Chris Hemsworth and Elsa Pataky are raising a family of thrill-seekers.

On Wednesday, the Hollywood power couple spent some quality time with their three kids in Byron Bay, and supervised them surfing down a hill during a rain storm.

Elsa, 47, shared a jaw-dropping video to Instagram capturing twins Tristan and Sasha, nine, and sister India, 11, fearlessly braving the elements to slide down a large hill.

The Hemsworth kids were all smiles as they effortlessly maintained grip and steered their way down a hill at a local park, much to Elsa’s amazement.

At one point, one twin lay down on the grass while holding up a plank while his brother surfed over it, propelling himself into the air.

‘Best rainy days in Byron,’ a stunned Elsa captioned the post.

Chris, 40, and Elsa are truly global citizens and the couple proved as much when they recently took their brood halfway across the world on separate holidays.

Marvel star Chris took the couple’s daughter India to Iceland, while Elsa took her twin boys on an adventure-filled trip to Tokyo, Japan.

The family live in a $30million mansion in Broken Head, near Byron Bay, after relocating from Los Angeles to Australia nine years ago.

In June, Chris praised his wife Elsa as he revealed that he wouldn’t of been able to do ‘any of the things I’ve done’ without her ‘sacrifice and support’.

The Aussie actor has carved out an impressive film career since first finding fame on Home and Away, with Chris now being one of the world’s biggest action stars thanks to his role as Thor in the Marvel franchise.

In an interview with British GQ, in which he was the first GQ Heroes cover star, Chris told how his wife’s comfort and encouragement has allowed him to be who he is.
