US actress Kaitlyn Dever has divided fans with her attempt at an Australian accent in the new Netflix series Apple Cider Vinegar.

The mini-series tells the story of notorious Australian cancer fraudster Belle Gibson, with Dever taking on the main role.

But her attempt at a convincing Australian accent has sparked controversy, with many taking to social media to debate the merits of Dever's Antipodean cadence.

Writer Bec Shaw got the discussion started over on X, formerly known as Twitter, sharing a trailer for the soon-to-be-released Netflix series.

'Australian accents are hard,' she wrote, indicating she was less than impressed with Dever's attempt.

However, Bec went on to clarify that she was a fan of the actress, who Bec suggested was 'thinking too much' about the accent.

'I don't think this accent is bad btw, but it's not quite right and it feels like she's spending some brain power on it, which you’d have to because it’s so f***ing hard, she added.

'She also may be helped by Belle's affectations. Anyway I'll watch obviously.'

Another X user agreed  with the assessment, arguing that Dever's delivery was 'wrong'.

'It's not bad, but the way she delivered the lines in that trailer make it sound a bit like she was having to think about it too hard, the cadence isn't natural,' they wrote.

Another chimed in with a similar: 'Nothing dramatised can measure up to the freakiness of the actual interview she did with 60 [Minutes] argh,' referring to Gibson's infamous TV appearance.

'Also I feel like our accents are so class-coded & she has this specific private school accent that she herself is faking as a Launceston born, public high school kid.'

Another jumped in claiming that there have only ever been three actors in the history of television and cinema that have successfully pulled off an Australian accent.

'Dev Patel in Lion, Sean Harris in The Stranger and Tom Burke in Furiosa are the only three times I've seen a non Australian pull off a convincing Oz accent,' they claimed.

Others argued that the role should have been given to an Australian actor. 

'There are plenty of Australian actors who would have done a much better job,' wrote one.

Yet another jumped in arguing that Dever's accent was passable - but that it was simply from the wrong region. 

'This is a fine Australian accent,' they wrote. 'It's just for the wrong age group, region and social class.

'Gibson has a really distinct "desperate striver from just outside Brisbane" accent.'

Apple Cider Vinegar is set during the early days of Instagram and follows two young women who set out to cure their allegedly life-threatening illnesses through health and wellness, influencing their global online communities along the way.

The real Belle Gibson, now 33, once claimed she had terminal brain cancer which was cured by simply eating healthy food - but it was later discovered she never had the disease.

Her shameless lie became a cause célèbre in Australia, and the story of 'Healing Belle' will soon be told around the world.

In 2013, Belle Gibson launched the @healing_belle Instagram account where she gained a large following through sharing so-called 'healing' food recipes.

She claimed her lifestyle and healthy eating plan had 'cured' her inoperable brain cancer, which she had supposedly been diagnosed with at the age of 20 and given just months to live.

Belle claimed she had undergone conventional cancer treatments, including chemotherapy and radiotherapy, before abandoning modern medicine to follow a program of clean-eating instead.

Before long the deals began to roll in, with Gibson launching an app full of recipes as well as a book deal, reportedly worth $420,000.

However, in 2014, the Melbourne-based personality claimed that despite her new wellness-focused lifestyle, her cancer had returned, and this time it had spread.

Following an investigation by Fairfax Media, now Nine Newspapers, it was discovered none of the charities Belle had named had received a cent from her.

The influencer's story quickly began to unravel, and in April 2015 she was forced to admit she had lied. 

She also appeared in a trainwreck interview on 60 Minutes, where she was grilled about her many falsehoods by reporter Tara Brown.

Two years after her admission, Belle was fined around $410,000 after being found guilty of misleading and deceptive conduct.
