Coogee Tops Sydney's Worst Ocean Beach for Faecal Pollution 2026

Coogee has again ranked as Sydney's worst ocean beach for faecal pollution, according to the 2026 State of the Beaches report. The annual survey by the NSW environment department found that Coogee's microbial water quality remains susceptible to faecal contamination, particularly after rainfall. This marks the second consecutive year that Coogee has received a "poor" rating, highlighting ongoing challenges with stormwater and sewage overflow.

Understanding the State of the Beaches Report

The 2026 State of the Beaches report assessed 245 swimming sites across New South Wales. Of these, 43 sites (17.6%) received a rating of "poor" or "very poor." While 97% of ocean beaches achieved "good" or "very good" ratings, Coogee stands out as a persistent problem area. The report grades sites based on microbial water quality, with "poor" indicating that pollution is likely, especially after rain.

Why Coogee Beach Is Prone to Pollution

Coogee's steep catchment area means that when it rains, runoff rapidly flows into the stormwater system and directly onto the beach. This runoff carries bacterial pollution from various sources, including dog waste, bird droppings, and sewage overflows. Sydney's aging sewer system is designed to overflow during heavy rain, discharging into stormwater drains that empty into the ocean. As a result, faecal contamination is a recurring issue.

Sources of Faecal Pollution at Coogee

• Stormwater runoff: Washes pollutants from streets and roofs into the sea.
• Sewage overflows: Heavy rain overwhelms sewers, causing untreated sewage to enter stormwater drains.
• Animal waste: Dog poo and bird droppings contribute to bacterial load.
• Steep terrain: Coogee's topography accelerates runoff, reducing natural filtration.

Comparing Coogee to Other Sydney Beaches

While Coogee struggles with pollution, many other Sydney beaches perform well. The table below compares key beaches based on their 2026 ratings.

Health Risks of Swimming in Polluted Water

Faecal pollution can cause gastrointestinal illnesses, skin infections, and respiratory issues. Swimmers are advised to avoid entering the water for at least 24 hours after heavy rain, especially at beaches like Coogee. Symptoms can include diarrhea, vomiting, and ear infections. Vulnerable groups, such as children and the elderly, are at higher risk.

What Is Being Done to Improve Water Quality?

The NSW government and local councils are investing in infrastructure to reduce stormwater and sewage overflows. Projects include upgrading sewer systems, installing retention basins, and public education campaigns. However, experts like Prof Stuart Khan note that climate change may exacerbate the problem, with more intense rainfall events expected.

Key Takeaways for Beachgoers

• Check the latest State of the Beaches report before swimming.
• Avoid swimming at Coogee for 24-48 hours after rain.
• Be aware that stormwater pollution can occur even in dry weather.
• Support initiatives to improve water quality and infrastructure.
