The Australian ended up in a tie for fourth on 288 with first-round leader Lee Slattery (76) and his fellow Englishman MarcusHigley (77), American Nathan Smith (71), Denmark's Jacob Olesen (68) and Martin Erlandsson of Sweden (76).
The 28-year-old from Belfast proved a class apart as he topped the leaderboard ahead of Scotland's Richie Ramsay, France's Raphael Jacquelin and England's MarcusHigley -- while American John Daly would have been joint second as well but for two closing bogeys.
