The 32-year-old took to Instagram to share a photo of them cuddled up in bed together while eating breakfast.
The caption read: "Flashback to the morning after our unforgettable wedding.
"At our happiest when we wake [up] to food. Weird waking up to a random stranger that now is my husband."
It comes after fans of the show accused Ning of "pressuring" Mark into sex during their Blue Mountains date.
However the mother-of-three told 9Honey that "it was the most romantic date".
"It was absolutely beautiful and so romantic," she said.
"We were away from civilisation and closer to nature with no phone reception - meaning no interruptions. But there was a lot of pressure from everyone to do the deed."
