HIDDIN Privacy, Data Access & Ethics


The collection of data and all associated data access projects must comply with the Privacy Act 1988 and state privacy legislation. All data must be treated with confidentiality.

The Census data must be stored in a safe and secure location that can only be accessed by identified personnel. Only the Census investigators listed under the section ‘Contacts’ and research staff employed specifically for the Census project can access the database.

All data must be stored in a de-identified manner. Data collected for the longitudinal study must be stored separate from the linkage log.

An individual should not be identifiable in the publication or presentation of data from the Census.

Access to data by external organisations must comply with this privacy statement.


Access to the de-identified census data will only be approved for non-commercial purposes (e.g. research). Please review the Data Management and Access Policy (PDF 1.1 MB). To submit a Data Access Application.


The census project, including the longitudinal study, has received ethical approval from the University of Tasmania Social Science Human Research Ethics Committee (#H0017281).
