An astonishing rise from the basement to the penthouse is almost complete for Group Seven joint venture Nowra-Bombaderry.

The two clubs were on their knees only a few years ago before deciding to join forces and attack the competition in unison.

Two years later the Jets are a very real chance of winning their maiden premiership.

Warilla's season defined

Just 80 minutes of football and rival club Warilla stand in the way of a remarkable fairytale ending.

Earlier this year the Jets sat bottom of the ladder.

Captain-coach Ben Wellington says the playing group always knew improvement was on the way.

"We've finally got

the right boys in the right spots," Wellington said.

"It's starting to gel, we started gelling halfway through the year.

"Once we started believing in ourselves, there were a few turning points during our season, the boys ran away with it and started closing out tight wins.

"We've got a lot of young guys and this will be their first time [grand final].

The majority of Nowra-Bombaderry's playing list has never experienced a senior grand final.

In fact, it's been 18 years since either of the merged clubs won a title, when the Nowra Warriors took the crown in 1996.

Wellington doesn't want to get ahead of himself, however, as he plots the downfall of competition heavyweight Warilla.

The Gorillas hold the wood on the Jets this season with a win and a draw from their two meetings.

"We've got to muscle up in the middle, get a good kick-chase and turn them around, because they're a lot bigger than us."

Wellington has ruled himself fit to play the grand final after having to withdraw injured last week.
