Georges River Council was proclaimed on 12 May 2016, with the first meeting held at Kogarah Civic Centre on 19 May 2016.

A 2015 review of local government boundaries by the NSW Government Independent Pricing and Regulatory Tribunal recommended that Kogarah City Council and Hurstville City Council amalgamate to form a new council with an area of 38 square kilometres and support a population of approximately 147,000.

In May 2016, the NSW Government through its ‘Fit for the Future’ local government reforms then amalgamated the former Kogarah City and Hurstville City Councils to create Georges River Council. To assist with the transition of the new Council Mr John Rayner PSM was appointed as Administrator of the organisation.

The first meeting of the Georges River Council was held at Kogarah Civic Centre on 19 May 2016.

The first Georges River Council local government elections were held on 9 September 2017 where 15 Councillors were elected across five wards. Councillor Kevin Greene of the Peakhurst Ward was nominated as the first Mayor of the new Council, while Councillor Kathryn Landsberry of the Blakehurst Ward was nominated as Deputy Mayor.

Georges River Council is now delivering numerous benefits and services to members of the local community and is planning for the future.
