It was a memorable night on January 26 for I’m a Celebrity Australia 2025 as the 13th celebrity to join the cast made a dramatic entrance — none other than the iconic Australian actress, Sigrid Thornton.

The legendary film and TV star made quite the splash, tied to train tracks as the Jungle Express rushed “out of control” towards her.  Fellow contestant and Bondi Rescue star Harrison Reid was tasked with earning 13 stars in 13 minutes while diverting the train to save Sigrid!

Her stint on I’m a Celebrity 2025 marks Sigrid’s reality TV debut, and we can’t wait to see what this Aussie legend will bring to the South African jungle

Scroll on for all the details on Sigrid’s latest chapter on I’m a Celebrity 2025.

Who is Sigrid?

Sigrid has been a fixture in the Australian film, television, and theatre scene for over four decades. She’s starred in some of Australia’s most beloved films, including The Man From Snowy River, as well as The Lighthorsemen, Snapshot, Scare Campaign, and more, with the 2024 national release of the indie film Slant marking another feather in her cap.

Aussie fans probably know her best from her TV resume, which is seriously impressive. She shone in Nine’s flagship drama Amazing Grace, rebooted the hit SeaChange, and graced the screen as a series regular on Wentworth. Her portrayal of Judy Garland in the miniseries Peter Allen – Not the Boy Next Door earned her the AACTA award for Best Supporting Actress.

Most recently, Sigrid starred in Lifespan of a Fact at the Sydney Theatre Company in 2021 and tackled Andrew Upton’s adaptation of The Seagull in 2023. 

Throughout her illustrious career she’s collected an array of awards, including Logies, People’s Choice, and in 2019, she received the Chauvel Award and CinefestOZ Award for her exceptional contribution to Australian screen arts.

So, what’s Sigrid Thornton doing in the I’m a Celebrity jungle?

On her first Tok Tokkie, Sigrid shared what motivated her to join the I’m a Celebrity cast: to finally be herself. 

“I played doctors, nurses, psychopaths, prisoners, you name it. And now here I’m gonna play me, which is both exciting and terrifying,” she said.

“I’m an actor. You may know me from films like The Man from Snowy River, television series like SeaChange and Wentworth. I’ve been an actor most of my life,” she continued.

“I think people might be surprised to know that I’m actually a very serious dag. That’s gonna be fun to reveal, and I’m also an optimist. I’m a team player, and I don’t mind getting my hands dirty. Let the games begin!”

As Sigrid joined the camp alongside her hero Harrison, the other contestants were quick to express their admiration.

“She is a superstar, one of the most brilliant Australian actors ever, and I cannot believe she’s in the jungle,” said Dave Hughes, who played tour guide to the acting titan.

Sigrid shared with the Tok Tokkie that she felt a strong sense of “warm camaraderie” with her new jungle family.

It’s still early days, so we can’t wait to see how Sigrid fares in the camp. Will she claim the title of Queen of the Jungle? We’re keen to find out!
