At the Tokyo Olympics, Ariarne Titmus has taken the swimming world by storm - the thunder from down under who is lightning in the pool.
At her first ever Olympic Games, the 20-year-old has won two Gold medals for Australia.
Her victorious campaign began with her 400m race, where she was swimming next to the defending-champion and world-record holder Katie Ledecky from the USA - the world's greatest female swimmer.
In true Australian underdog style, though, Titmus triumphed against the champion by two-thirds of a second, sending the country into a moment of euphoria.
No one was more jubilant than her couch, Dean Boxall, who screamed and thrusted in a colourful - and now viral - celebration.
Then on Wednesday, Titmus solidified her new crown as she again beat Ledecky in the 200m freestyle final.
Now, she will go for a third Gold. At 1:30pm Australian time, Titmus will compete in the women's 4x200m freestyle race. The team - completed with Emma McKeon, Leah Neale and Madison Wilson - are the favourites heading into Thursday's final.
Here's what else we know about Australia's new queen of the pool.
