Analog television signals have been switched off in Sydney and surrounding areas, with digital-only reception taking over.
The permanent switch took place at 9am (AEDT) on Tuesday.
The switchover is Australia's largest to date, with more than 1.7 million households involved, bringing the national tally to more than 8.7 million nationwide.
The federal government's Digital Switchover Taskforce says there are only two regions left to make the change.
On December 10, Melbourne and remote and central eastern Australia, including areas of the Northern Territory outside of the Darwin switchover region, will complete Australia's switch to digital-only TV.
People who have not converted have the options of switching to a digital TV or attaching a digital set-top box or digital recorder to their analog TV.
About three weeks ago the federal Department of Communications estimated that six per cent (more than 104,000) of 1,738,200 Sydney households had yet to make the switch.
People needing information on the change can call the Digital Ready Information Line on 1800 20 10 13.
The Household Assistance Scheme and Satellite Subsidy Scheme will also remain open across the Sydney switchover region until January 3 next year to provide practical help to eligible households, including pensioners.
