The Prince of Wales posted a personal message as the Lionesses roared through to the World Cup on Wednesday.
Prince William took to the social media platform X, formerly known as Twitter, as the full-time whistle was blown.
"What a phenomenal performance from the @Lionesses – on to the final! Commiserations to @TheMatildas, you've played brilliantly and been fantastic co-hosts of this World Cup. W," he wrote.
Sarina Wiegman's squad saw a 3-1 victory against Australia in a thrilling semi-final match at Stadium Australia.
Ella Toone gave the Lionesses the lead in the first half, with The Matildas' Sam Kerr scoring an equaliser in the 63rd minute.
England's Lauren Hemp made it 2-1, before Alessia Russio netted the Lionesses' third goal to seal a place in the final.
The Lionesses will now face Spain in the World Cup final on Sunday 20 August. It comes just over a year after the team's victory against Germany at the UEFA Women's Euro 2022 final.
Meanwhile, William has been president of the Football Association (FA) since 2006, and has been a huge advocate for promoting and supporting women’s football.
The Prince visited the Lionesses at St George's Park in Burton-upon-Trent, Staffordshire in June, to wish the players and staff good luck, ahead of the tournament.
William also surprised head coach Sarina with an honorary CBE, with the royal joking that he did not usually "travel up and down the country to present them" but said: "There's one person that deserves this more than anyone else."

Father-of-three William was also joined by his daughter, Princess Charlotte, as they recorded a special video message for the Lionesses ahead of the Euro 2022 final last year.
The Prince said: "We both want to wish the Lionesses the best of luck for tonight. You've done amazingly well in the competition and we are rooting for you all the way."
Charlotte finished by adding: "Good luck, I hope you win. Bye."
William presented the squad with the trophy at the final, as the England squad defeated Germany 2-1 in a nail-biting final.
However, HELLO! understands that the Prince will not be travelling to Australia to attend the World Cup final.
William and Kate are thought to have been spending time at their Norfolk residence, Anmer Hall, while their children are on their school summer holidays.
The Princess was spotted at a festival last weekend at nearby Houghton Hall.
The couple are also expected to join King Charles and Queen Camilla at Balmoral Castle for their summer break in the coming weeks.
