 It is bordered by Lake Burley Griffin to the north, Commonwealth Avenue and Capital Hill to the east, Adelaide Avenue and the Cotter Road to the south, and Scrivener Dam, Lady Denman Drive and part of the Molonglo River to the west.Although Yarralumla is one of the largest suburbs in Canberra by area, its population remains quite small because more than half of its area consists of open space or non-residential development, including Weston and Stirling Parks, the Royal Canberra Golf Club, and the grounds of Government House.A relatively high proportion of houses are occupied by diplomatic missions.
