The lake south of Newcastle is the largest saltwater lake in the Southern Hemisphere.

Lake Macquarie, the largest saltwater lake in the Southern Hemisphere, lies immediately south of Newcastle, providing the aquatic lifestyle environment that complements the ocean beach experience of the city's coastal strip. The lake's 110 square kilometres of navigable water, surrounded by the residential communities of the Lake Macquarie local government area, provide the sailing, boating, swimming, and fishing environment that underpins the lifestyle proposition of the lake's foreshore suburbs.
The lake's foreshore communities, from Belmont and Warners Bay in the north through the western shore communities of Speers Point and Toronto to the southern lake villages, each have distinct characters shaped by their aspect, their accessibility to Newcastle, and their heritage. The western shore's older commercial centres and the more recent residential development of the southern lake provide the full range of lifestyle and housing options within a single local government area.
Sailing on Lake Macquarie has a long history, with the lake's size and the consistent southerly winds of the NSW coast providing sailing conditions that have sustained competitive and recreational sailing for over a century. The lake's sailing clubs, concentrated on both shores, have produced sailors who have competed at national and international level, and the racing programs they sustain provide the regular competition that develops sailing skills and the community connections that club sailing creates.
The lake's ecosystem, while substantially modified from its pre-European state by development, urban runoff, and historical pollution from industrial activities, retains significant ecological values that management programs have aimed to protect and restore. The seagrass beds that support juvenile fish populations, the mangrove communities that provide productive habitat and coastal protection, and the migratory waterbird populations that use the lake provide the ecological foundation for the fishing and wildlife observation that the lake's users value.
