Formed in 1973, the Western Sydney Regional Organisation of Councils (WSROC) is a membership organisation that represents five local councils in the Greater Western Sydney region, including Blacktown City Council, Blue Mountains City Council, Hawkesbury City Council, and Liverpool City Council.

With a reputation for considered policy analysis and bipartisan advocacy, WSROC brings a collective voice to those issues which are crucial for Greater Western Sydney's growing population.  

WSROC's primary role is to represent the councils and communities of Greater Western Sydney, as well as developing resource sharing and other co-operative projects between member councils. WSROC also manages a number of projects, which are either funded jointly by its members or from external sources. 

Our current projects include:

• Western Sydney Energy Program (WSEP) The Western Sydney Energy Program is a collaboration between nine councils that aims to realise energy, cost and emission savings for Western Sydney councils and their communities.

• Western Sydney Regional Waste Avoidance and Recovery Strategy 2014 - 2021 Developed by nine participating councils and funded by the NSW EPA, the Regional Waste Strategy is a blueprint for strategic, collaborative action on waste management in the Western Sydney region.
  
  
  
• Turn Down the Heat Strategy and Action Plan 2018 – 2021 Turn Down the Heat is a WSROC-led initiative that takes a collaborative, multi-sector approach to tackling urban heat in Western Sydney. Developed with the input of 55 different organisations, the Strategy lays out a five-year plan for a cooler, more liveable and resilient future.
  
  

• An independent technical review of the Western Sydney Airport draft EIS Jointly funded by 11 Greater Western Sydney councils.
