Richardson claimed a one shot victory, after closing with an even par round of 72 to finish at four under, one shot ahead of NSW's Sam Brazel and New Zealander Jared Pender. Pender came close to spoiling the party for Richardson, shooting a five under par 67, though a bogey five at the par four 17th would prove to be costly in the end.
The leaderboard changed throughout the day, though it would be an up and down for par from 60 metres out on the par four 16th hole that would keep Richardson's momentum going. A regulation par at the 17th and a two putt par at the last would see Richardson claim the largest tournament of his young professional career.
"This is no doubt the biggest win of my career, a win that I have been dreaming about for the past 12 months," Richardson said.
"Patience was certainly the key this week around the Royal Port Moresby Golf Course, a course that can really penalise a poor shot. The timing of this win couldn't have been better, as I will take the confidence I have gained from my win here into the remainder of the Asian Tour events throughout the year."
With the South Pacific Export Papua New Guinea Open celebrating its 20th anniversary, Tournament Director Andy Stocks was delighted with the success of this year's event. "The National Open is a significant event on the sporting calendar and we are once again delighted with the event we have delivered this year. The support that we generate from hosting is nothing short of astonishing, and I am sure all the sponsors and spectators will walk away from this year's Championship proud of their investment of golf in Papua New Guinea."
After two long weeks in Papua New Guinea, professionals will now enjoy a couple of days break. Professionals will then be back in their cars, as the Queensland Sunshine Tour heads north for the 2014 PCR Polyweld Mining Town Series.
