NSW’s 2026 Beach-Water Quality Report Shows Broad Gains, but Local Hotspots Remain

Statewide Improvements Highlighted in the 2026 Report
The State of the Beaches report released on September 24, 2026 recorded an overall rise in water quality across New South Wales. Seventy-nine percent of the state’s waterways earned a “good” or “very good” rating, and 97 percent of ocean beaches met the same standards, qualifying them for swimming most of the time. The NSW government linked these gains to drier weather during the reporting period, which curtailed storm-water runoff and lowered pollutant loads.
Sydney’s Beach Rankings: Winners and Losers
Avalon Beach was singled out as Sydney’s cleanest ocean beach for 2026, sharing the “equal-cleanest” title with several coastal sites in the Central Coast, Illawarra, Hunter and Shoalhaven regions. The proportion of Sydney Harbour beaches in the top tier rose from 78 percent to 81 percent. In contrast, Coogee, Rose Bay and numerous Botany Bay locations received a “poor” rating for the fifth consecutive year, reflecting persistent storm-water impacts. Two sites were classified as “very poor”: Foreshores Beach, adjacent to Sydney Airport and long-noted on social media for mercury, phosphate and dog-dropping contamination, and the Gymea Bay baths, which also performed poorly last year.
Drivers Behind the Shifts
Beyond weather, the NSW government noted that the share of estuaries, lakes and lagoons rated “good” or “very good” climbed from 63 percent to 69 percent. These inland water bodies typically record lower scores than open-ocean beaches, so their improvement contributed to the statewide uplift. Environment Minister Penny Sharpe emphasized that the long-term monitoring program Beachwatch supplies robust data, enabling authorities to track trends and inform water-quality decisions.
Practical Advice for Swimmers
Officials continue to urge the public to consult the Beachwatch website before entering the water, especially at sites with historically poor ratings. While many Sydney beaches now meet “good” standards, localized issues persist, and checking real-time data remains the safest approach for swimmers.
