Woollahra House refers to two mansions built on the same site in Point Piper, Sydney, New South Wales, Australia.

The gatekeeper's lodge from Sir Daniel Cooper's house, which was built in 1871, is now the Rose Bay Police Station, and the stables which are now Wyuna Court, a prestigious block of apartments.

He returned to England at the age of 14 to complete his education but came back to Australia in 1843 and became a commercial partner with James Holt.

[2] In 1856 Cooper started building Woollahra House, and to mark the occasion he held a very large ceremony to lay the foundation stone, at which 400 guests were present.

His parents were William Hill and Mary Johnson, who had both been convicts and had subsequently acquired wealth through business.

[7] Hill became a wine and spirit merchant, and by the time he moved into Woollahra House he had retired and become a naturalist.

He was elected committeeman of the Australian Jockey Club in 1887,[11] but in the following year he resigned as the family decided to live in England.

Although he left Sydney in 1888 William Cooper retained ownership of Woollahra House until 1899 and either rented it or allowed his friends and relatives to reside there for short periods.

Isabella Martin was born in 1832 in Sydney; the eldest daughter of William Long, who owned Tusculum in Potts Point.

[16] In 1882 she left her husband and, with her own wealth, rented houses further away from the central part of Sydney.

Sir and Lady Astley Paston-Cooper were English and they lived at Woollahra House during a visit to Australia from 1896 until 1898.

A tent was erected on one of the terraces of the lawn, where everyone regaled themselves with delicious strawberries and crem, a luxury that seems one of the chief attractions of garden fetes.

Tea and dainty sweets were served in the ballroom which was generously decorated with masses of arum lilies and the choicest of other blossoms.In 1898 William Cooper decided to live in England permanently.

One of their sons, William was a very good swimmer, and while he was a resident of Woollahra House, competed at the 1912 Olympic Games.

Longworth also had interests in brickworks, potteries, timber-mills and pastoral properties and accumulated considerable wealth.
