Usually referred to as the "New South Wales General Strike", but referred to by contemporaries as "the Great Strike", it was in fact neither general nor confined to NSW. The strike was however a mass strike, involving around 100,000 workers, mostly in NSW and Victoria. It began in the Australian state of New South Wales and spread to other states over six weeks from 2 August to 8 September 1917 when the official leadership declared the strike over. It took two weeks for all the railway strikers to return, however, as rank and file meetings initially rejected the official capitulation. Outside the railways, significant groups such as the waterside workers in Sydney and Melbourne, and the Hunter Valley coal mines remained out until November (or December in the case of the Melbourne waterfront) as in their case the use of strikebreakers had turned the strike into a lockout.
