Railway and tram workers strike in Sydney, marking the biggest industrial upheaval Australia has seen before or since. Thousands had stopped working, the government recruited volunteers to break the strike some of whom carried arms, unions were de-registered and union leaders charged with conspiracy; a time of violent emotions, state violence and individual acts of violence by and against strikers - it was Sydney, 1917 and to this day, Australia's largest industrial upheaval.
