The 35-year-old had extended a two-shot lead to three on day two and he doubled his advantage with a third-round 65 on Saturday to put himself in pole position for a second victory on the DP World Tour.

Fox was at 19-under, with Scotland's Scott Jamieson among the group at 13-under after a 65 of his own.

Australia's challenge is being led by Jason Scrivener, who's eight off the pace in joint-ninth place at 11-under after a 70 which began spectacularly when he holed out from 105 metres for an eagle two and moved briefly to within a shot of Fox.

"Somebody is going to have to go out and shoot something really low or I'm going to have to play poorly so hopefully I can keep playing how I've played the last couple of days and put it out of reach." - Ryan Fox.

Scrivener's fellow Aussies Wade Ormsby and Maverick Antcliff are both on seven-under after shooting 72s.

Fox's previous win on a top-tier Tour came at the World Super 6 Perth – an event combining strokeplay and match play – in 2019, and he was fully aware the expectation would be on him as he seeks a win in 72-hole strokeplay.

"I've put myself exactly where I want to be and it's that cliche – it's all on me tomorrow," he said.

"Somebody is going to have to go out and shoot something really low or I'm going to have to play poorly so hopefully I can keep playing how I've played the last couple of days and put it out of reach.

"For the most part everything has worked – which is kind of rare for me, to be honest, I've always had something for the week that hasn't worked. Hopefully I can keep that going for one more day."

Fox made nine birdies and two bogeys in round three, while Jamieson was bogey-free as he continued the form that has put him in the top-20 of the early season Tour rankings.

Spanish duo Adri Arnaus and Pablo Larrazabal and Pole Adrian Meronk were alongside Jamieson at 13-under, one clear of Scot Robert MacIntyre.
