Jeffrey Street or Jeffreys Street is a street located in Kirribilli, famous for being one of the most popular vantage points for views of the city skyline of Sydney, the Sydney Harbour Bridge and the Sydney Opera House. The street is located on the Lower North Shore of Sydney Harbour, directly across the harbour from Circular Quay and is a popular destination for tourists, particularly on Australia Day and New Year's Eve. The street leads uphill from the harbour in a northerly direction to the small shopping village of Kirribilli. For many years the area was called the North Shore and the original land grant changed hands a number of times. Over the past 200 years the area has also been called Huntershill, St Leonards, North Sydney, "Kiarabilli", Milsons Point and "Kirribilli Point". The modern spelling Kirribilli was first used in 1853 and the use of Kirribilli as a locality is more recent.
