Nathan Buckley was seen feeling unwell.

Thattil yells, “Guys help, can we please get a medic! He’s just fainted!”.

Two crew members then rush by his side before paging a team of medics, saying, “Tell them it’s urgent”.

It is not known what caused Buckley to collapse, or whether or not he will be deemed well enough to continue on the reality series.

He was seen fainting as his campmates tried to help him.

Crew members quickly rushed to his aid.

It comes after Buckley opened up on Tuesday night’s episode over his struggle with media intrusion amid his separation from his wife of 18 years, Tania Buckley.

“I’m going through a separation, so I’ve been out of home for 18 months, a bit over 18 months, nearly two years,” he said.

“The paps are following my ex-wife and sometimes with my boys. And they’re also looking for photos for me with my current partner.”

News of Buckley’s marriage breakdown – and his subsequent relationship with cosmetic nurse and model Alex Pike – came as a huge shock to the AFL world, the pair establishing themselves as one of footy’s golden couples during his playing days with Collingwood.
