The council was amalgamated, along with most of its neighbours, with the City of Sydney to the north with the passing of the Local Government (Areas) Act 1948.

[2] On 19 July 1872, the first council, consisting of six aldermen in one electorate, was elected (Charles Brandling Henderson, Henry Knight, James Bryan, Alexander Swanson, William Irwin and James Heighington), with Henry Knight elected as the first mayor at the first meeting on 23 July 1872.

On 1 December 1937, the Mayor of the council, Alderman J. W. Elliott, laid the foundation stone and nearly year later, on 26 November 1938, the Secretary for Public Works and Minister for Local Government, Eric Spooner MLA, officially opened Erskineville Town Hall with the Mayor at that time, Alderman Nicholas McGuinness.

[12] By the end of the Second World War, the NSW Government had realised that its ideas of infrastructure expansion could not be effected by the present system of the mostly-poor inner-city municipal councils and the Minister for Local Government, Joseph Cahill, passed a bill in 1948 that abolished a significant number of those councils.

Under the Local Government (Areas) Act 1948, Erskineville Municipal Council was merged with the larger neighbouring City of Sydney.
