According to Emerald City, Isla and her comedian husband Sacha Baron Cohen made the move Down Under because they didn't want to raise their three children in Trump's America.
The couple have been spotted holidaying in Byron Bay - arguably the country's celebrity capital - and rung in the new year with their A-list pals Chris Hemsworth and Elsa Pataky at their space-pirate themed party.
Isla even shared a snap of her New Year's Eve costume in which she points her plastic gun at the camera.
"C’mon 2021 it’s time to zap Covid #thankf**kforthevaccine #happynewyear," she cheekily captioned the photo.
Isla and Chris Hemsworth both kicked off their acting careers starring on Home and Away but she and Elsa share a similar love of Australia's natural beauty.
"I have to say; the most beautiful country is obviously Australia and my favourite place is down south on the Margaret River in South Australia," Isla revealed to WHO as part of the 2019 Most Beautiful People issue.
"It’s like my spiritual home, I love it so much and I feel so beautiful and confident when I’m there. It’s got such a link to my childhood and who I am."
She also told Marie Claire: "I have this secret fantasy of slowing down, moving to Byron Bay, getting off the grid and sitting on the sand with a Vegemite sandwich."
Similarly, Elsa gushed about her home Down Under to the Sydney Morning Herald and stated that she will never live in LA again.
"It is my dream, I always wanted to be in a place like [Byron Bay]," she told the publication. "Growing up I was very happy in nature, with animals, and I dreamed of living in a place where my kids can run around with no shoes on, surrounded by all kinds of animals - dangerous and not dangerous."
Ahead of filming for his new film Thor: Love and Thunder, Chris, Elsa and their family visited Lord Howe Island east of Port Macquarie with some of their close friends.
"Great to get away for a few days to @visitlordhoweisland before starting on #thorloveandthunder this week!" Chris captioned his photos.
Elsa shared a similar selection of vacation pics, writing on Instagram: "So great to come back to this amazing paradise! @visitlordhoweisland #holydaysandfriends @australia."
Wonder if Isla and Sacha will be joining them for their next holiday...
