By now, most households will have received a letter in their mailbox with instructions on how tocomplete the Census. Emily Walter, Census national spokesperson, says if you know where you will be on Tuesday 11August, you can complete your Census early. “While many households have completed their Census already, we’re urging those who haven’t todo so as soon as possible,” Emily says. Everyone in Australia on Census night must be included on a Census form. Data from the Census is used to build a picture of what communities across Australia need.
