The Maroons hooker and reigning Dally M Female Player of the Year will head south along with Kiwi Ferns trio Kimiora Nati, Maitua Feterika and Teuila Fotu-Moala joining a Dragons squad that already includes nine members of the Blues State of Origin-winning side.

They'll form part of what's shaping as a formidable roster at the disposal of returning women's coach Daniel Lacey.

"Brittany is the best hooker in the game," Lacey said.

"She will bring plenty of hype to this team and push the entire squad in the right direction. Her record and achievements speak for themselves.

"There's no doubting she'll add several strings to our bow and change the way we approach games. We are very excited by what she'll bring to the team and I think she can get even better, which is a scary thought for opposition teams."

Playmaker Nati will be part of an exciting spine alongside Breayley and Blues halfback Maddie Studdon, while Feterika Fotu-Moala will bring plenty if muscle up front.

"With Kimiora's signing, we now have two experienced playmakers with fantastic kicking and running games," Lacey said.

"Players like Kimiora are only going to benefit our game management. Her performance in last year's Women's Premiership grand final proved to me what she is capable of producing no matter the circumstances.

"Through her presence, her commitment, her tackle technique and everything in between, Teuila is a player everyone wants to play with and not against.

"She'll bring size and intimidation to our pack, and is coming to the Dragons to become even better than what she already is despite being one of the more recognisable players in the game already."

Feterika boasts the rare distinction of having represented New Zealand, Samo and Queensland.

"Maitua has already expressed to me she wants to win another Women's Premiership grand final," Lacey said.

"I know when Maitua plays and trains at her best, she brings a whole different level of energy and commitment which in turn only helps her team's game.

"She's played a number positions over her career already also which is something I'm keen to further explore."
