It contains the keys to your 2026 Census, which is happening tonight, Tuesday, August 11. That means the Australian Taxation Office, Centrelink, and the Department of Home Affairs cannot access your Census form. Simply head to the official ABS website, enter those details, and you are ready to go. If your home will be completely empty tonight, you just need to let the ABS know via their website or phone line. Refusing to complete the Census can result in fines of up to $364 for every day you fail to comply.
