Callum Hann has come a long way from the baby-faced 20-year-old we first met on the second series of Master Chef Australia.
11-years later, he's created a successful career around food, with his own cooking school and multiple restaurants to his name.
But while he's proud of his professional accomplishments, being a dad to his 18-month-old daughter Elle is what fills his heart the most.
"It's pretty incredible," Callum, 31, tells TV WEEK, as he comes back to the Master Chef kitchen as a mentor.
"I like the challenge of trying to turn her into a good person."
While Callum and his wife, Crystal, are keen on expanding their little family, for now he admits that Elle is keeping them busy enough.
"It's something that we would like to do at some stage but at the moment we're still figuring out how to do the first child. Crystal has her own business as well so it's a delicate balance of trying to get the timing right," the talented chef says.
For Callum, who believes that he's done more episodes than any Master Chef alumni, coming back to the kitchen is always served with a dash of nostalgia.
"It's definitely got a special place in my heart," Callum shares.
This time, he's excited to be back alongside his close friends and past Master Chef contestants Poh Ling Yeow and Reynold Poernomo.
"People will be familiar with us as contestants but I think it's a great reminder that people who have been on the show have gone out and created their own food business which is the whole reason to come on in the first place; you want a career in food.
"I think Master Chef genuinely helps that."
