Chris Hemsworth has just arrived in Sydney after a trip to Fiji.
The Hollywood superstar arrived at the airport in style, having flown home on a private jet.
The Australian actor was joined by his older brother Luke, 43, and Luke’s wife Samantha.
The group had visited the tropical paradise to celebrate the 40th birthday of Chris’ best friend and longtime personal trainer, Luke Zocchi.
The 40-year-old superstar showed off his toned arm muscles in a black tank top paired with black pants.
He was wearing a cap and looked busy as he made a phone call while waiting outside the terminal.
The siblings were also accompanied on the trip by their parents, Leonie and Craig Hemsworth.
Chris paid tribute to Coach Zocchi in a photo posted to Instagram on Monday.

The actor also posted an old picture, showing off his slimmer figure when the two men were still children.
The new photo showed just how much they had grown into men and how much impressive muscles they had developed along the way.
“Happy 40th birthday to one of my best friends @zocobodypro. You are one of a kind brother,” Chris wrote in the caption alongside the image.
Zocchi, who lives near the Hemsworth clan in Byron Bay, helps the superstar and his wife Elsa Pataky work on their physiques for blockbuster roles.
Speaking exclusively to FEMAIL, Luke said that weight lifting is key for those who want to lose weight and build muscle.

Luke’s wife Samantha (pictured) came with them, as did his parents Leonie and Craig Hemsworth.
Luke also shared that Elsa, 48, used the same program Chris followed for his new blockbuster, Thor: Love & Thunder, to get in shape for her role as the very ripped Captain JJ Collins in Interceptor, which left her in “the best shape of her life.”
Both Elsa and Chris used the Power program, designed by Luke, on Chris’s fitness app, Centr.
To build your biceps to resemble those of the God of Thunder, Luke recommends working your upper body during the first four to six weeks of a new training regimen.
“Keep the weights at a manageable level and the reps as low as possible,” he says.
‘Then I would try to challenge myself a little more each week – I would increase the intensity of the weights I use and increase the reps from 6-8 to 8-12.
‘I would focus on two sessions of ‘push’ movements and two sessions of ‘bring’ movements to make sure you’re working all the different muscles you’re working.
