Nowra-Bomaderry captain-coach Ben Wellington rejects suggestions that Sunday's season-ending duel with Warilla is little more than a dead rubber.

The Jets will finish third regardless of this weekend's results.

Few at the club would've thought such a feat was possible after Nowra-Bomaderry won just one of their opening six games.

They turned their season around and are keen to soar into the play-offs on a high note.

"There's no real pressure on where we're going to finish, but it's important that we perform and keep playing with that good harmony we've got going," Wellington said.

"Like any team, we need a good run going into the semis, so we're not holding anything back in this game."

An entertaining 30-30 draw ensued when the Jets hosted the Gorillas in June.

Nowra-Bomaderry might not have a lot to play for on Sunday, but competition leaders Warilla must win to be assured of the minor premiership.

Wellington expects a torrid battle in the forwards.

"They're such a big team across the park," he said.

"We've worked on our line speed a lot, and if we control the ruck and get in their face we'll be in with a shot.

"We've got good attack. We can pretty much score from anywhere, in the wet or the dry, but we have to make sure we get our defence right."

Wellington said his team had become a close unit.

"At the start of the year we were still finding our way because we had a lot of new faces," he said.

"We're just starting to gel now at the right time. We're playing for each other, and that's the difference.

"When it comes down to it, it's good to know you've got someone alongside you that's going to give their all for you. We know we can depend on each other.

"Finishing third is really positive for our club and our community, and we feel we can go all the way."

Jamberoo will be playing for pride in their season-ending duel with second-placed Shellharbour at Kevin Walsh Oval.

The Superoos will finish equal fifth with Kiama if they tame the Sharks, but their for-and-against differential is 118 points worse than the Knights.

Kiama have a bye and will square off with title holders Gerringong in next week's elimination semi-final.

Gerringong end their season at home against Port Kembla on Saturday, while Berry-Shoalhaven Heads play Albion Park-Oak Flats at Berry Showground.
