Goodwin has been in scintillating form this season in the Raiders Premier League side, and has been knocking on the door of first grade with a string of solid performances.
Although yet to make his first grade debut Goodwin said he is excited about remaining in Canberra, and believes he has a solid future with the Raiders.
"I'm glad my future has been decided and I am even happier it's with the Raiders," Goodwin said. "I really want to play first grade and I think it will happen here."
Raiders Premier League Coach Andrew McFadden said he believes Goodwin has the attributes to become a regular first grade player, and will continue to get better as his career progresses.
"Bronx has things that other players haven't got," McFadden said. "He has great on field vision and anticipation, and I think he has what it takes to become a regular top grade starter."
McFadden said Goodwin's on field application and determination are second to none, and his form this season has warranted another Raiders contract.
"He's a real competitor and one of our most consistent performers week in week out," he said. "This has been his best season by far and I think he will get better every year he plays the game."
Goodwin also gives Canberra another goal kicking option in the top two grades, with Clinton Schifcofske's departure at the end of the season.
