Between 2010 and 2013 analog free-to-air TV signals are being switched off and replaced with digital-only signals. Once the switchover is complete, you will need a TV with a digital tuner built-in, or a digital set top box to watch free-to-air digital television on your existing analog television. Click on the links below to find a set top box or a TV.
For more information on the digital switchover, visit the government's Digital Switchover website: http://www.digitalready.gov.au
