The census occurred on 9 August 2016. For the first time, the ABS the census was by default filled out online, claiming it expected more than 65% of Australians would be completing the census online. Reflecting this new preference, the tagline of the ad campaign for the census was the rhyming slogan "Get online on August 9". Across many regions, paper forms were no longer delivered by default to homes, and households that wished to complete a paper census had to order such forms via an automated hotline. Letters were sent to each dwelling with unique code numbers that people would need to either login to the census website or order a paper form if they preferred. By census night, many households had still not received such a letter. Contrary to previous years where censuses were both delivered and retrieved from households by dedicated census employees, in 2016 most of the paperwork relating to the census was delivered from and to the ABS by Australia Post.
