Barrass was one of three West Australians drafted by the Eagles on Thursday and was overjoyed to stay in Perth and join the club he passionately follows.
"It's an unbelievable feeling," Barrass said.
"It's pretty hard to put into words. I'm struggling to know how to feel. It's a bit overwhelming.
"But it's great to stay in my home state. I've been an Eagles boy since I can remember so it's a really great opportunity and I'm really keen to get stuck into it."
The tall, left-footed defender was taken with pick No.43 following an outstanding performance in the WAFL colts Grand Final where he starred in Claremont's six-point triumph.
Barrass believes that was the game that helped secure his fate.
"I think it was pretty good to have a nice game like that in front of the recruiting team," Barrass said.
He joins WA teammates Dom Sheed (pick No.11) and Dylan Main (pick No.49) on the Eagles list, along with South Australian midfielder Malcolm Karpany (pick No.31).
Unlike Barrass, Main was not an Eagles supporter growing up but was recruited by West Coast on one condition.
"They said as long as it wasn't Freo," Main said.
"I actually went for Richmond because of Dad, but it's the Eagles now."
Main is a close friend of Cameron McCarthy who was recruited by Greater Western Sydney with pick No. 14.
The pair grew up together at the South Coogee junior football club.
"Started from Auskick, so I've played with him for 12 years there and this year at South Fremantle," Main said.
"Now I might be playing against him soon, hopefully."
Twelve West Australian players were drafted on Thursday night. WA talent manager Raff Guadagnino expected eight players to go in the top 40 and was proved correct.
"I'm excited because they’ve exceeded expectations and I feel they've really brought honour to the WAFC and the WAFL clubs, in regards to making sure that we're producing the best players for the AFL system," Guadagnino said.
