CATE Campbell’s “fun” event is set to be a keeper on her program after she won gold in the 50m butterfly in an all-Aussie trifecta, one of two produced on the night after Mitch Larkin also led home two compatriots in the 50m backstroke.

Campbell’s post-Olympic soul searching led to her looking to push her comfort zones in and out of the pool and led to her adding the 50m butterfly to her program.

While they are not Olympic events, the 50m form strokes are on the Olympic and world championship programs and as long as she is injury free, Campbell will continue to swim the short-form event.

Campbell led Holly Barratt and Madeline Groves home in a result that thrilled the crowd just minutes after Mitch Larkin, Ben Treffers and Zac Incerti swept the 50m backstroke.

HUGE RESULT: Para swimmers deliver gold, world record

UPSET: Sickness no excuse for King Kyle shock defeat

“I swear, if there was a roof on the stadium, we would have lifted it off,” Campbell said.

Following her post-Olympic sabbatical, Campbell said she wanted to “shake things up this year and try something new and different”.

“I’m lucky that 50m butterfly is in the program and I don’t want people to think I’m taking this lightly, I’m still representing my country,” Campbelll said.

“It is really nice (to have an event with no pressure).

“I’ve been a two-trick pony for my entire career — the 50m and 100m freestyle, it makes a nice change.”

Earlier, Campbell (52.64) zipped through the 100m freestyle semi-final in a new Games record time as fastest qualifier into the final.

Sister Bronte (53.46) and training partner Shayna Jack (53.58) will join her but Campbell’s biggest foe may no longer be out-of-sync Olympic champion Penny Oleksiak but tall fellow Canadian Taylor Ruck (53.05).

Cate Campbell embraces teammate Holly Barratt after victory.

Thirty-year-old Barratt continues to shine after making her senior Australian debut as a mature-age rookie last year.

“Tonight was so much fun and I love this crowd,” she said.

“They are amazing. To come in all three after the boys is great.”

After a horror year in which she fought a possible drug ban and health issues, a healthy and happy Groves has thrived at these Games.

“It’s been an unbelievable week for me,” she said.

“To win two individual medals is so special.

“And two clean sweeps, you could not have picked better.”

Mitch Larkin celebrates winning the men’s 50m backstroke.

Meanwhile, Mitch Larkin can suddenly dream of an attack on four gold medals in the pool after a backstroke revival sparked by the blunt truth delivered by his new coach that he’d over cluttered his head with a search for the perfect stroke.

Last night’s 50m backstroke was a lottery and the tall Brisbane swimmer saluted with the gold medal-winning ticket in 24.68 sec in the least fancied event of his schedule in the Commonwealth Games pool.

It was a soaring moment for Australia’s No. 1 couple of the pool after girlfriend Emily Seebohm had finished strongly for bronze in the 200m backstroke earlier in the night.

Larkin, 24, now has the 50m and 100m golds in his keeping, shoots for the 200m on Monday night and will be an ace for the Aussies in the 4x100m medley relay that closes the hectic swimming program on the Gold Coast tomorrow night.

It was a super trifecta for the Aussies in the 50m splash dash with Canberra-born defending champion Ben Treffers (24.84) swimming his fastest time since 2015 and Perth’s bronze medallist Zac Incerti (25.06) gallantly conquering pre-meet back issues.

“I knew if things went to plan we could go one-two-three with an awesome crowd,” Larkin said.

Larkin, the two-time world champion of 2015, has rediscovered his winning mojo since joining coach Dean Boxall in Brisbane late last year after losing his way like an obsessed golfer searching for technical tweaks in his swing that he didn’t need.

“When I met with Dean to discuss plans about where to head he just said quite plainly I’d been over thinking,” Larkin said of his third coach in that 12-month period.

“He said ‘swim like you’re that teenage boy again, feel the water and just swim.’

“He meant a little more carefree because I’d been picking up things about technique along the way and mixed messages were feeding into my swimming that were my own fault.”

Having Boxall on board has Larkin swimming that bit higher in the water, hips ups, shoulders up, so he’s not pushing mountains of water with his shoulders.
