Both the reserve grade side and the under 18s will contest the grand finals with their opponents to be decided this weekend.

Impressively, the under 18s team have gone through the competition so far undefeated but coach Wayne Grant said the achievement means nothing if they fail to win the final game of the year.

"It does mean bugger all if we can't win the next game," he said.

"But they're not getting ahead of themselves, they're confident not cocky and they treat the other teams with respect."

It's that attitude that Grant said is the reason for the teams success.

But he admitted the quality of the players also played a big part.

"They are a good side," he said.

"Their attitude is spot on, they train hard and they're committed.

"But our bench is really strong too.

"Whenever we make any replacements we don't lose anything which has created a few headaches in its own right when it comes down to selecting what the squad will be."

Attitude was high on the agenda for reserve grade captain coach Bob Davison as well.

"Our self belief and gelling as a team has got us through especially the last few weeks," he said.

"We've gotten behind a bit but we've managed to get out of trouble and grind out a win."

The reserve grade side will play the winner between home town rivals the Port City Breakers and the Macleay Valley Mustangs.

That game will take place this weekend.
