Protecting Our Waterways
Water quality monitoring along Foreshore Beach is carried out to ensure the waters are safe for swimming. During heavy rain events the waters are often unsuitable for swimming for periods due to sewer overflows. Information and monitoring results can be found at Beachwatch.
Sydney has better marine life than any other city on the planet. From sea dragons to sharks, pufferfish to penguins, Sydney has it all - it is our best kept secret. But discovering it all in person can be a little challenging, and certainly not everyone's cup of tea.
Using specially developed Fisheye Video and Underwater GPS Photography we have found a way to reveal Underwater Sydney - to show you actual creatures in real locations and to give you a unique window into their world.

Botany Bay & Catchment Water Quality Improvement Program
The Greater Sydney Local Land Services has developed and manages the Botany Bay and Catchment Water Quality Improvement Program.
This program aims to achieve long-term protection of the surface waters of Botany Bay, its estuaries and its catchment. It focuses on the pollutants washing off the hard surfaces in the catchment (suspended solids, nitrogen and phosphorus). Local residents and members of the business community in the Botany Bay Catchment are encouraged to participate in implementing innovative solutions to improve water quality in Botany Bay.
Botany Bay is divided into two catchments. Mill Pond Creek and the Cooks River, both of which discharge to Botany Bay.
The Mill Pond Creek Catchment is defined as the area that drains into Botany Bay between Cape Banks and the mouth of the Cooks River. The catchment is approximately 3,586 hectares. Most of the catchment contains piped stormwater channels that convey stormwater from Centennial Park Ponds into the Botany Wetlands and Botany Bay. Centennial Park and Botany Wetlands are the two significant water bodies in the Mill Pond Creek Catchment. The southern part of the catchment contains mainly industrial land.
The Cooks River Catchment is located in the southern suburbs of Sydney and covers an area of 10,000 hectares. The Cooks River originates in Bankstown and flows 23 kilometres east to discharge to Botany Bay just south of the airport. Alexandria Canal is a major tributary of the Cooks River and is located in the City of Botany Bay. It is one of Sydney’s most historic waterways, constructed in the 1890’s.
