The former Home And Away actress, who also stars in Baz Luhrmann’s £60 million new version of The Great Gatsby, said she got into trouble after being submerged for two-and-a-half minutes.

‘They had a guy who was off camera, but he was a long way away with a can of oxygen,’ she said. ‘By the time I realised I couldn’t get up and beckoned for him, I realised that I had run out of air.

‘Luckily, I managed to get free and stay level-headed and got out before it went even more horribly wrong.’
