Naomi Osaka earned her second Grand Slam title with a thrilling three-set win over Petra Kvitova, and gave a hilarious acceptance speech at the post-match presentation on Rod Laver Arena.
After taking the first set, Osaka had three match points in the second, but couldn't convert as Kvitova mounted an amazing comeback.
Osaka needed a few moments to compose herself ahead of the third set, but held her nerve to claim a 7-6(2) 5-7 6-4 victory.
The result means Osaka will become the number one player in the world when the WTA rankings are updated on Monday.

Notoriously shy - even awkward - in front of a microphone, Osaka had the crowd laughing during her winner's speech.
"Hello - public speaking isn't really my strong side, so I just hope I can get through this," she joked.
"Huge congrats to Petra - I've always wanted to play you.
"You've been through so much and I didn't want this to be our first match-up.
"You're amazing, and I'm really honoured to have played you in the final of a grand slam."
Giving her speech while holding the Daphne Akhurst Memorial Cup, Osaka mentioned the intense Melbourne weather.
"I want to thank you guys for coming and watching...it's really hot all the time," she said before placing the trophy on a table.
"Even though it's really hot, you guys come and show support, so I really want to show my gratitude to you.
"I read notes about this, but I still forgot the rest of what I was supposed to say.
"Thank you, everyone, and I'm really honoured to have played in this final."

The speech comes 10 months after Osaka's debut WTA singles title at Indian Wells last year.
On her way to the title, Osaka defeated the likes of Maria Sakkari, Karolina Pliskova, Simona Halep and Daria Kasatkina.
After taking the final in two sets, Osaka gave the first of what is sure to be many victory speeches.
And like in Melbourne this year, it was pretty funny - even if she described it as "the worst acceptance speech"
