Sunrise co-hosts Mel and Kochie will go head to head this Saturday when the GIANTS take on Port Adelaide at AAMI Stadium.

David Koch took over as chairman of his beloved Port Adelaide at the end of last year while Melissa Doyle is the GIANTS' number one ticket holder.

The pair posed for photographers at Etihad Stadium while they were in Melbourne last week for the Royal Children's Hospital Appeal for Channel 7.

Both are passionate advocates for the game and their clubs and the rivalry will continue when the GIANTS play the Power at Skoda Stadium on June 16.

The GIANTS defeated Port at Skoda Stadium last year to bring up their first win in Sydney in Kevin Sheedy's 1000th VFL/AFL game as a player and coach.
