Power and his team came away from the grand final rematch knowing they could have piled on even more points in a match where they outclassed the Barbarians in every facet of the game.

Once Jacob Watkin found the opening try of the match 10 minutes into the game it was one way traffic as the defending premiers came close to mirroring the 30-0 result from last year's decider.

Barbarians weren't without their chances through the game but the Mungoes defence were there to deny them on every occasion, while the hosts did enough with their better field position to run away with the game.

Completions were not worth bragging about for either side as the signs of opening round rust were prevalent in both camps.

Power knows that's something the team can improve greatly on as they look to learn quickly from their errors.

"It wasn't too bad. I'm happy but there's a lot for us to work on. We didn't complete many sets and we only kicked the ball three times. We gave away a lot of penalties as well, probably 12 or 13 of them," he said.

"I am happy with how the squad has come together and how quickly they've gelled."

Braydon Wicks, Brayden Blow, Zach Hunt, Adam Booth and Blake Schaefer all got on the try scorers list for the Mungoes in the comfortable win.

Mungoes were reduced to 12 men on two separate occasions as Joe Coady spent a stint on the sideline in each half.

The first spell was earned for backchat and the second for getting caught up in an on-field schuffle, for which Orange were also reduced to 12 players.

But Mungoes handled the situation well and the squad were more than capable of rising to the challenge.

Power said some signs of rustiness were to be expected due to the late competition start and the tricky build up to the coronavirus-affected season.

"We just took our chances when they came and got a bit lucky at times. We had the better possession," he said.

"Our vice-captain Joe Coady had two sit downs on the bench so we played down for bits of the game but we had blokes who were capable of filling in.

"We didn't put Joe on after the second sin bin. We had 22 blokes on the day and it wasn't a big issue having him sit through the rest of it. It was 22-4 at that point.

"I think the game still went better than a lot of us thought it was going to go."

The Mungals went one step better than the CSU boys as they completely shut out the Barbarians in a 38-0 victory earlier in the day.

The five-time defending champion club had far too much pace for their opponents as their title defence got off to a near-perfect start.
