In a match that is expected to be pretty fiery, Bega co-coach Billy Hudson said the team will be trying to avoid the niggles and aggravation the Snowy River Bears will provide.

Hudson himself has been sidelined with a back injury, while he also faced a Group 16 judiciary Wednesday night from an incident with the Bears.

He will take a leadership role for the Roosters on the sidelines, while his fellow coach and Group 16 best and fairest winner Ricky Stapleton leads the troops on the field.

"We need to play our own game," Hudson said. "Don't get involved in the niggle as they seem to try and get under the skin. I am confident we can handle ourselves - winning the grand final is our task, not fighting."

He said in previous encounters with the Bears, early points tend to lift the Roosters, while it dips the head of the Bears.

"We have played pretty good starts with early points off the back of that so we just need to get in the grind early on and go forward - everything will come off the back of that."

With himself ruled out, the task at hand will fall to the other forwards.

"To win I have no doubt our forward pack is where we need to aim up, and our halves will have to play smart footy."

The Bears will front up with a strong forward pack of their own, while the visitors also boast a bit of size around the fringes.

The Bears are coming to Bega at full strength after rebuilding the club this season.

The Bears won't be the first club to make a return in the competition and finish with a grand final spot after the Candelo-Bemboka Panthers did the same on their return.

Meanwhile, the Roosters have had the premiership locked up since 2016 and will not be aiming to gift it to the returning mountain club.

"We have had some good talk at the club this week, we've spoken about the way they will try to get under our skin and niggle us," Hudson said.

"But we are there to do a job and that is what we are going to do - I'm confident in the group we have."

"We will just play our own game and rip in for the 70 minutes to hopefully do Bega proud."

Hudson commended his co-coach Stapleton on his recent award as a tremendous defensive player and a great asset out of dummy half to guide play on the field.

"Ricky has been outstanding this year and I am sure he will get the boys rolling forward."

The Roosters will carry a few injuries into the weekend, but Hudson said with the depth of juniors coming through the Bega outfit would look to a bit of support from the youthful ranks.

"We're relying on a few young blokes, but I have full confidence in the 20 blokes in our team to do the job," he said.

The clubs have met three times this year with Bega getting the result in two of those.

The Bears clinched a 32-10 win in round seven, before the Roosters flipped that result 30-16 in round 16.

Their most recent clash was the major semi-final, where the Roosters picked up a 26-18 result.

Group 16 officials reckon a majority of the Jindabyne region will make the trek to Bega on Sunday to cheer on the Bears, while Bega will count on a vocal home crowd.
