Water boundary determination

Waterways, including oceans, rivers and lakes, adjoin property across NSW. The beds of most tidal waters and non-tidal waters include Crown land.

Over time, these physical water boundaries can change from natural causes such as erosion. This means the current land title may not necessarily reflect the location of the actual boundary. You can complete a water boundary determination if you plan to subdivide or develop the land.
