Farmers are gathering to tidy Camden Haven River during clean-up event called "Tide to Tip" on Wednesday, February 24.

This is the second year of the event organised for 22 estuaries across NSW and Queensland by OceanWatch Australia.

Armstrong Oysters owner Brandon Armstrong said the event has achieved successful results in the previous year and are hoping for a strong showing again in 2021.

"Keeping our estuaries clean and healthy is crucial for our industry to ensure we can continue to supply quality oysters to the community," he said.

"The first year of Tide to Tip was great success and we are looking forward to another great event."

During the event oyster farmers will be cleaning the area, sorting, curating and counting the collected rubbish. A summary of the waste is documented and analysed by the Australian Marine Debris Database,a program run by Tangaroa Blue Foundation.

Last year the 'Tide to Tip" clean-up involved over 250 oyster farmers from 19 oyster growing regions of NSW and QLD. More than 12 tonnes of waste was removed.

Partners include NSW Department of Primary Industries, NSW Local Land Services, Clean-up Australia, Port Macquarie-Hastings Council and OceanWatch Australia. The clean-ups are supported by the NSW Landcare Program, a collaboration of Local Land Services and Landcare NSW Inc. supported by the NSW Government.
