The amazing effort he put in for his charity, which Nick co-founded following the tragic passing of his sister Maddie in 2015, made the win all the more special for the AFL champion.
His win may not come as a complete surprise to most, as from the moment he walked through those kitchen doors, Nick was a clear frontrunner.
He even had the bookies convinced, with both Sportsbet and TAB placing him in the number one spot at 1.10.
"Winning was never the reason for participating, BUT it does feel good to finally lift some silverware (cue the memes🤪). Wow what a bonus @maddiesvision !!!!" he wrote on Instagram late last night.
"Thank you to the ultra cool judges @fooderati @andyallencooks @zonfrillo , @bensonmarty and the entire @masterchefau crew for helping us keep our heads. You guys made it the most amazing experience. Thank you 🙏."
Having described himself as a "psycho competitor", Nick constantly proved to the judges and viewers at home that he has the skills to handle the kitchen.
He even managed to impress judge Andy Allen, to the point where he hinted that Nick could be this year's celeb champ from the very beginning.
"This is the stuff that wins you the competition," Andy said, after Nick served a dessert style egg and soldiers dish.

While he managed to take home the win in the end, Nick first had to tough it out against nine other talented cooks in the pressure cooker environment.
This season we saw incredible dishes plated up by actress Rebecca Gibney, Olympian Ian Thorpe, fashion designer Collette Dinnigan, Gordon Ramsay's daughter Matilda Ramsay, and radio host Chrissie Swan.
Also battling it out in the kitchen was actor Matt Le Nevez, multi-instrumentalist performing artist Dami Im, football legend Archie Thompson, and comedian Dilruk Jayasinha, who each put in an amazing effort.
