History

ABN-2 Sydney opened on 5 November 1956 with full-time colour broadcasting introduced in March 1975.

For more than 40 years, Gore Hill was best known as the location of the ABC's Sydney television studios, which were fully opened in 1958 and which operated until 2002, when the site was closed and sold off. Later, the ABC moved its television operations to its broadcasting centre in Ultimo.

The station has also carried a number of programs originally produced at Channel 31 stations in other states (programs such as Aurora Community Channel & National Indigenous Television.

ABN commenced digital television transmission in January 2001, broadcasting on VHF Channel 12 while maintaining analogue transmission on VHF Channel 2.

The analogue signal for ABN was shut off at 9.00am AEDST, Tuesday, 3 December 2013.
