Digital Forty Four was a Sydney-only trial datacasting service that was licensed by the Australian Broadcasting Authority (now the Australian Communications and Media Authority) beginning on 17 March 2004 for an initial two-year run until 31 December 2006.

[4] At midnight on 30 April 2010, all services from Digital Forty Four ceased broadcasting.

[5] The services provided at various times during its six years of operation have included a television guide for free-to-air television, a community service channel providing information on road, weather and surf conditions, with live broadcasts every fifteen minutes, the Australian Christian Channel, Expo shopping channel, NITV, Teachers TV information channel and live broadcasts of the meetings of the Australian Parliament, with audio-video coverage of the House of Representatives and Senate.

As it was a long term trial, many channels that started on the service did not continue until the cessation of broadcasts.

Most of the other channels on Digital Forty Four are available unencrypted on satellite or via online streaming.
