The Brisbane Broncos have added another three players to their squad for the 2018 NRL Women's Premiership Competition, while also announcing its first sponsors for the historic season.

National Storage and Arrow Energy will both partner with the Broncos' NRLW team, with more commercial supporters to be announced in coming weeks.

On the field, Blackwater backrower Mariah Storch joins the Broncos' squad after making her debut in the 2018 Holden Women's State of Origin Queensland team. Mariah, who currently works as an apprentice diesel mechanic for Thiess, played for Queensland Country at the 2018 National Championships.

Experienced winger Karley Te Kawa is a New Zealand international who has found the tryline regularly during her career.

Young Queenslander Taylor Mapusua brings depth and experience across both rugby league and rugby union codes, having won a gold medal with the Australian Rugby Sevens team at the Youth Commonwealth Games in 2017.

The latest signings mean the Broncos now have 20 of their 22-player squad locked down, with the final spots to be determined next week.

Brisbane Broncos NRLW CEO Tain Drinkwater said: "We've assembled a great collection of talent in our playing squad, both in terms of their ability on the field, and their values and commitment to the team off the field.

"We are also really excited to welcome National Storage and Arrow Energy as our commercial partners – they are both long-term supporters of our Club and it's fantastic that they have put their support behind our NRLW team."
