Chris Hemsworth and his wife Elsa Pataky flew from Sydney back to Byron Bay via a private jet on Saturday.

The Hollywood power couple are both filming new movies in the state's capital and often travel back home on weekends.

Chris, 37, dressed casually for the flight in a white T-shirt and black track pants.

The actor teamed his ensemble with a pair of grey sneakers, green cap, silver watch and black sunglasses.

Meanwhile, Elsa looked casual chic as she stepped on the plane in a black T-shirt and grey trousers.

Chris has been working on new marvel film Thor: Love and Thunder in Sydney and is also rumoured to be producing Elsa's forthcoming film, Interceptor.

According to News.com.au, the Thor star will serve as an executive producer on the Netflix film.

Elsa will lead the film as a soldier who must save the world when 16 nuclear missiles are launched in the United States.

Australian actor Luke Bracey will co-star, but Elsa's husband is not expected to act in the movie, instead settling for a behind-the-scenes role.

Chris and Elsa's trip to Byron Bay comes one day after they enjoyed a night at the footy, cheering on Russell Crowe's beloved Rabbitohs.

At the game on Friday, where the Sydney Rabbitohs battled the Sydney Roosters, the couple joined the likes of Isla Fisher, Natalie Portman and Jeff Goldblum in a private box.

Also in the box were the likes of Thor: Love and Thunder director Taika Waititi, actress Tessa Thompson and Idris Elba's wife, Sabrina Dhowre Elba.

Natalie was also accompanied by her husband Benjamin Millepied, 43, with the pair showing their support by wearing caps supporting Chris' favourite team.

The arrival of so many A-list Hollywood stars in Australia in recent months has seen New South Wales, and the celebrity haven of beach side town Bryon Bay, dubbed Hollywood 2.0.
