He is one of Australia’s most successful Hollywood stars, starring in a hit Marvel series.

And on Friday, the Byron-based actor celebrated his 40th birthday.

One of his famous brothers posted a lavish tribute to his sibling to mark the occasion, sharing a cute series of commemorative photos of them together as kids.

In one picture, the star has a blonde bowl-cut and poses in a bright blue and red jumper.

In another instance, the two wear identical outfits – a blue shirt and shorts – and pose in front of a trailer.

The star in question is none other than Thor star Chris Hemsworth.

His brother Luke Hemsworth captioned his post: “Happy 40th birthday to my brother my best friend.”

“You are an inspiration to everyone who knows you.” You are the sunlight in dark places and a shield for those who need it. I love you buddy.’

Luke and Chris also share a brother, Liam, 33, who is best known for his work on The Hunger Games and is set to star in The Witcher.

Liam has also shared some recent snaps of himself and his brother Chris, including one of Chris zipping around shirtless in a car and one of him cuddling up to a dog.

The Hemsworth brothers are all incredibly close and own various properties in Byron Bay, where they are all based.

Chris, Liam and Luke’s total investment in the popular region is estimated at over $100 million and spans 124 hectares – and their portfolio is only growing.

Thor star Chris and his wife Elsa Pataky are the leading landowners, starting with their mega mansion.

After buying his family’s Byron Bay home for $7 million in 2014, Chris transformed the sprawling estate into one that ranges in value from $30 million to $60 million.
