An Australian beach volleyball pair triumphed on the sand while the nation's oldest competitor at the Commonwealth Games says a fluke shot on the green turned into gold on Thursday.
The host nation extended its lead atop the Gold Coast Games' medal tally, collecting two more gold in early action on Thursday.
As it emerged three doped locals were barred from competing on the Gold Coast, Australia's men's beach volleyball pair Chris McHugh and Damien Schumann downed Canadian opponents in the gold medal game.
And para lawn bowler Ken Hanson, aged 68, helped form a victorious triples opens with a disability team.
Hanson and teammates Josh Thornton, Tony Bonnell stole the gold from under New Zealand noses in Thursday's B6/B7/B8 final.
With the last bowl of the medal match and Australia trailing, Hanson blasted two New Zealand balls away from the jack with a perfect draw shot to pinch victory.
"It was just to let it go as hard as I could and hope I hit the right ball, which it did," Hanson said.
Ahead of Thursday night's competition, Australia has 58 gold medals for the Games - next-best is England (26) and India (12).
As the host nation's golden Games continued, it was revealed three Australians had been blocked from competing for doping.
Australian Sports Anti-Doping Authority chief executive David Sharpe said the Australians, who he refused to identify, were among a number of international athletes targeted for pre-Games testing.
"It's about taking those cheats out before they arrive at the Games," Sharpe told reporters on Thursday.
Also on Thursday, Australian 100m hurdlers Michelle Jenneke and Brianna Beahan advanced into Friday night's medal race.
Jenneke performed her customary pre-race jiggle despite hoping to keep a lower profile after criticism of her 2016 Rio Olympics when she bombed out in the heats.
"After Rio I got a little bit slammed by the media and it hurt a little bit, so this time I was just trying to stay out of it, do my work," Jenneke said after clocking 12.99 seconds, a season-best.
Australia has three men in Friday night's discus final after Matt Denny, already a hammer throw silver medallist, reigning Commonwealth champion Benn Harradine and Mitchell Cooper advanced through Thursday's preliminary round.
Also into a final is diver Melissa Wu, who shunned wind worries at the outdoor aquatics centre to book a berth in Thursday night's 10m platform diving medal competition alongside compatriots Brittany O'Brien and Teju Williamson.
The 10m platform has been dubbed the Tower of Terror because strong winds have spooked some divers - but not Wu.
"You have to do what you have to do - just get out there and dive," she said.
Australia's men's divers James Connor and Games debutant Matthew Carter also secured spots in Thursday night's 3m springboard final.
Meanwhile, Australia's mountain biking couple Rebecca McConnell (sixth) and Daniel McConnell (seventh) missed the medals in their cross country races at Nerang.
And Australian rhythmic gymnasts Enid Sung (fourth) and 16-year-old Alexandra Kiroi-Bogatyreva (10th) fell short in the individual all-around finals.
