Allenby, the Australian Open winner last week at Moonah Links, completed the third round with an 8-under 64 on Sunday morning and closed with a 67 for an 18-under 270 total on the Coolum Resort course. He also in 2000 and 2001 at Royal Queensland.
On the par-4 18th, Allenby hit an 8-iron shot to 3 feet to set up his winning putt.
'As soon as I hit it I knew it was perfect,' Allenby said.
Goggin finished with a 63, matching the course record.
