With rounds of 69, 70, 68 and 69, Jordan Spieth finished regulation play tied with Queenslander Cameron Smith and Victorian Ashley Hall on 12-under 276.
It took just one trip down the 18th for Spieth to be pronounced the champion. He birdied the first playoff hole with the Australian duo unable to match him.
This becomes Spieth's second Emirates Australian Open title after he won in 2014 at The Australian Golf Club.
That win teed off Spieth's phenomenal 2015 season which saw him win two Major Championships.
While Smith and Hall were disappointed not to be hoisting the trophy they have been consoled with starts at The Open at Royal Birkdale Golf Club next year.
Joining them at the 146th Open will be Aaron Baddeley who received the final exemption after he finished tied 4th on 10-under the card alongside Jason Scrivener, Rod Pampling, Ryan Fox and Geoff Ogilvy.
Baddeley was provided the place by virtue of being ranked highest in the Official World Golf Rankings.
More to come.
