With one shot, Craig Douglass hit the jackpot at Redcliffe Golf Club.
The 55-year-old scored a hole-in-one on the 11th green to win $10,000 put up by Shield St Eats, at Prince Edward Pde, Redcliffe.
Remarkably, after 95 weeks without an ace on the par three hole, club member Annette Brown did the same three days later.
However, the sponsorship - which increases $100 each week without an ace on the 11th in competitions - had gone back to its starting point of $500.
An estimated 75,000 players had a chance of winning the Shield St Eats prize in almost two years between holes-in-one on the 11th, which is thought to be a record.
Mr Douglass, from Strathpine, who plays off a handicap of 9, has had three previous holes-in-one during the 45 years he has been playing golf.
But none had $10,000 resting on them.
"I said to my wife I was going to get the hole-in-one … and she laughed," he said, "maybe that's the power of positive thinking!”
Mr Douglass used a six iron from the 154m men’s tee, landing the ball in the middle of the green but was not convinced it had gone in the hole.
“I thought it was in, but one of the guys I was playing with thought it went over the back (of the green),” he said.
“I couldn't bring myself to look in the hole. I got one of the other guys to do it!
“I was pinching myself the rest of the day making sure it had actually happened!”
Annette Brown, an A Grade player with a handicap of 11, had no concerns over her hole-in-one, hitting a five iron perfectly and watching it go in.
A member at Redcliffe for 20 years, it was the second hole-in-one of Ms Brown’s career.
The sponsorship rules are a hole-in-one has to be scored by a player with a Golf Australia handicap in Redcliffe’s Tuesday and Thursday Ladies’ or club Wednesday and Saturday competition.
Mr Douglass, who moved up from Canberra in 2018, had breakfast at Shield St Eats before playing in the following Saturday competition at Redcliffe Golf Club.
