Membership of the Association is open to local government in rural and regional Australia where the timber industry is recognised as being significant to the local and national economy as well as community. Forest industries and other forestry based interest groups are not represented by the NTCA.
Each member council may nominate two representatives to attend meetings, one of whom must be an elected councillor.
Administration of the NTCA is vested in the Executive Committee. This committee comprises eight nominated representatives from member councils across the state and territories, forming a representative view across Australia.
