This is Rugby League (As opposed to Union), so they roll the ball under foot (other team goes a few meters away at this time). This teams possession (and the game) would end as soon as the ball is kicked out of the playing area. So literally she needed to just kick the ball like 2 meters and they would have won. Possessions in Rugby Union are a lot more ethereal, basically whoever has the ball is in possession, and they keep possession by being given small advantages.
