National Transmission Agency

Its main function was to administer the transmissions of the Australian government's network of broadcasting stations.

The NTA was established in July 1992 by the Australian government to supervise the operation of the National Transmission Network (NTN).

The NTA's funding agreement with the Department of Finance required it to meet savings and performance targets.

A significant source of extra funding to the NTA was "site-sharing" of transmission facilities with commercial broadcasters, telecommunications companies and emergency service communication networks.

Macquarie Bank completed its acquisition of NTA in 2002 and re-branded it as Broadcast Australia.
