The latest State of the Beaches report has revealed 94 per cent of monitored ocean beaches and 80 per cent of all monitored swimming spots are graded as good or very good.
The annual report provides an overview of water quality at 214 swimming locations across the State, which are monitored under the NSW Government's Beachwatch and Beachwatch Partnership programs.
Minister for Environment James Griffin said State of the Beaches has five categories of water quality rating: very good, good, fair, poor or very poor.
"Despite the wettest summer in a decade, and Sydney's wettest year on record, there's been only a slight decline on last year's results," Mr Griffin said.
"In 2021-22, 172 (80 per cent) of the 214 swimming sites in NSW were graded as good or very good, indicating they were suitable for swimming most of the time.
"With more than 85 per cent of people in NSW living within 50 kilometres of the coast, heading to a local swimming spot is a way of life for many of us.
"We've been running the Beachwatch monitoring program since 1989, and we know how important it is for providing confidence to the people of NSW, which is why we announced in the NSW Budget that we're expanding the Beachwatch Partnership program with $18.5 million over 10 years."
Rainfall is the major driver of pollution in recreational waters, as it generates storm water runoff and triggers discharges from wastewater treatment systems.
Many estuarine, lake and lagoon swimming sites did not perform as well as ocean beaches as they are more susceptible to wet weather impacts.
State of the Beaches 2021-22 found:
- 94 per cent of the 123 ocean beaches were graded as 'good' or 'very good'
- all five ocean baths were graded as 'good' or 'very good'
- 68 per cent of the 69 estuarine swimming sites were graded as 'good' or 'very good'
- 24 per cent of the 17 lake/lagoon swimming sites were graded as 'good' or 'very good'.
The Beachwatch program works by routinely collecting water from swimming sites and testing for bacteria as an indicator of contamination.
Beachwatch also issues daily early morning forecasts for the predicted water quality at 160 swim site in Sydney, Hunter, Central Coast and Illawarra regions.
