Australians Ali Brigginshaw, Brittany Breayley, Heather Ballinger and Caitlin Moran have all penned contracts along with the first international signing for an Australian club Kiwi Teuila Fotu-Moala.

"Coach Paul Dyer and our team have gone through a thorough process to craft our squad and we are really happy with the players we have in our sights, both in their ability on the football field and their attitude off the field in terms of buying into the Broncos culture," Broncos NRLW CEO Tain Drinkwater said. 

Jillaroos five-eighth Brigginshaw, who is Ipswich born, was player of the match in last year's World Cup Final and is also a lifelong Broncos fan.

Hooker Breayley, is also another Queensland from Mckay who was named Queensland Women's Representative Player of the Year in 2017 and a Jillaroo since 2014.

Prop Ballinger is the third Queenslander and originally from Cairns.

The 35-year-old has been part of the Jillaroo's successful 2013 and 2017 World Cup squads.

Unfortunately, for Jillaroos halfback Moran who had relocated to Queensland to be a part of the Broncos ruptured her ACL two weeks ago ruling her out of the 2018 season.

However, the Broncos made a commitment to honour her playing contract originally intended and will support her through her rehabilitation.

Moran joined the Broncos in May as an Education Support Trainee working out in schools providing support and mentoring as part of the Beyond the Broncos Girls Academy programs.

Fotu-Moala has become the first New Zealand representative to sign with a club. 

The 27-year-old is a  backrower and was named Player of the Tournament at last year's World Cup.

The Broncos become the second of the four clubs to announce their signings for the season with the Sydney Roosters and New Zealand Warriors still yet to make signings.
