Avalon beach in Sydney was named the city’s cleanest for 2026, while Coogee Beach received a fifth consecutive “poor” grade due to stormwater impact. Ninety-seven percent of monitored ocean beaches across New South Wales were rated as "good" or "very good," marking an improvement from the previous year's 95%. Dr. Meredith Campey, manager of NSW’s Beachwatch program, attributed the better water quality partly to below-average rainfall in many parts of the state during the reporting period.

Story summary
In 2026, the State of the Beaches report named Avalon on Sydney's northern beaches as one of the cleanest in New South Wales, alongside Birdie Beach, Frazer Beach, and Forresters Beach on the Central Coast. Ninety-seven percent of monitored ocean beaches received "good" or "very good" ratings, an improvement from previous years. However, Coogee Beach received a "poor" grade for the fifth consecutive year due to stormwater impacts. Dr Meredith Campey suggested that stormwater drains, sewage outflow points, and swimmers could contribute to water quality risks. Despite this, only two sites in Sydney were deemed “very poor,” including Foreshores beach near Sydney airport and Gymea Bay baths.

In short:
Sydney's cleanest beaches have been named, with one popular spot receiving a "poor" grade for a fifth year running.

Coogee Beach received the rating as one expert blamed its susceptibility to stormwater impacts.
Avalon, on Sydney's northern beaches, was named the cleanest in the city for 2026.

Avalon → receive → 2026
Water quality at the state's beaches has improved slightly, but one of Sydney's most popular swimming spots has received a "poor" grade for the fifth year in a row.

Ninety seven per cent of the state's monitored ocean beaches received a rating of "good" or "very good" in this year's State of the Beaches report, up from 95 per cent in 2025.
asserted

Avalon was Sydney's cleanest beach, while on the Central Coast, Birdie Beach, Frazer Beach and Forresters Beach shared top honours.

One Mile Beach was the Hunter's highest-scoring swimming spot, while the Shoalhaven's cleanest was Warrain Beach.
Wollongong City Beach and Shellharbour Beach were the Illawarra's cleanest beaches in 2026.
However, the report also highlighted continued water quality issues at some swimming spots, including Coogee Beach, which received another "poor" rating.

Dr Meredith Campey, manager of the NSW government's Beachwatch program, said Coogee was "more susceptible to stormwater impact" than other beaches.
asserted
Coogee → say → beaches
"In dry conditions, it's usually suitable for swimming,"Dr Campey said.
"But when it rains, it gets a lot of stormwater which comes through a large stormwater drain at the north end of the beach," she said.
asserted
she → say → beach
Narrabeen Lagoon, Rose Bay Beach, Frenchmans Bay and Yarra Bay were among the 40 sites to receive "poor" grades.
asserted
Lagoon → receive → grades
Foreshores Beach, Gymea Bay Baths and the Blue Mountain's Minnehaha Falls all received "very poor" grades.

Beachwatch did not assess every swimming spot, but graded 229 sites on a scale from "very good" to "very poor."
asserted
Beachwatch → assess → poor
As well as ocean beaches, they included estuarine, lake, lagoon and freshwater sites.
asserted
they → include → sites
The sites were given a sanitary inspection to assess the likelihood of faecal contamination.
asserted

Stormwater drains, sewage outflow points and swimmers themselves could all contribute that risk, Dr Campey said.

Campey → contribute → risk
Regular water quality testing was also undertaken, measuring the levels of enterococci — a bacteria found in faeces.
asserted
testing → undertake → faeces
Overall, 79 per cent of swimming spots received "good" or "very good" gradings, a slight improvement on last year's result of 76 per cent.

Dr Campey said many parts of the state received average to below-average rainfall during the 2026 reporting period, which had a positive effect on water quality results.
asserted
which → say → results
"Rainfall is the major driver of pollution to recreational waters, because it generates stormwater runoff and also triggers discharges from the wastewater system," she said.
asserted
she → generate → system
While the blue water and golden sand of Bondi Beach are internationally recognised, the report shows 'Pondi' — Penrith Beach — enjoys the same "good" grade as the famous landmark.
