Appearing on Monday nights Tucker Trial challenge, Tomic joined comedian Fiona O'Loughlin to complete an aerial obstacle course that required him to wear a pair of goggles that made everything appear upside down.
Fiona was calling out directions for Tomic to follow, but it was all too much for the star!
'I am really sick. I am about to vomit, I am out, I am so sick,' he said while still hanging from the ledge.
It wasn't long then until Tomic was saying those fateful words - 'I'm a celebrity, get me out of here!'
The crew stopped the challenge and hosts Chris Brown and Julia Morris, as well as medics, rushed to Tomic's side.
Bernard later headed back to the communal camp site and told his fellow co-stars what had happened. The star's all asked him to stay another day, to which Tomic responded he would sleep on it.
