Got my letter in the mail today, doesn’t seem that long ago that we had the last one…
Census date is 11th of August if you haven’t gotten the letter yet.
I note they’re definitely trying to spread the load this time by highlighting you can do it as soon as you get the letter rather than waiting for the actual date. Smarter move - albeit less amusing - than everyone doing it on the night, crashing the servers, and the ABS claiming it was a DDoS attack (I mean most of the country accessing your server does fit the definition, but they asked for it).
I stopped answering these things accurately when they left them tagged with your details.
If you want vulnerable people to fill out forms accurately you’ve gotta make sure that said forms can’t be used to round them up when the political winds blow the other way or an occupying force takes over. Governments keep records for a very long time and censuses have a history of being used for violence.
