Cox, who won the PGA Tour of Australasia's Tour School in early 2013, finished on a four round total of 15 under par, two shots ahead of playing partner Daniel Nisbet.
Starting the final round with a two shot lead, nerves appeared to be getting the better of Cox over the opening nine holes, dropping shots at the second and third holes. It appeared Cox would drop a further shot at the par 5 seventh, before holing his bunker shot to save par. This was the break Cox needed heading into the back nine.
"The opening few holes were very scratchy and I knew I would need to stay patient if I was to turn it around. The lie was great in the bunker and as soon as I executed the shot I knew it had a chance. This was a critical moment in the round and it was instant relief when I saw my ball drop," said Cox.
It didn't take long for Cox to right the ship on the back nine making birdie at 10 and 13 to hold a three shot lead with five holes to play. Further birdies at 14, 15 and 17 saw Cox hold a five shot lead playing the last. Although a double bogey at his final hole was a disappointing way to finish, it didn't dampen the win in anyway.
"It has been a long hard road over the past 18 months, though it is wins like this one here today that makes all the hard work put in over the past few year's worthwhile. It was a little disappointing to finish in the fashion I did , though all of the hard work had been done and it was a great feeling to play the last knowing that barring any mishaps I had the win in the bag."
Nathan Holman, Brendan Smith and New Zealander Jim Cusdin tied for 3rd.
Cox will now direct his attention to the Yeppoon Pro Am being played on Tuesday, before tee it up at the $100,000 Pat O'Driscoll Real Estate/Tropical Auto Group Golf Classic on Thursday. Defending champion Paul Donahoo will be one of 81 professionals competing in this year's Classic.
