The Aussie Diamonds put a week of turmoil and chaos behind them, to turn out a big win over the Silver Ferns on the Gold Coast in the final match of the Constellation Cup.

The Diamonds gave themselves a chance with a big win on Wednesday night, and came out firing with plenty of early physicality in the opening stages of the finale.

It wasn't all one-way traffic, as the Silver Ferns took the first and second quarters, and the Diamonds found themselves five goals down at half time.

Maddy Gordon in wing attack and Ameliaranne Ekenasio in goal attack were running riot for the Silver Ferns early, as the New Zealand side found the circle edge with ease.

The game was physical early, with the umpires handing out a number of cautions to players. After the game, Diamonds captain Liz Watson explained the feeling out on court.

"It was physical," Watson said.

"I think the physicality definitely stepped up, the umpires wanted to control that and not let it get out of hand. It was more the delayed contact or the late call that probably got us the cautions."

The Diamonds came out of the half time break with a new vein of form, and dominated the third term by 11 goals, turning the match on his head.

After the game, Diamonds' coach Stacey Marinkovich explained how she saw the improvement after half time.

"We just needed to find our connections," Marinkovich said.

"I thought we presented really strongly for the first ball, but weren't setting each other up for the next line of play, and when you don't do that - we couldn't get the ball speed.

"Full credit to New Zealand, their box, their zone was stretching us further so we needed to get that movement happening earlier and it was really hard to get ball early.

"I thought we had initial stage touches as soon as we started, and then it dried up. Once we got the connection, and we talked about that at half time, then you saw us build pressure and get ball speed."

Marinkovich's half time pep talk was accompanied by changes to the lineup, with Amy Parmenter introduced and Jamie-Lee Price shifted to centre.

As the Diamonds' new lineup gelled, it was Sophie Garbin and Steph Wood who benefitted the most, with ball finding its way freely down to the goal circle.

Garbin finished with 36 goals (from 39 attempts) and Wood finished with 21 goals (from 27 attempts), as they terrorised the New Zealand defensive end. The Diamonds shooters found consistent space and freedom inside the circle, and an easy path to goal, taking the pressure off the rest of the team.

After the game, Marinkovich was emotional as the trophy was presented to the coach and captain. She explained after the game how much the success means to her.

"There's no doubt I showed a bit more emotion than I did at Comm Games.

I live and breathe what this team goes through, and I think our loudest voice is what we do on the court.

"We take huge pride in how we present when we play the game of netball."

For Marinkovich, there is a satisfaction to winning a competition like Constellation Cup, where the Diamonds face the same opposition repeatedly, rather than a different opposition each time like the Commonwealth Games.

"Playing a Constellation Cup, playing the same opposition consecutively does really challenge you," she said.

"It's who can adapt and shift, and you can tell that they've gone and done their homework on us and you've got to come back and challenge, and have to respond."

For Marinkovich, she reflected on the growth of the Diamonds' squad over the past while since they last played at home, and particularly across the three major international tours this year.

"There's huge growth. Every experience has been slightly different, and you come into a series and you don't know exactly what you're going to get in terms of your opposition and where they are about to be based.

"I have loved the fact that we had to rely on us as a group to drive standards, drive a game plan completely, buy in to the direction we were going, and I think the players have really brought to life what this program is all about, and I think the connection we have is strong.

"You can see when somebody speaks and delivers feedback, you listen and there's a reaction on court, and a reaction in the changeroom, and it's a great environment when we get the time together."

For the Diamonds, they will now turn their attention to the England Roses, with a three match series starting Wednesday.
