They were first spotted by a member of the public on North Shelly dog beach last week.

"Council confirmed the presence of debris balls and advised that all visible balls were cleared from the beach by mid-afternoon," said a council spokesman.

"Debris balls washed ashore could be from a variety of sources or locations such as storm water, sewerage networks, ships from local or international locations.""Further inspections and safe clean-up are under way."

In the meantime, the general public have been advised not to touch or go near the balls.

The incident echoes the discovery of thousands of small spheres along Australia's New South Wales coastline both in 2024 and again earlier this year when multiple beaches had to be closed.

It was later determined that the balls in the latter case were from a sewage spill.
