Last week, Jason's bulging biceps were on display as he was pictured strolling around Byron Bay's Bluesfest.

The Honolulu native looked in positive spirits as he posed for photos with fans.

Seen laughing and joking with festival-goers, Jason's outfit had shades of Paul Hogan in Crocodile Dundee.

Jason has made a big impression since arriving Down Under to film Aquaman, which is slated for a 2018 release.

Production staff working on the film, which also boasts Nicole Kidman among its cast, praised the actor for his professionalism.

'He's made such a good impression on everyone. Everyone can't praise him enough - especially the action guys. He already has so much respect,' a crew member told News Corp.

After landing the lead role in the comic book adaption, the Conan The Barbarian star professed his excitement at taking on the project.

He said: 'I read the Aquaman script and let me just put it this way, I've never seen a movie that's anything like this. It's going to be a world that you've never seen before, which is really cool.

'We went to space, we traveled all over different worlds, but we never went underwater.

'So it's just a really cool spin on what's below and it uses a lot of great movies that I already love - whether that be Raiders of the Lost Ark to Star Wars to Lord of the Rings to Romancing the Stone.'
