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 like 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 on subdividing or developing the land.
