The Avengers star was announced as Australia's global ambassador last year, and takes his new role very seriously.
"[My kids] love it!" he told ET of 4-year-old daughter India Rose and 3-year-old twins Sasha and Tristan's reactions to moving back to Australia from Los Angeles. "Where we were in California, and being a part of the big city like that, [it was] very different to where we live in Australia. To be able to walk straight down to the beach and see nobody [is] something that they quickly acknowledge and appreciate."
"My wife loves it [too]," he added.
"When I get home it's straight down the beach and, you know, it's a very different lifestyle I live when I'm at work traveling and that's why we moved back there," Hemsworth explained. "It's in the surf, on the beach with the kids, in the rivers, swimming and so on."
