"Flashback Friday to deal or no deal #fail," he captioned one post, which was uploaded in 2015 but appears to be from an episode in 2013.
On another he added: "After double value cases and a second chance ... It was very upsetting 😞😞😞 oh well."
Mikey’s previous girlfriend, fitness influencer Katie Williams also had a brush with TV fame, appearing on the first season of Australian Ninja Warrior in 2017.
On Channel Nine's official website, Mikey is described as a “private school boy from Sydney's leafy north shore”.
“Although Mikey has always enjoyed the spoils of an affluent upbringing, he is genuine and open-minded, with a solid work ethic,” his bio reads.
“He recently stepped up to help run the family business: a nursing home that his grandfather founded.”
