Sydney beaches affected by mystery tar ball spill

According to the articles, a large number of black pollution balls have washed onto beaches across Sydney, specifically around 2,000 balls. The chemicals that form these balls are similar to those found in cosmetics and cleaning products, but the Environment Protection Authority in New South Wales has stated that they are not harmful to health when left on the sand. However, the cause of the deluge of black balls remains unknown. Beaches such as Bondi were closed due to concerns about the toxicity of the deposits, although investigations are ongoing to determine the source of the pollution. It was also mentioned that swimmers have been cleared to reopen on Saturday, but beachgoers have been asked to report any tar balls they see to lifeguards.
