The makeup of the small, ball-shaped debris that recently washed up in Sydney's Northern Beaches has been revealed, and it's just as gross as the first time.

More balls washed up on several beaches last Wednesday, including Manly, Dee Why, Long Reef, Queenscliff, Freshwater, North and South Curl Curl, North Steyne and North Narrabeen.

The mysterious balls have been appearing across Sydney since the first batch was discovered in October 2024.

The balls that washed up last week were made of faecal matter and E. coli as well as saturated fatty acids, according to the results of testing announced today.

"In addition to the hydrocarbons identified in the preliminary test results last week, the latest results indicate the presence of saturated fatty acids, along with faecal coliforms and E-coli," a council spokesperson said.

"Northern Beaches Council is hoping that the EPA analysis will identify the source so that they can stop this from happening at other beaches."

"We are continuing to conduct regular inspections of our beaches and encourage the community to report any sightings."

Northern Beaches Council also said others had washed up over the weekend.

"A small number of marble-sized balls mixed in with pumice have also been cleaned up from harbour beaches this week including at Little Manly and West Esplanade, and Council continues to monitor and clean up as needed."

The council also said several beaches in its LGA are closed today due to hazardous surf, not debris.
