Isla also received the Screen Legend Award and thanked CinefestOZ in a separate post where she spoke warmly of her home state.
In one of the photos, the Wedding Crashers star can be seen sharing a candid conversation with her comedian and actor husband, Sacha Baron Cohen.
"Thank you @cinefestoz it’s such an honour to be given the Screen Legend Award, I’m so proud to be recognised in Western Australia. This is where I was raised, this is where I feel at home," she captioned it.
Though she was born in Oman, Isla grew up in Perth before moving to Sydney to star in iconic soap, Home and Away.
She, Sacha and their three children relocated to Australia in a bid to reportedly escape Trump's America.
“I feel like I can be myself in Australia,” Isla told Marie Claire in June.
“I love the people. I love the colours and the sights and the taste and the smells. And there’s something about being home which is just … it feels very magical. I miss it so much when I’m away and I have a very Australian sensibility. Whenever I meet another Aussie, I always think, ‘Oh my gosh, we’re twins!’”

The celebrity mum-of-three, who doesn't share photos of her kids on social media, confessed in 2018 that “juggling a family in LA isn’t easy”.
“There’s not really a culture of bringing your kids to dinner parties or to restaurants past 6pm. I tend to entertain at home because I want to be with my family – it’s easier to put your kids to bed and have a wine with friends,” she told Marie Claire.
