On the final day of rounds matches at the Pacific Netball Series at Nissan Arena, the First Nations Black Swans flexed their muscles against Samoa to produce a huge second half for their biggest win of the campaign.

After breaking a quarter time deadlock for a three point lead at the main break, Lily Cubby and Oliva Clark combined for 35 goals to Samoa's 11 to end the afternoon 59-32 winners over World Netball's no.17-ranked outfit.

Samoa entered the contest off a 19-point win over Singapore on Thursday.

Clark carried on with her form earlier in the week, while Cubby produced her best performance for the series making life difficult for opposition defenders with accuracy from long range.

"I think we were just giving the ball with confidence, all playing with confidence, backing each other up," Cubby told National Indigenous Times.

I think the main thing is, we have some changes, but we just worked each other onto the courts, making each other so comfortable. That's what our number one priority is…and it clearly paid off.

"I've always actually said to people, I actually prefer the long run shot than under the post. They stress me out a bit more.

"But that's also the confidence from everyone else on court backing me, allowing me to do them."

Charlotte Ryan gave the Blacks Swans a solid start with six in the first quarter before a nine goal addition shooting at 100 per cent leading into half time.

Aaleya Turner and Scarlet Jauncey worked over Samoa's shooters, restricting them to just four in the final period.

Tia Molo provided a game-high 32 feeds, with Kiera Heffernan and Courtney Jones having 24 and 23 respectively in midcourt.

Down back, Jauncey, Turner and Tegan Holland were effective and collected two intercepts each with wing defence Brook Lacey busy assisting in positive ball movement as a tall option heading towards goal.

"Our connection down court, (it was) fast paced…when getting a turnover, just boom boom boom down and shoot," Brook said post-match.

The win makes it four from five successful outings in the invitational side's first crack at international netball.

Their only blemish came at the hands of defending champions Tonga, and within days of coming together for the first time in Brisbane.

Both Lacey and Cubby joked they would love another chance and taking down the team to beat coming into the series.

Speaking to National Indigenous Times mid-way through the week, Black Swans head coach Ali Tucker-Munro said was already impressed by what she's seen across the squad, both on-court and the bigger picture.

"What's been really pleasing is just how the girls have come together as empowered black women, and how they have really just centred themselves and the team culture from the get go," she said.

Tucker-Munro later added "what's been really really impressive to me as a coach is that they've known their job, they know their role, and they execute it beautifully".

The Black Swans end their campaign with a final match outside of the third place and grand final on Saturday.
