Vaucluse is an eastern suburb of Sydney, in the state of New South Wales, Australia. It is located 8 kilometres north-east of the Sydney central business district, in the local government areas of Waverley Council and the Municipality of Woollahra.
Vaucluse is located on the South Head peninsula, just South of The Gap with Sydney Harbour on the west and the Tasman Sea to the east. The Sydney Harbour side of the suburb commands views across the harbour to the Sydney Harbour Bridge. The adjacent suburbs are Watsons Bay to the north and Rose Bay and Dover Heights to the south.
Vaucluse is a mainly residential suburb. For many years it was the most affluent suburb in Sydney and as of May 2017, in terms of houses and properties, was in the top five most expensive suburbs. Tahiti, a Hawaiian-style residence in tropical gardens above Hermit Bay, set an Australian residential record when it sold to a trio of South Africans for more than A$29 million in September 2007. The Australian residential record was overtaken by Leon Kamenev, the founder of Menulog, purchasing four waterfront properties on prestigious Coolong Road for a combined A$80 million in April 2016.
