The last census was incredibly controversial for reasons that have not been well articluted by the media. The bulk of the media only really came on board in great numbers when the census site went down and caught the attention of the entire country but the privacy sector had been running a campaign for months prior to this event.

My submission to the Parliamentary Inquiry that followed the debacle was effectively a research project that included the results (and data) for an online survey that drew over 500 responses from the public. The survey focused on peoples' experiences with the 2016 census and their feelings around the de-anonymisation of the census.

However, as the submission elaborates, while it took untill 2016 for the government to find an ABS Head willing to de-anonymise the census, this was far from the first time an Australian government had tried. All previous attempts had failed in the face of massive public backlash.

In fact, the formation of Commonwealth privacy legislation in Australia is directly intertwined with past attempts to de-anonymise the census.

It was as a result of the protests of the 1970's censuses, that the government formed the Australian Law Reform Commission to inquire into the balance between the collection and storage of personal information in Australian censuses and the right of the individual to privacy:

The ALRC received a wide-ranging reference on privacy from the federal Attorney-General in April 1976. At the same time, public controversy arose in relation to certain aspects of the census to be held on 30 June 1976, therefore, the Attorney-General requested that the implications of the census for individual privacy be taken into account in the Commission's general reference. The ALRC released a discussion paper Privacy and the Census (ALRC DP 8) in 1978 and its first report, Privacy and the Census (ALRC Report 12), was tabled in federal Parliament in November 1979. (Quote from the ALRC website.)

My submission traces this history back over four decades, placing the current state of affairs in an historical context of previously failed attempts through government documents and media stories of prior events reminiscent of those occurring more recently.

Far from being dismissed, my submission was cited twice in the Final Report to the Inquiry into the 2016 Census and received many endorsements, including from the former Head of the ABS, Bill McLennan who wrote this in his own submission to the Inquiry:

I was impressed by the #Censusfail submission to this Committee. It very clearly showed some good analysis that would have helped the ABS to run a better Census if it had done such research before developing the Census proposal. It also saved me from explaining the current thrust in government with the Government Data Linkage Project, and its likely links to the Census.

Despite concerns about privacy and the lack of legislative authority raised during the Parliamentary Inquiry in 2016, the government's advice on the legality of using personal information supplied with censusus (for purposes other than statistics) was accepted. However, the government can not continue their plan to integrate our administrative data to supply to researchers without introducing a new law to make it legal. This law is The Data Sharing and Release Act.

It appears to be the argument of the ABS, that given the Data Sharing and Release Act will authorise the integration and access to administrative data that the Privacy Act 1988 allows this under Australian Privacy Principle 6 which allows disclosure where it is 'required or authorised by Australian law'.

To me this is nothing but a circular argument and underlines that this integration is not legally defensible without the new legislation but I'll let you make up your own mind.
