Australia’s team of world-class swimmers are well on their way to making Commonwealth Games history.

Having already won 16 gold medals across the first three days of the Games, the Dolphins elevated to a new level overnight by claiming another seven on the fourth.

Of the nine finals staged in the night session at the Tollcross International Swimming Centre, Australians emerged victorious in seven.

There were also two clean sweeps of the podium — including Meg Harris defying outsider status to defeat compatriots Mollie O’Callaghan and Shayna Jack in the women’s 100m freestyle final.

The night was bookended by Jenna Forrester claiming her second gold medal of the games with a 4min31.19sec effort in the women’s 400m individual medley and the women’s 4x200m freestyle relay team cruising to victory in 7:42.53.

In between, Harris (52.90sec) stunned O’Callaghan and Jack, 17-year-old Beau Matthews (1:09.41) won the men’s 100m breaststroke S9, Alex Perkins (56.38sec) dominated the 100m butterfly, Sam Williamson (26.50) continued an unbelievable comeback from injury in the men’s 50m breaststroke and the dominant Sam Short (7:39.81) was way too good in the men’s 800m freestyle.

With another 19 deciders still to be held across the final two days of swimming in Glasgow, Australia appear well and truly on their way to breaking the record of 28 swimming gold medals at a single Commonwealth Games they set on the Gold Coast in 2018.

The most remarkable victory of the night belonged to Harris, a noted 50m specialist who was swimming an individual 100m final for the very first time at a senior international event.

Speaking with Channel Seven after the race, Harris said competing at the distance was “always fun” — before quickly correcting herself in noting her limited experience.

“I knew I had to go out hard, Mollie always mows me down. I was hoping, just for once, I’d be able to hold her off,” Harris joked.

“I’ve learnt so much along this journey. As the week’s gone on, I’ve learnt more about my races and putting together my training. I’m just happy with the outcome.”

The humble O’Callaghan said she “really wanted to share the podium with these girls”.

“The 50m free and the 400m free, it was really cool to see all three (Australians) on the podium,” O’Callaghan said.

“Meg did amazing, Shayna did amazing . . . it’s just amazing to be a part of. It’s such a privilege to race with these girls.”

In the last event of the night, O’Callaghan barely needed to break a sweat in the anchor leg of the women’s 4x200m freestyle final after a lead of more than six seconds was opened up by her teammates Lani Pallister, Hannah Casey and WA’s Inez Miller.

Australia’s swimming superstar, who is competing at the Games while dealing with stress fractures in her back, revealed she was “tossing and turning” over whether to withdraw from the event.

“My body’s not in the greatest shape, but sometimes, when you’re not at your best, you’ve just got to give it your best,” she said.

“If I’m at 80 per cent, I’m going to give 100 per cent of that.

“I knew the girls had my back. Just watching them absolutely dominate each lap, it was very inspiring, and I didn’t want to let them down.

“It was very nice to see how strong they are and how much they lifted and to see the depth come through.”
