In 2005, the Roos competed in both the BARFL Premiership and the BARFL Regional competitions, though they failed to make the grand final in either league. In the BARFL Premiership despite committed performances, the guys could not match the greater experience of the London sides and finished 5th, though they did record a memorable victory against a dominant Wandsworth Demons team, the first side outside of the top 3 ever to do so. The club did repeat their victory in the Sheep Stations Cup, this time held in Copenhagen, Denmark, defeating the Farum Young Guns.
