Surprisingly, it turns out Koby actually had a reason for the campside interrogation – and no, it wasn’t just because he was nosy.
Taking to his Instagram Story, Koby offered his explanation for the choice of questions.
“I want young kids to know how much sports stars earn. In my height I earned $250k a year to do what I love and that’s surfing. I would of surfed for free,” he wrote.
“Kids want to be TikTok/Youtube and Instagram stars these days. Not on my watch son. That’s why I asked Mark Philippoussis on live TV. There is a method in my madness always.”
Tagging in Mark, he addressed the tennis ace directly but stopped short of apologising, writing: “If I offended you, well that’s life.”
Controversial Koby has become one of the central figures in Channel Seven’s hit reality show as he is put through his paces in gruelling physical challenges by Chief Instructor Ant Middleton and Directing Staff Ollie Ollerton, Jason “Foxy” Fox and Mark “Billy” Billingham.
Alongside Koby are stars such as Jett Kenny, Jana Pittman, Sam Burgess, Isabelle Cornish and more.
