 Tom Clarke, 27, and his brother John, 21, were hanged from twin gallows at Darlinghurst Jail on 25 June 1867, ending a reign of terror on the south coast of New South Wales which had cost the lives of at least eight men who were mainly police trying to capture the brothers.The Clarkes and other bushrangers may have had some influence in Parkes's campaign for educational reforms.In his electioneering speeches of 1867 he spoke of the Clarkes and the necessity of schools in the outback as a way of putting down bushranging.
