The Lower North Shore refers to the Sydney Harbour Peninsula that is located on the north side of the Sydney Harbour Bridge. The three bodies of water that surround the Lower North Shore are Lane Cove River on its western boarder, Sydney harbour on its south side, and Middle Harbour on its east. The Lower North Shore borders the Upper North Shore when the Lane Cover River and Middle Harbour are at their closest.
Lower North Shore encompasses suburbs belonging to the local government areas of Municipality of Mosman, City of Willoughby, Municipality of Lane Cove, and North Sydney Council.
On the 12 May 2016 the NSW government proposed merging the 3 of the 4 Lower North Shore Councils (Municipality of Mosman, City of Willoughby and North Sydney Council) to form a new council with the proposed name of the "City of the Lower North Shore", and propose Municipality of Lane Cove would be kept separate but surrounded by the City of the Lower North Shore under a different council.
The Lower North Shore adjacent suburbs to the water are Neutral Bay, Greenwich, Waverton, Mosman, Cremorne, Lavender Bay, Milsons Point, Cammeray and North Sydney.
