Chris Hemsworth spends the evening surfing with his kids in Byron Bay

Chris Hemsworth is raising little mini-mes.

The Thor star was seen taking his children for an afternoon surf at a Byron Bay beach on Wednesday.

The actor's daughter, India, nine, and twin boys Sasha and Tristan, both eight, were seen running down the beach with surfboards tucked under their arms.

Daddy day care! Chris Hemsworth was seen taking his children for an afternoon surf at a Byron Bay beach on Wednesday.

The four, all dressed in black wetsuits, started their adventure running headlong into the sea.

Later, they swapped their surfboards out for kickboards for some more in-the-water fun.

At one point, Chris appeared to help a young surfer out of a rip before directing her to a safer part of the beach as she lugged her large surfboard.

A while after, India was seen clinging to her father's back as they waded through the shallows, looking for the next swell.

Towards the end of the afternoon, the hunky actor swept his daughter up into his arms and carried her out of the sea after a wave crashed into the two of them.

Chris shares her three children with his wife Elsa Pataky whom he married in 2010.

The family resides in a $30million mansion in Broken Head, near the celebrity enclave of Byron Bay.

Last month, Chris said he is working on more and more films in Australia.

'My focus ever since I had any sway was to shoot here in Australia due to, on a personal level, being at home with my family, but also because of the awareness that I had about what was possible here when it comes to the talent,' he told The Daily Telegraph.

Chris made his latest film, the Netflix science fiction drama Spiderhead, in Queensland.

His production company, Wild State Productions, brought Thor 3 and 4, Extraction 1 and 2, Spiderhead and Interceptor to film in Australia, the paper reported.

'Life is sweet. It is great and I couldn't be happier,' Chris added.

'If you had have said or asked me 10 years ago where I would like to be, this is it.'
