Prime Minister Scott Morrison reveals why he won't let his daughters, 13 and 11, watch hit Netflix series Squid Game

South Korean survival drama Squid Game has become the most popular show on Netflix since its release last month.

But Australian Prime Minister Scott Morrison has revealed he won't be letting his daughters, Lily, 13, and Abbey, 11, watch the series.

Mr Morrison told Melbourne breakfast radio show Fifi, Fev and Nick on Thursday the program was 'too confronting' for his two girls.

'I watched it in my last quarantine. I must admit it was a bit confronting,' he said.

'I won't be letting my daughters watch it, I can assure you of that. It was novel, it certainly broke the mundanity of quarantine.'

Squid Game has soared to popularity globally since its release last month, with Netflix co-CEO Ted Sarandos saying it has a 'very good chance' of becoming the streamer's most popular show yet.

The South Korean series is a survival thriller set in modern-day Seoul, where a group of 456 people are invited to play a series of children's games with the chance to win a huge amount of money - but if you lose in the game, you lose your life.

Earlier this month, director and creator Hwang Dong-hyuk revealed his work had been rejected for 10 years because of its 'bizarre' concept.

'After about 12 years, the world has changed into a place where such peculiar, violent survival stories are actually welcomed,' he told The Korea Times.

'People commented on how the series is relevant to real life. Sadly, the world has changed in that direction,' he added.

'The series' games that participants go crazy over align with people's desires to hit the jackpot with things like cryptocurrency, real estate and stocks. So many people have been able to empathise with the story,' Hwang continued.

He also admitted he knew Squid Game would be a 'a masterpiece or a quirky flop', because the 'idea behind this work was very experimental'.
