Jervis Bay is in the south coast region of New South Wales. It is a large oceanic bay with an open entrance.
Jervis Bay is a popular tourist destination on NSW south coast. It boasts powder-white sands, crystal clear waters, extensive areas of intact native vegetation and plenty of opportunities for recreational activities, including diving, snorkelling, boating, fishing and whale watching.
The area has significant Aboriginal cultural and heritage value, including the Booderee National Park, which is managed by the Wreck Bay Aboriginal community in collaboration with Parks Australia.
Jervis Bay is also home to one of Australia’s largest commercial mussel-growing leases.
Currambene Creek was last sampled in 2017–18 with the other tributaries last sampled in 2011–12.
As part of our Beachwatch program we assess swimming suitability at one swimming site in Jervis Bay using microbial indicators. Shoalhaven City Council collect samples at each site weekly between December and February to calculate the suitability grade. Sampling is ongoing. The grade reflects the most recent 56 water quality results to February 2021. Find out more about how we monitor beach water quality(link is external).

Very good
Collingwood Beach usually has excellent microbial water quality. It has few potential sources of faecal pollution and water is considered suitable for swimming almost all of the time.
Water can sometimes be unsuitable for swimming, especially after rainfall, when stormwater and wastewater can overflow into swimming areas. Learn more about what the grades mean and how we grade swimming sites on the Beachwatch How we report(link is external) webpage.
Water sampling and laboratory analysis were funded by Shoalhaven City Council.

The Jervis Bay catchment has a low level of disturbance, with large forested areas conserved by national parks. A number of low- to medium-density residential areas and associated amenities occur along the coastline. Over time the area has supported an array of industries, including grazing, dairy farms, fishing, timber extraction, ship building, whaling, naval training and tourism.
Local councils manage estuaries within their area unless the estuary is attached to a marine park. This estuary is located within the Jervis Bay Marine Park and is managed by Shoalhaven City Council(link is external).
