The Jillaroos have beaten the Kiwi Ferns to win the Pacific Championship title, after a series of errors led to the New Zealand side playing catching up for most of the game.

In front of a sold-out crowd at Parramatta’s CommBank Stadium, the Kiwi Ferns were unable to punch through Australia’s defence enough and fell short of the title.

Ashleigh Quinlan’s sin-bin just a minute into her time on the field added to the Ferns’ woes and an ugly hip-drop tackle also sent Ivana Lauitiiti off for 10 minutes, leaving the New Zealand side with only 12 players on the park for 20 minutes.

“They’re almost unstoppable, aren’t they?” said Emma Lawrence on Nine.

“The Jillaroos came in as heavy favourites … They are a team of genuine superstars and it’s very hard to find any type of weakness across that line-up.”

The Australian side came out early with the first try of the match three minutes into the game from Olivia Kernick to take a 6-0 lead.

Julia Robinson solidified the Jillaroos’ charge, able to sneak through the Ferns and score for the Australian side.

“Does anyone do it better in modern-day rugby league? Her hands are like webs. They just stick [to the ball],” Brad Fittler said on Nine.

The Ferns were reduced to 12 after Quinlan was sent to the sin bin after only a minute on the field.

She was handed the order by referee Belinda Sharpe after Quinlan came into the tackle late and flopped on top of Jakiya Whitfeld, earning herself 10 minutes.

After Whitfeld pulled the Ferns close to Australia’s line, she unleashed and darted towards the middle.

Jess Sergis was in perfect position to follow for support, collecting a slick pass to run away down the field.

At half-time, it was 24-0 to the Jillaroos.

The first try in the second half went to Kiwi Shanice Parker, who put the New Zealand side on the scoreboard.

Tamika Upton hit back with a classy solo try to keep the Jillaroos ahead by 26 points.

“They look unstoppable,” Fittler admitted on Nine.

Tysha Ikenasio scored a try for New Zealand but its errors continued as Apii Nicholls missed both conversion attempts.

With 10 minutes to go in the final, Ivana Lauitiiti was sin-binned after an ugly hip-drop tackle sent Olivia Higgins sprawling on the field.

In back play, Annessa Biddle was in a world of pain after being clobbered in the head by Ellie Johnston’s left knee as she went low for a tackle, and again when the rampaging prop’s knee plunged into her face as she lay on the ground.

Johnston then crashed over for a try from close range before Robinson bagged her second four-pointer of the day as the Jillaroos rounded out a 40-8 win.

Robinson was awarded player of the match.
