The New Zealander earned his maiden European Tour title in 2019, winning the ISPS Handa World Super 6 Perth back in February after recording a convincing 3&2 victory over Adrian Otaegui in the final.
But he struggled for form after that, failing to secure another top 30 finish until the 148th Open Championship at Royal Portrush Golf Club, where he finished in a tie for 16th.
Low scores continued to evade Fox when he returned to action in September, with missed cuts at the Omega European Masters and the BMW PGA Championship sandwiching a joint-60th finish at the Porsche European Open.
But he began to turn things around at the Alfred Dunhill Links Championship, where he shot a confidence-boosting 64 in the opening round.
That was followed by top 20 finishes at the Italian Open and the Amundi Open de France in October and further impressive displays in Portugal and Turkey.
Fox said: “It has been a much nicer end to the year.
“If you take The Open out at Portrush, it was a very lean patch in the middle.
“I was pretty desperate there for a while, even when I came back from a break after the Open it was still a bit of a struggle.
“It was nice to find a bit of form in the back part of the season.
“The Dunhill Links was the start of it for me, shooting a 64 in the first round – even though I didn’t finish it off - it was the start of feeling better on the golf course.
“Although I haven’t quite put it together, the last six or eight events there’s been some much better golf and a lot of positives to take out of that.”
The 32-year-old is among a strong field gathered at RACV Royal Pines Resort for this week’s event, with two-time defending champion Cameron Smith and Major winner Adam Scott also present.
Fox will play his opening two rounds alongside Smith and American Cameron Champ and he is well aware of their considerable talents.
He added: “I’m going to have a short game clinic from Cam Smith and a ball-striking clinic from Cam Champ – it’ll be an interesting couple of days for sure.
“There’s a lot to play for this week.
“It’s a course I’ve played a lot, I know it fairly well and have had a couple of decent results in the past – so I’m looking forward to a good week.” European Tour
