John Foley, South Australia's celebrated bushranger, led a colourful life that took John Lovett or Lovatt from Suffolk to Sydney as a convict. Then as an escapee he was the first European to walk the South Australian coast between Portland Bay and Encounter Bay. Arrested for horse-stealing, he escaped trial in Adelaide and appeared to become a reformed character. He returned to England in 1840, where he apparently returned to his old ways.
