Mean High Water Mark, Fort Denison, Sydney Harbour
In NSW, the legal boundary between natural foreshores and tidal waters is commonly mean high water mark (MHWM). For any development on the foreshore of one of NSW’s waterways, the boundary needs to be determined. The location of boundaries helps to understand the extent of the property and what development is permitted. For further information, view the fact sheet.
