"I've done my best, cracked some salt in my eyeball," Nick said of his attempts to get it out. "Anyway, he's vacated north and then now he's heading west," the SAS Australia alum added as casually as if he was discussing the weather.
"So he's about there at the moment," Nick said, pointing to where his right eyebrow meets the top of his nose. "It's bloody high, you probably won't be able to see, we'll get the flashlight in."
In gruesome scenes, he then showed the leech coming out the eye, along with some watery blood.
"That was quite an episode," the Honey Badger said after the ordeal. "He finally got him out and he's just having a breather down there at the moment," he added, panning the camera down to his t-shirt where the leech was resting comfortably.
"He got right up in there. I could barely see him. I reckon he was gnawing my brain," Nick concluded.

"What the actual F! Man you need a doctor! How with you get that thing out!" a third wrote.
Despite failing to find love on The Bachelor, Nick has since met "the one" Alex George, with the pair welcoming their first child in October this year.
