Free-to-air TV channels changed frequencies on Monday, requiring people to retune their digital TV, set-top box or digital TV recorder to get them back.
Retuning is done using the remote. For most systems, viewers should press the menu button on the remote, look for settings such as channels or auto-tuning, then follow the prompts.
Residents who receive their TV signal from the Ulladulla or Illawarra TV towers retuned earlier this year but may now need to retune again.
Viewers having difficulty retuning their equipment should check their manufacturer's handbook or manual for instructions on how to retune, ask a friend or family to help, visit the retune website or call the Digital Ready Information Line, 1800 20 10 13, 8am-10pm, seven days a week.
