Nowra-Bomaderry ageless wonder Mick Blattner insists the Jets' turbulent start to their premiership defence hasn't tempted anyone to reach for the ejection lever.

The titleholders lost to Milton-Ulladulla by two points in the opening round and went down 42-28 in Saturday's round two road clash with Gerringong.

But kicking off the season with a run of losses is nothing new to Nowra-Bomaderry. Last year they were so poor in the early rounds that the wooden spoon didn't seem out of the question.

But the Jets completely turned their fortunes around to finish third before advancing to the grand final and upstaging favourites Warilla with a 30-20 triumph.

Blattner, a first grade veteran of 26 seasons, has been through the highs and lows and is confident his team won't stay winless for long.

"We're not panicking," the 41-year-old journeyman said.

"Last year was a fairytale season to win the grand final, because we started with a draw and lost our next four.

"Obviously we don't want to do that again, but the problem at the moment is that we're probably missing seven or eight first-graders through injury and suspension.

"Port Kembla for us this weekend is a must-win. We're still very positive and we'll just put our heads down and keep going. We've got a run of games against Port Kembla, Kiama, Albion Park, Shellharbour and Warilla, so we want to win four or five of those."

Nowra-Bomaderry captured the imagination of Group Seven followers with last year's premiership victory.

Few gave them a chance of even reaching the grand final after they lost to Shellharbour in the opening week of the finals.

But they bounced back to beat Gerringong in the minor semi-final, exacted revenge on Shellharbour in the final and stunned minor premiers Warilla in the grand final.

Blattner said not everyone was swept up in the sentiment of the Jets' success.

"There's a bit of talk around that we're big-heads, but we're not big-heads," he said.

"There's no way [captain-coach] Ben Wellington, [halfback] Geoff Johnson or myself would let our team have big heads. I've heard a few comments like 'let's bring those big-heads back down to earth'. There's none of that in our team. We know it's a tough competition and we're just focused on getting that first win.

"We're all aware of having that tag as premiers, especially after watching the way Milton celebrated when they beat us in the first round.

"It really showed a few guys that teams are always going to lift to play the premiers."
