Moree Boomerangs will take on Narwan in the decider

The Boomerangs finished the regular season in third and had to topple Tingha and Inverell to qualify for Sunday's big dance.

It was 12-all at half-time in the preliminary final but then Inverell managed to get out to a 30-12 lead.

The Boomerangs pinned them back and a Will Fernando field goal sealed the 31-30 victory.

But the hard work as just begun.

The Boomerangs and Narwan have a long history with Koori knockouts, players turning out for both clubs as well as some formidable match ups over the years.

Although they will be travelling, to Armidale's Bellevue Oval, club president Peter Duncan is confident his team can take out the title in what he labelled as "the game of the decade."

"Both of the clubs' goal for the end of the season is to be there at the back end and one of us to take it out," he said.

"We have finally achieved it after all these years.

"It doesn't matter who they have, and us, no matter what, we know they are going to turn up and play footy."

And Duncan has every right to be confident.

The Boomerangs are the defending champions and their ladder position could have been higher if not for losing points earlier in the year from naming unregistered players.

Nonetheless, the team is in the big dance and Duncan believes their recent effort against the Hawks has put them in good stead.

"I think after last weekend's game, that is the best preparation we could have had for a grand final," he said.

"Backs against the wall down and out, then just to know we can put on those points.

"It was a big effort from our guys to bounce back.

"The boys just lifted, picking up, started being a bit more patient with the ball and just made them pay."

And they are hoping to go up another gear for the big dance.

"You dream of these moments," Duncan said.

"Got the best oval, the best setup and it is going to be a banger. We are going to blow them off the park."
