Aussie Olympic star Ariarne Titmus has produced the fastest-ever split swim in the women's 200m freestyle helping Australia break the world record at the Commonwealth Games in Birmingham.

In a stunning night for Australian swimming, Madi Wilson, Kiah Melverton, Mollie O'Callaghan and Titmus broke the world record in the 4x200m freestyle relay.

The quartet set a world record of 7:38.29 to surpass China's old mark by 1.04 seconds.

Canada finished 12 seconds behind the Aussies in second place.

And 21-year-old Titmus showed why she is truly a special athlete after leaving her mark on the race with the fastest 200m split swim of all-time with a time of 1:52.82.

Titmus has become the first female swimmer to ever record a time under 1.53, having surpassed Italian star Federica Pellegrini's mark of 1:53.45.

Fans were left gobsmacked at the distance Titmus put between herself and Canada in the final leg, thanks also to a strong swim from her teammates.

Aussie swimming icon Ian Thorpe was left stunned at the team's swim in the final.

"Australia's won that by more than 12 seconds," Thorpe said on Channel 7 commentary.

"That is really extraordinary and we spoke about it earlier, the depth that we have in relays and sprints."

Viewers also joined in on the praise for the Australian relay team.

Coach Dean Boxall goes off after Ariarne Titmus record

Titmus' extraordinary performance also sparked her lively coach Dean Boxall into life.

Boxall's eccentric celebration at Titmus' stunning 400m gold victory, over Katie Ledecky, at the Beijing Olympics made headlines around the world.

And the swimming coach was at it again as he willed Titmus to victory in Birmingham.

Cameras showed Boxall rallying the Aussie troops to lend more support during the relay.

After realising Titmus had helped the Aussies break the world record, Boxall celebrated wildly with Titmus' family and team.

Australia enjoyed a blockbuster run in the pool in Birmingham having won three gold in the space of 60 minutes.

One of those was Emma McKeon who claimed victory in the 50m freestyle on Sunday night to clinch her third gold medal of the Games and 11th of her career.

She came to Birmingham with eight gold medals in two previous editions of the Games.

McKeon leaves as the most decorated Commonwealth Games gold medallist of all-time with 11.
