A group of 21 volunteers has removed 66,752 pieces of rubbish from remote beaches in Tasmania's World Heritage Area.
Team Clean spent nine days on three commercial fishing boats cleaning beaches on the state's South-West coast.
The non-profit group has been taking expeditions to clean up World Heritage beaches since 1999.
Team Clean coordinator Matt Dell said this year was more challenging than usual with rough weather conditions making half the crew seasick.
"We averaged 16 people on the beach every time we went ashore and we spent between four and eight hours a day picking up the rubbish and then a couple of hours an evening counting it and itemising it," Mr Dell said.
Mr Dell said the group had been returning to the same beaches for 21 years and over this time they had been collecting less and less big items, like ropes or nets, but continued to collect thousands of micro-plastics.
"One day we picked up 12,000 small bits of plastic off a 50 metre long beach," Mr Dell said.
Mr Dell said he wanted to thank the commercial fisherman who donated their time to make the trip possible and the group's sponsors.
"They are doing it pretty tough at the moment and one of the fishermen hadn't been working for three months," he said.
"It's actually quite rugged and raw around there and we need pretty specialised skilled skippers and dingy drivers to get us onto the beaches to do the work."
