The Silver Ferns face Australia tonight in game four of the Constellation Cup. 

The series currently sits at 2-1 to Australia, but a win from the Ferns tonight could force an extra game to decide the series. 

Silver Ferns Head Coach Yvette McCausland-Durie told Mike Hosking that, 'it's gonna be hard work, but really confident, based on the way they played the other night, they've got the potential there.'
