The Bombers confirmed on Tuesday evening that Parish has inked a new contract that will keep him at the club until the end of the 2023 season.
Parish has enjoyed a breakout season in the red sash, rising into Brownlow contention as one of the league's best contested ball winners.
The retention is a huge boost for the Bombers, who recently re-signed gun onballer Zach Merrett to a long-term deal.
Parish's new deal will take him to free agency, but will still be a sigh of relief for coach Ben Rutten for the time-being.
“We have a really clear plan under ‘Truck’ (senior coach Ben Rutten) and Dyson’s (captain Dyson Heppell) leadership and we’re all really determined and hungry to build on what we’ve started this year, but we know we have a long way to go.
“It’s been a really enjoyable place to be this season. I think that is really evident to our members and supporters and we have a lot of growth in us as a developing team. I’m excited to continue to build my own game and to see what’s in store as we continue to develop as a playing group over the coming years.”
