The star was pictured lying on the sand in a black bikini, laughing while clutching a bottle of water, after experiencing extreme seasickness in Christmas Island.
Captioning a carousel of snaps, Poh wrote: “Next to cooking with the island aunties, exploring the protected waters of Christmas Island was the thing I was most excited about.
“Embarrassingly, Will Cook and I proved to have terrible sea legs (sorry to cut the party short Ngāhuia Reneé Trewartha), but for the time we were out, we managed to see the most stunning array of fish.”
The star included some beautiful videos of the crystal clear waters, with her pals agreeing that it was a fantastic trip.
“Let’s do this again Poh!” wrote Ngāhuia Reneé Trewartha, while Will added, “What a special day indeed!!! Even with the milo induced illness…”
Poh also told her followers that her brother was a “massive fish nerd”, so to get the opportunity to see so many varieties of fish was a “huge thrill” for her.
The 48-year-old shared another photo from a magical sea grotto, donning a bikini that showed off her figure.
“Having a dip in The (beguiling) Grotto which was roaring that day,” she wrote.
The cookbook author’s fans adored the shot, with one likening it to ‘Jurassic Park’.
“Oh wow! You are stunning! What lovely surroundings too,” another fan wrote.
“Amazing, so beautiful,” added a third.
Poh stuns in ‘fierce’ photoshoot
This comes after Poh unveiled some striking looks in her South Australian Style shoot.
The I’m A Celeb star opened up with the magazine about how her relationship with her mum affected her cooking.
Poh believes her mum is to thank for her success in the cooking world, revealing it’s thanks to her the star could ‘pipe like a ninja’ at just nine years old.
“When I was tiny, she expected things to be executed flawlessly — anything from measuring a cup of flour (with no spills, thank you) to finishing the tiny curl at the end of a cursive ‘a’," she revealed.
“For all the times I might have resented her for being such a harsh task-master when I was a kid, as an adult, I can only be full of gratitude,” she finished.
