual cost to the government was £3.5 million.
