Australians have won big at this year’s Golden Globes, with Sarah Snook and Elizabeth Debicki taking home acting awards and Margot Robbie winning for Barbie’s box office success.

Snook won the best actress in a TV series – drama for her performance as the ambitious Shiv Roy in Succession, which also won best TV drama.

“I was kind of hoping I didn’t have to get up,” she joked, suggesting that fellow winner Kieran Culkin should have accepted the award on her behalf. Snook won in her category against Helen Mirren, Bella Ramsey, Keri Russell, Imelda Staunton and Emma Stone.

Debicki won best supporting actress in a TV series for her performance as Diana, Princess of Wales, in The Crown, seeing off competition from Abby Elliott for The Bear, Christina Ricci for Yellowjackets, J Smith-Cameron for Succession, Meryl Streep for Only Murders in the Building, and Hannah Waddingham for Ted Lasso. She thanked her “beautiful pretend children” in the Crown as well as her family back in Australia. “Goodness, maybe that’s it,” she said breathlessly after a silence, provoking laughter from the crowd.

Also on Sunday night, actor Stone thanked the Australian screenwriter Tony McNamara for his work on the film Poor Things, for which she won best actress in a film – musical or comedy.

“I love getting to say this dialogue and I love getting to work with you on my Australian accent, she said, before demonstrating it with: “You’re the best Tony.”

For her performance in Barbie, Robbie missed out on best actress in a film to Stone, but accepted the inaugural award for cinematic and box office achievement with Barbie director Greta Gerwig. The new award was introduced to reward box office success in a move seen by many as the Globes’ attempt to introduce an audience’s choice category.

“We would like to dedicate this to every single person on the planet who dressed up and went to the greatest place on earth: the movie theatres,” said Robbie, who also served as executive producer on the film.

She thanked “the brave individuals at Warners and Mattel for taking an extraordinary risk and literally inventing numbers to justify greenlighting this and standing by it every step of the way.”

“Thank you to Noah Baumbach for showing his inner Barbie girl,” Gerwig said, thanking her husband and fellow screenwriter.

“Thank you to Ryan Gosling for going full beach,” Robbie added.
