After several years as coach of the national youth team, and having been rumoured for the head national coach position since the late 1980s, Plummer was the obvious favourite when Jill McIntosh resigned in July 2003, and subsequently took the reins of the national team in late August. In her nearly three years as coach for the Australian team, she has retained her prior reputation as a hard coach willing to axe even star players if not performing, and remains widely respected, even with a downturn in the team's fortunes during 2005.
