The star centre has played for the Roosters in the first two NRLW seasons, but will link with the Dragons for the Nines.

That's as far as her current commitment goes, but coach Daniel Lacey hopes it will result in the Newcastle product shifting south for the season proper where she would form a near unstoppable centre pairing with reigning Dally M Player of the Year Jess Sergis.

"Isabelle was on the top of our list to come to the club for the first NRLW season, and I never gave up hope of her becoming a Dragon one day," Lacey said.

"It speaks volumes for what we're doing as a club for her to want to jump ship and get an insight into how we operate. She's only committed to the Nines for now but hopefully we can sit down at some stage and look at her future with the Dragons."

The squad features 13 players who featured in the club's grand final defeat to the Broncos including Internationals Kezie Apps, Shaylee Bent, Keeley Davis, Tiana Penitani, Jessica Sergis, Shakiah Tungai and Botille Vette-Welsh.

"I think having so many girls return for the Nines is good in many ways, for the fact that we get the chance to work together again and build on what we did last year," Lacey said.

"It shows loyalty to the Dragons and will only help consistency-wise."

The tournament will also see the return of the Dragons inaugural NRLW skipper Sam Bremner after an 18-month break following the birth of her first child.

"It's great to have Sammy back on board," Lacey said.

"I get the feeling she has unfinished business with rugby league. She's been really determined to get back out there since the first NRLW season - she only managed to play the one game due to a toe injury.

"That has certainly spurred her on. She's chomping at the bit to be back and certainly someone to watch in Perth."

Winding product Kaarla Cowan has also been added to the squad that features fellow Illawarra juniors Keeley Davis, Rikeya Horne, Maddi Weatherall and Shakiah Tungai.

Cowan has represented NSW City and the Prime Minister's XIII team in Papua New Guinea, with Lacey happy to bring a local product home.

"Kaarla has been on the Dragons radar for a number of years as she's from our local system being a Windang girl," Lacey said.

"She was close to being in our NRLW squad in 2019 after she expanded her horizons in the Sydney competition. Kaarla's versatility has played into this opportunity. She's one of the only individuals who can play in the middle but also at hooker.

"Nines rugby league is perfectly suited for Kaarla and will prove a boost in her progression in the game."
