St George Illawarra have finished the 2018 Telstra Premiership regular season at seventh place and will face the Brisbane Broncos on Sunday, September 9 at Suncorp Stadium (4:00pm).
The Broncos' 32-point win over the Manly-Warringah Sea Eagles on Sunday afternoon saw Brisbane jump the Dragons into sixth on points' differential to earn a home semi-final.
The Dragons inaugural NRL Holden Women's Premiership clash has also been confirmed to take place at Suncorp Stadium against their Broncos counterparts in what will be a thrilling double header.
The women's Dragons' team will kick-off at 1:45pm in their maiden and historic clash against the Brisbane women.
The ISP Dragons meanwhile booked their place in the preliminary final on Sunday afternoon following their last gasp 28-26 win over the Newtown Jets.
