C2Source - Curly Community Cleanup Crew
C2Source (Sea to source) is an environmental action organisation that looks at the health of the whole of the catchment from the Source to the sea for river systems.
Curly Community Cleanup Crew (CCCC) is made up of people (like you) that are concerned with the health of the Brookvale, Curl Curl environment.
CCCC comes together a few times a year to remove single-use plastic and other waste from the system starting from the Source of the Greendale Creek, through Curl Curl Lagoon to Curl Curl Beach.
Greendale Creek
Greendale Creek rises in the hill behind the 'Brickworks' in Brookvale as shown below, goes underground before it gets to St Augustine's school, continuing under Brookvale Oval. Passing under Pittwater and Windbourne roads briefly reemerging briefly by Curl Curl/Brookvale Scout Hall. Going under Windbourne Estate the creek reappears just before Harbord Road it then runs through John Fisher Park and flows into Curl Curl Lagoon.
