Registered declaration voting

Electoral Commission of South Australia maintains a register of voters who are permanently prevented from attending a polling booth and meet certain criteria. These voters are called registered declaration voters for state elections and general postal voters for federal elections. 

Once registered, you do not need to re-apply for future elections.

To apply to become a registered declaration voter you must meet one of the following criteria that prevent you from attending a polling place on polling day:

  • Distance – you are enrolled at an address more than 20 km away from any polling place
  • Illness – you are a patient at a hospital or nursing home and unable to travel to a polling place
  • Infirmity – you are unable to travel to a polling place due to being infirm or seriously ill at home
  • Caring for others – caring for a person who is seriously ill or infirm
  • Physical disability – you are unable to sign your name due to a physical incapacity
  • Religion – your religious beliefs or membership of a religious order prevent you from attending a polling place on polling day
  • Overseas – you are an elector who is registered as an overseas elector
  • Silent elector – you are an elector whose address has been suppressed

To become a registered declaration voter, you can:

Silent electors

Silent electors have their address suppressed from the electoral roll. If you believe that your safety or the safety of your family members may be at risk by having your address on the electoral roll, then you can apply to become a silent elector.

People applying to be silent electors can request their ballot papers for all elections to be sent to them by post.

For more information and to access the silent elector application form, visit the Australian Electoral Commission's silent electors page.
