Noradjuha-Quantong has claimed back-to-back A Grade premierships in the Horsham District Netball Association.
The Bombers burst out of the blocks early, establishing a seven-goal lead over Edenhope-Apsley by half-time at Horsham City Oval on Saturday.
Noradjuha-Quantong coach Shannon Couch said the strong start proved crucial.
"We had a bit of a lull in the third quarter and let them back into the game," she said.
Couch said her side managed to control the tempo of the game well when it was tested.
"We worked the ball a fair bit and played it slow," she said.
The Bombers held on to win 41-34.

Couch was one of five Bombers who also played in last year's premiership, alongside Chloe Anson, Rebecca McIntyre, Hayley McDonald and Georgia Francis.
It was her first premiership as coach.
"It's very exciting," she said. "I knew we could do it I trusted the girls and their ability."
Goal attack Alex Bensen was named best on court in the victory.
"It is Alex's first season at the club and she did a good job," she said.
"I thought Rebecca McIntyre was fantastic in defence too, getting lots of rebounds."
Edenhope-Apsley coach Leonie Lang said she was proud of her team.
"I thought our girls played well and I was very happy with them," she said. "We were just out-rebounded.
"Their height at either end was the difference."
The Saints threw everything at the Bombers, including switching Emma Ryan from defence to attack in the second half, but couldn't come away with the win.
It was the Saints' fourth consecutive A Grade grand final loss.
"The girls did well just to get there again," Lang said.
