The census website has been restored more than 40 hours after being taken down due to cyber attacks and a hardware failure.
The online form became available on Thursday afternoon, after the Australian Signals Directorate gave the all-clear.
"The census website is now available. Thanks for your patience. We apologise for the inconvenience," the Australian Bureau of Statistics tweeted at 3pm AEST.
The ASD has also told the Australian Privacy Commissioner Timothy Pilgrim that the denial-of-service attacks on the site had not accessed or extracted any personal information.
"On the information provided to me by ASD, I am satisfied that personal information was not inappropriately accessed, lost or mishandled," he said in a statement.
Mr Pilgrim said the ABS decision to shut down the census site was "a pro-privacy precaution".
The government is now hoping millions of Australians will complete their forms in order to provide enough information for a statistically useful census.
Remember, you have until September 23rd to complete your census but it must reflect the details as of 9th August.
