The father of new Olympic champion and swimming star Ariarne Titmus has described her win in the 400 metre freestyle as extraordinary.

Steve Titmus joked he lost his voice after the race which saw Ariarne power home to claim gold in Tokyo.

He described her win, beating five time Olympic champion Kate Ledecky as “surreal”.

“It was the perfect swim, it was just extraordinary,” he told Scott Emerson.

With 50 metres to go, he knew his 20-year-old daughter had done it.

“With 15 to go, and she started to stretch her legs, that was the moment I knew, I could actually say my daughter is an Olympic champion.”

Mr Titmus also spoke to Scott about moving from Tasmania to Queensland to be trained to Dean Boxall.

“I have never ever come across anyone who is more passionate, who lives and breathes what he does as a sports coach.

“I think I can say this without any argument at all: he is the best swimming coach in the world. Maybe the best sporting coach currently we’ve got in the world.”

When Brisbane was officially named as the host city for the 2032 Olympics, Mr Titmus said his daughter was thrilled.

“When Brisbane got awarded the 2032 Games, she found that so cool, so fantastic.

“Up until that point, she mentioned that she didn’t think she’d be swimming in 2032, when that happened, and we spoke to her on Facetime from Tokyo, Scott I think there might have been a glint in the corner of her eye thinking wouldn’t it be fantastic to swim at home, I think we will have to wait and see on that one.”
