Australia pipped by US at world swimming titles but Dolphins’ golden era endures | Kieran Pender

Mollie O’Callaghan and Kaylee McKeown were not the only Australians to shine in Singapore, whether individually or collectively

Australia’s golden generation in the pool is going nowhere. That much, at least, was clear in Singapore over the past week, as the Dolphins ended the 2025 world championships on eight gold medals, just one shy of perennial rivals the United States. With some swimmers only recently back in the water following a post-Olympics break – Ariarne Titmus participated from the commentary box rather than the pool – and a bout of food poisoning derailing some athletes, it was an impressive outing from the Dolphins.

Two swimmers were at the forefront, responsible in whole or in part for five of Australia’s eight gold medals – Mollie O’Callaghan and Kaylee McKeown. O’Callaghan, still only 21, went level with Australian swimming great Ian Thorpe on 11 world titles, thanks to two relay golds (the women’s 4x100m and 4x200m freestyle), and an individual title in the 200m freestyle, plus two silver medals.

Katie Ledecky once again proved untouchable in her signature event, holding off a star-studded field to win her seventh world title in the 800m freestyle on Saturday in Singapore, a feat no swimmer has ever achieved in a single event.

The 28-year-old American delivered a championship-record 8:05.62 to edge Australia’s Lani Pallister (8:05.98) and Canada’s Summer McIntosh (8:07.29) in one of the most anticipated races of the world swimming championships.

Backstroke queen Kaylee McKeown pulls off another golden double

  • Australia reels in US rival Regan Smith

Kaylee McKeown, the world record-holder, underlined her status as the undisputed queen of backstroke as she added 200m gold to her triumph in the 100m at the world championships in Singapore on Saturday.

Once again it was American Regan Smith attempting to take down McKeown, only to be reeled in on the last lap as the Australian clocked 2min 03.33sec, the third-fastest of all time. It was nearly a second better than Smith (2:04.29), who had taken silver behind McKeown in the 100m and 200m at the Paris Olympics, and was runner-up to her in the 100m in Singapore.

‘King’ Kyle Chalmers out to reassert dominance over princeling upstarts at swimming worlds | Kieran Pender

The Australian has always positioned himself as the underdog but his enduring brilliance – and medal tally – suggests he should be anything but

It is rare to find such a decorated athlete – one with a regal moniker, no less – who still thrives on being the underdog. Australia’s Kyle Chalmers, “King Kyle”, has won just about everything there is to win in international swimming. Yet year after year he returns, somehow still the underdog, somehow ready to spring another upset.

In recent days, at the 2025 World Aquatics Championships in Singapore, it has been more of the same. On Sunday, Chalmers anchored Australia’s relay team to an unexpected gold in the men’s 4×100m freestyle relay.

Summer McIntosh v Katie Ledecky: a generational duel set to define the world championships

The teenage phenom from Canada is chasing five golds in Singapore, but her showdown with the sport’s longtime 800m free queen could signal a passing of the torch

For the first time in more than a decade, Katie Ledecky may not be the most feared swimmer in the pool. That honor now belongs to Summer McIntosh, the Canadian teenager looking to do what only Michael Phelps has done before her: win five individual gold medals at a single world swimming championships.

Their clash in the 800m freestyle on 2 August is set to be the defining moment of the weeklong meet in Singapore.

Hard work for Australian swimmers on road to LA 2028 begins in Singapore | Kieran Pender

Swim events at the World Aquatics Championships get under way this weekend as the Dolphins put the drawing board behind them

Barely an hour after the Australian swim team had completed a successful meet at the Paris Olympics, the Dolphins head coach, Rohan Taylor, was already looking to the future. “We’ll go back to the drawing board,” he said on the pool deck. “Performance by design” is one of his often-repeated mantras. So relentless is the pursuit of gold that the following morning, the Dolphins held a debriefing session to reflect on improvements ahead of the Los Angeles Olympics in 2028.

In the year that followed, Australia’s swim stars have enjoyed time away from the pool. Some retired – the nation’s most successful Olympian of all time, Emma McKeon, brought the curtain down on her glittering career, and had a local pool named in her honour. Some tried their hand at other activities – 50m and 100m freestyle star Shayna Jack featured on I’m A Celebrity … Get Me Out Of Here!, while middle-distance titan Ariarne Titmus is still out of the water, recently on commentary duties at the Australian swimming trials.
