Paul Ellis, marine debris and ghost net coordinator at Dhimurru Aboriginal Corporation, said the language on the packaging and a barcode reader suggested most of the rubbish came from Indonesia.
The waste included discarded fishing gear, syringes, plastic bottles, thongs, bits of foam and an increasing amount of smaller fragments and microplastics.
It is nesting season for hawksbill and green turtles, Ellis said, and cleaning the beach made it more likely the creatures would climb up the sand to lay eggs.
“It’s devastating because it keeps washing up and it seems never-ending, but what keeps us going is that we see the benefit of cleaning the beaches,” Ellis said.
“We’ll clean a section of beach and then the next morning we’ll wake up and we’ll see fresh turtle tracks in the clean sand, so that’s an inspiration to keep going.”
Cip Hamilton, plastics campaign manager at the Australian Marine Conservation Society (ACMS), said it was important to recognise Australia’s role in plastic pollution – 145,000 tonnes of plastic leaks into the environment every year from domestic sources.
The Australian government has opened a consultation on options for plastic packaging reform to close at the end of October.
Halfway around the world, the state of California is suing ExxonMobil, claiming the oil giant deliberately misled the public for decades about the limitations of plastic recycling. A coalition of environmental groups including the Sierra Club has filed a similar lawsuit.
California Attorney-General Rob Bonta said last Monday the lawsuit came after a nearly two-year investigation, including seeking information on Exxon’s promotion of its “advanced recycling” technology.
“Today’s lawsuit shows the fullest picture to date of ExxonMobil’s decades-long deception and we are asking the court to hold ExxonMobil fully accountable for its role in actively creating and exacerbating the plastics pollution crisis through its campaign of deception,” Bonta said.
California is also suing the oil industry over allegedly misleading the public about climate change.
Exxon pushed back, arguing advanced recycling and similar solutions work and that the state failed to correct problems in its recycling system.
“Instead of suing us they could have worked with us to fix the problem and keep plastic out of landfills,” a company spokesperson said.
Exxon was identified as the world’s largest producer of resins used for single-use plastics in a report published last year by the Minderoo Foundation, the philanthropic venture of Australian billionaire Andrew “Twiggy” Forrest.
The Minderoo Foundation has also funded scientific research into how plastics harm human health.
California’s lawsuit comes ahead of a final round of global plastic treaty negotiations set to take place in Busan, South Korea, at the end of the year.
Countries are split over whether the treaty should call for caps on plastic production, a position opposed by Exxon and the global petrochemical industry. Australia is part of a so-called “coalition of high-ambition countries” pushing for tough action.

Hamilton from ACMS, who will attend the Busan talks with some of the Dhimurru rangers, said she would like to see the high-ambition coalition go further and push for production targets.
“We’re advocating for strong treaty text that tackles the root of the problem, and that’s our over-reliance and overconsumption of needless plastics,” Hamilton said.
