ROBYN WUTH | GoldCoast.com.au
The businessman, who famously repossessed everything from cruise ships to skyscrapers, was shot in what was believed to be a botched robbery in the dangerous town.
It is understood Mr Purdy died instantly.
The Australian Department of Foreign Affairs confirmed the death of a 62-year-old man in Papua New Guinea.
Friends yesterday confirmed Mr Purdy's death but declined to comment.
Mr Purdy was well known on the Gold Coast and operated a towing business, Cobra Towing, for more than 20 years.
His other enterprises included an equipment import-export business which targeted small countries with troubled economies, car yards, a repossession business and experimentation with the manufacturing of table tops from broken glass.
Mr Purdy had been working in construction in the Mt Hagen area.
Numerous travel warnings have been issued for the area due to the high level of serious crime.
Local authorities warned of a "heightened risk" of armed robbery and attack.
