 A new Concert Music department was formed in 1985 to coordinate the corporation's six symphony orchestras, which in turn received a greater level of autonomy in order to better respond to local needs.Open-air free concerts and tours, educational activities, and joint ventures with other music groups were undertaken at the time to expand the orchestras' audience reach.ABC Radio was restructured significantly in 1985 – ABC Radio 1 became the ABC Metropolitan Network, while ABC Radio 2 became known as Radio National (callsigns, however, were not standardised until 1990).
