Rosie Kelly recorded seven try assists, five forced drop outs, 19 goals and a try during the 2026 NRLW season.
The 26-year-old former Black Ferns representative will join the Canterbury-Bankstown Bulldogs on a three-year deal.
She brings 27 NRLW appearances across three seasons with the North Queensland Cowboys and Parramatta Eels.
Kelly can play five-eighth or in the centres, and took over the Cowboys' kicking duties from Round 5.
She finished the season in the no.7 jersey, playing every minute of every match.
Bulldogs NRLW head coach Mark O'Meley said Kelly would be a valuable addition to the squad.
"Rosie is a great addition to the squad. She's a quality player who brings plenty of experience, competitiveness and toughness to the group," he said.
"I really like the way she goes about her footy. She's consistent, works hard for her teammates and has a great attitude towards her game. She's the type of player who puts the team first and brings plenty of value both on and off the field."
O'Meley added: "We're looking forward to welcoming Rosie to the Bulldogs and seeing what she can bring to the program over the next few years."
Kelly will start training with the club when pre-season begins in 2027.
