Event coordinator Josh Holliday said that nearly 100 participants registered for the event, which saw 83kg of waste removed and another 63kg retained for recycling.

"We also saw 290kg of clothes, books, toys etc. donated and traded for trash," he said.

Participants traded trash for treasure in a waterway clean-up event where the litter collected became the currency to purchase quality pre-loved clothes, books and other goods donated by the community in a unique pop-up market.

"There were four local musicians that played at the event and kept the participants entertained while the two stalls [Port Stephens Council and Sea Shelter] attracted plenty of interest," Mr Holliday said.

Port Stephens deputy mayor Sarah Smith, who performed the officially opening, said the council was grateful for the opportunity to do its bit for the environment.

"We're so lucky to live in this beautiful place and we need to be responsible for what we leave behind when we come the beach. It's time to take action and raise awareness about the impact that plastic has in our waterways and marine life, so we can all contribute to a better Port for future generations."

Port Stephens Council made the decision to fund the event as part of its commitment to waste minimisation.
