Employee privacy

Federal law requires us to collect certain details about our customers and their family. We do this to maintain the integrity of the child support scheme. We understand these details can be sensitive and we work hard to protect the privacy of all our customers.

We must follow the Office of the Australian Information Commissioner’s Australian Privacy Principles, made under the Privacy Act 1988. They set the standards for our data collection, storage, security, use, disclosure and access.

We also have secrecy provisions in our legislation. These secrecy provisions restrict how information is collected or disclosed. Secrecy provisions can also apply to you.

To read how we collect, use and disclose information, see Chapter 6.3 of the Child Support Guide available on the Department of Social Services website.

These limit the communication of our customers' personal details, including when and who we can release the details to.
