Spark's favourite residence was his farm at Cooks River however in 1829 he was at the Hunter Valley property when it was robbed by bushrangers Richard Brown, Patrick Corcoran, Richard Turnstyle and Andrew Cullen. In an attempt to keep the bushrangers at bay, he fired through the door at them.  The bushrangers were later captured and executed at Maitland.
