Tuggeranong won a second straight grand final with a comprehensive 68-55 win over Arawang at the Lyneham Netball Centre on Sunday.

Goal shooter Jo Pivac led the way for the defending champions and hopes the title marks the start of a dynasty.

"Next year let's strive for three in a row," Pivac said.

"It's exhilarating. I can't tell you how excited I am right now."

Two titles on the trot is a scenario Tuggeranong coach Nicole Bowles could not foresee leading into the game – she admitted she "wasn't confident".

"It's absolutely amazing, I can't believe it," Bowles said.

"It's been a tough season for us and I really didn't know coming into the game ... but the girls did absolutely fantastic."

Arawang were first on the board in their seventh-straight grand final and took a slender one-goal lead into the break to the delight of the 'Arawang Army'.

But from then on it was all one-way traffic as Pivac steered her side to a six-goal lead at the main break ahead of a stunning third-quarter onslaught.

Four minutes into the third term Tuggeranong's lead was out to 11 and before long it was a 15-goal advantage, with unforced errors undoing the fancied Arawang outfit.

Trailing 53-40 heading into the final quarter it was clear Arawang needed something special, and for a few fleeting minutes it looked as though the miracle would come to fruition.

Arawang goal shooter Jacoba Clough found the net and immediately looked at the clock knowing her side was in a race against time.

But Tuggeranong wrested the momentum in the centre court and found their tall targets in Pivac and goal attack Amber Brophy.

Brophy found herself with a big role to play in the final term after Tuggeranong goal attack Sophie Immonen was helped off the court with an ankle injury.

"We know Arawang's a really tough side and they always are going to fight back hard," Bowles said.

"We never felt comfortable; it was about coming back hard every quarter.

"Amber was absolutely fantastic out there. She's a young kid and, to be put in that situation, she's an absolute champion."

Meanwhile, Canberra Netball Association went back-to-back in division two with a comfortable 55-39 victory over Tuggeranong, while undefeated Arawang won their fifth straight division three title in a 46-45 thriller over South Canberra.
