Monitoring our Coastline


Our region’s coastline extends from Point Plomer in the north to Diamond Head in the south. Some of the ways we monitor and manage our coastline include:

Water quality testing

We regularly conducts water quality monitoring for our key estuaries and rivers. Water quality monitoring is conducted at Lake Cathie, Duchess Creek, Saltwater Creek and Rainbow Beach.


This is a low-cost method for mapping shoreline change using smartphone images collected by the community and uploaded to social media platforms. CoastSnap turns repeat photographs at the same location into coastal data that can be used to understand and forecast how coastlines might change in the coming decades. 

CoastSnap locations include:

  • Town Beach, Port Macquarie
  • Flynns Beach, Port Macquarie
  • Shelly Beach, Port Macquarie
  • Lake Cathie Entrance Lookout, Lake Cathie
  • Jonathan Dickson Reserve beach access lookout, Lake Cathie
