If you are enrolled to vote in Queensland you will receive a Voter Information Card in the mail (and electronically** if you enrolled with an email address) from the Electoral Commission Queensland (ECQ), prior to the start of early voting.
**Electronic voter information cards
If you enrolled to vote in Queensland and included your email address on the electoral roll you will also receive an electronic Voter Information Card. This version works the same way and has a QR code unique to you. When you arrive to vote, you can show this to election staff. You can bring either card with you when you vote, whichever you prefer.
