They’re the Hollywood couple who recently appeared to make a permanent move to Australia, amid the worldwide coronavirus pandemic.

And on Monday, Sacha Baron Cohen and his wife Isla Fisher were spotted enjoying a stroll through Byron Bay, just days after it’s believed they attended Liam Hemsworth’s now viral New Year’s bash at his $6.5million mansion.

The Borat star, 49, and his 44-year-old wife cut casual figures as they headed out in the pretty coastal town.

While the pair haven’t confirmed their attendance, it’s believed they travelled to Byron Bay from Sydney to attend the Hemsworth’s star-studded party, which took place on New Year’s Day.

The event was a space pirate-themed party, with guests including Chris’ wife Elsa Pataky, Liam’s model girlfriend Gabriella Brooks and The Voice host Renee Bargh.

On Sunday, Isla posted a picture wearing an ensemble that most definitely fit the bill, as she sported a futuristic glittery top, a tiny skirt and some bizarre metal legwarmers.

Instead of a gun, she posed with a forehead thermometer in her hand, writing in the caption: ‘C’mon 2021, it’s time to zap Covid!’

She added the hashtags #ThankF**kForTheVaccine and #HappyNewYear.

For the party, Elsa was pictured sporting a pink wig and an elaborate pirate costume, which showed off her trim pins and svelte figure.

Chris looked fabulous in a shiny multi-coloured shirt, which he unbuttoned down to his pecs to give just a flash of his ripped torso.

While Liam wasn’t pictured at the party, his girlfriend Gabriella looked like a million dollars in a glitzy gold ensemble in a photo shared on social media.

Renee Bargh looked absolutely incredible for the themed event.

She wore a sequinned black bra, silver hot pants, a cape and goggles.

She teamed her sassy look with a pair of snakeskin boots, and carried a fake silver space gun in her hand as she posed for photos with her jaw-dropping pals.

Meanwhile, Isla and Sacha are believed to be living Down Under permanently, after taking the major step of enrolling their three children at a school in Sydney.

Until recently, the notoriously private family were living in Los Angeles.
