"I think, especially with the form in the last few weeks from some of the boys, Hendry, Mark Brown and Paddison playing well, they're a good chance this year, for sure."
As for his own form, Geary said despite having a lean year in the United States where he struggled to get starts after missing a few cuts early in the season, he felt like he could be in contention.
"This year I haven't played more than two [tournaments] in a row but it's just not me. I need a bit of momentum going on and what not. I think most guys do."
Geary has suffered plenty of disappointment in recent weeks after failed attempts to qualify for next year's European and PGA Tours.
He holds no status in the US next season and hoped a couple of big performances in New Zealand and Australia during the next few weeks would see him earn an opportunity to play in Asia next year.
Geary finished third at Clearwater last year and if he could go two better this week he would break a lengthy drought in New Zealand sport and breathe life into his own career.
Hendry is the leading money-winner on the Australian PGA Tour in 2012 and said he felt in good touch.
Peter O'Malley is one of the Australians who will want to steal the crown and he has won at Clearwater before.
"I like this golf course. It's in very good shape."
Nick Cullen, Aaron Townsend and amateur Jake Higginbottom are the other Aussie raiders who could spoil the party this week.
