Aussie Olympics superstar is pictured having her very first swimming lesson with her dad - can you tell who it is?

She's currently one of the biggest stars in Australian sport thanks to her incredible record in the pool - and she's been pictured enjoying her very first swimming lesson with her father helping keep her afloat. 

The pool queen in question is just 23 years old, is coached by the swimming guru who helped turn Leisel Jones and Stephanie Rice into household names, and she hails from Tasmania. 

Still not sure? She's Ariarne Titmus, the Australian swimming champion who won three gold medals at the Tokyo Olympics and who has already claimed gold at the Paris Games.

She is pictured with her father Steve, testing the water for the first time, long before anyone knew she would become one of the nation's greatest swimmers.

Born and raised in Launceston, Titmus fell in love with swimming early on. 

'I still remember her first swimming lesson,' her dad Steve recalled. 

'Ariarne kept putting her head under the water. The instructor got really annoyed and kept saying, "Ariarne, stop putting your head under the water, we'll get to that shortly".

'I remember it as if it were yesterday because it was one of those light-bulb moments.

'You knew that Arnie loved being in the water, so her early swimming lessons were quite a joy.'

With her heart set on swimming, Titmus and her family decided to move from Tasmania to Queensland to pursue better swimming opportunities. 

'If one goes, we all go,' her mum Robyn said.

'We were united on that.'

After settling into Brisbane, Titmus began training with South African-born Dean Boxall at the St Peters Western Swim Club in Indooroopilly, the same swim club that trained Australian gold medallists Jones and Rice. 

It wasn't long before she started making waves on the world stage.

In 2016, at the Junior Pan Pacific Swimming Championships hosted in Hawaii, Titmus won a silver medal in the 4×200 metre freestyle relay and a bronze medal in the 400 metre freestyle. 

A couple of years later, at the 2018 Commonwealth Games, she would win three gold medals — in the 400 metre freestyle, 800 metre freestyle, and the 4x200-metre freestyle relay — as well as a silver medal in the 200 metre freestyle.

This was just the beginning of Titmus' journey on the swimming world stage that would lead to her gold medal victories at the 2021 Summer Olympics in Tokyo. 

Titmus and Mollie O'Callaghan both cruised into Monday night's 200m freestyle final as the top-two qualifiers. 

Titmus touched in one minute 54.64 seconds, six-hundredths of a second quicker than O'Callaghan in second.

Just six weeks ago Titmus broke O'Callaghan's world record in the event and the Paris final looms as a match-race between the swimmers who are both coached by Dean Boxall. 

Titmus is seeking to become the first swimmer to successfully defend 200m and 400m freestyle titles at an Olympic Games.

On Saturday night, she banked the first leg of the double by winning the 400m freestyle while O'Callaghan also collected gold as part of Australia's triumphant 4x100m freestyle relay team.

Titmus was in disbelief at becoming just the second Australian woman swimmer to keep an Olympic crown after the great Dawn Fraser. 

Fraser, who watched from the raucous grandstands at the Paris La Defense Arena, won 100m freestyle gold at the 1956, 1960, and 1964 Games.

'I can't really believe that's me,' Titmus said of joining Fraser. 

'It's fun racing the best in the world. It gets the best out of me. I hope with all the hype we have lived up to expectations.'

'I just look at myself and I'm so normal ... I'm just the same old goofy Tassie girl living out her dream.'
