GWS have confirmed first-year forward Toby McMullin will make his debut on Sunday against Port Adelaide.

Taken with the 34th selection in last year's National Draft, McMullin will be the Giants' fifth debutant of 2023 when he steps on the Adelaide Oval in Round 22.

The 19-year-old has impressed at VFL level this year, averaging 12.8 touches and 2.9 tackles per game as a pressure forward.

Coming into the Giants' side to replace the suspended Xavier O'Halloran and Toby Bedford, McMullin said he's excited to get his chance at AFL level.

“It's a real sense of excitement and a bit of relief as well,” he said in a club announcement.

“With ‘Snooze' [Toby Bedford] and ‘Binga' [Brent Daniels] out I knew there were spots opening up but there's no guarantees in football so I still just had to go about a normal week and let it unfold.

“But I'm over the moon and that excited to get out there.

“I'll try and bring my defensive pressure as much as I can. Then on offense, use my power and speed and hopefully hit a few targets is the aim.

“There's obviously a fair build up but I'm so excited to get out there.”

The selection nod adds to a busy week for McMullin, who signed a two-year extension on Wednesday to remain in the orange and charcoal until the end of the 2026 season.

McMullin follows Aaron Cadman, Josh Fahey, Cameron Fleeton and Harry Rowston to debut for the Giants this year.

GWS will face Port Adelaide at 4:40pm (AEST) on Sunday at Adelaide Oval.
