With Sydney Harbour as its northern boundary, and the Pacific Ocean to the east, Vaucluse is sublimely sited for luxurious living. Its earliest residents were the pioneering Wentworth family who built the family home, Vaucluse House, which is still in the crook of a valley encircled by Olola Avenue. Since the early part of the 20th century, Vaucluse has been home to Sydney's affluent either in their waterfront mansions or on large hillside tracts with magnificent views.
