All Queensland government agencies1 must handle personal information in accordance with the Queensland Privacy Principles (QPPs) in the Information Privacy Act 2009 (Qld) (IP Act).
This guideline is based on and includes material from the Australian Privacy Principle guidelines developed by the Office of the Australian Information Commissioner.
Section 12 of the IP Act provides that personal information means information or an opinion about an identified individual or an individual who is reasonably identifiable, whether the information is true or recorded in a material format.
The individual does not need to be directly identified in the information for it to be personal information. It is sufficient if they can reasonably be identified by reference to other information.
Refer to Key privacy concepts – personal and sensitive information for more information.
QPP 2 provides that individuals must have the option of dealing with an agency anonymously or by pseudonym. However, an agency is not required to give individuals this option:
Agencies should ensure that, where appropriate, individuals are made aware that they can deal anonymously or pseudonymously with the agency.
Anonymity means that the individual dealing with an agency cannot be reasonably identified, and the agency does not ask them for personal information or information that might identify them. The agency should not be able to identify the individual at the time of the dealing or subsequently.
Anonymous dealings include an unidentified individual telephoning an agency to make general enquiries or seek general advice or information or lodging an anonymous complaint using an online form.
Agencies should ensure that their enquiries/customer service systems do not retain phone numbers or other identifying information where individuals are requesting to remain anonymous.
Pseudonymity means that the individual gives the agency a name, term, or descriptor instead of their actual name (a pseudonym).
Examples include using an email address that does not contain the individual’s actual name, a username that a person chooses when creating an online account or filling out an online form, or a caller to an agency who identifies themself using something other than their name, e.g., a nickname or the name of a fictional character.
The use of a pseudonym does not mean that an individual cannot be identified, particularly if the individual uses a consistent pseudonym or their email or phone number has been used in identified agency interactions. A pseudonymous individual may also choose to divulge their identity or may volunteer identifying information where doing so is necessary to implement their request or transaction.
However, the object of QPP 2 is to give individuals the opportunity to deal with the agency without revealing their identity. Personal information should only be linked to a pseudonym where required or authorised by law or a court or tribunal order, it is impracticable for the entity to act differently, or the individual has consented to providing or linking the additional personal information.
Agencies should ensure that anonymous and pseudonymous options are available to individuals, and that individuals are made aware of this option.
This does not apply where:
The steps an agency should take to draw both options to the attention of individuals will depend on the nature of the dealing between the agency and an individual. One method is to include this information in the agency’s QPP Privacy Policy.2 The privacy policy could set out:
If the agency has a procedure for managing pseudonyms and any linked personal information, this could also be included.
Other measures that can facilitate anonymous and pseudonymous dealing include:
An agency is not required to offer anonymous or pseudonymous option where it is authorised or required to deal with an identified individual. Generally, the authorisation or requirement must arise from a law, or orders from a court or tribunal,
If an agency is authorised to deal with identified individuals, the agency may have the discretion to allow the individual to be anonymous or pseudonymous. If the agency is required by law to deal only with identified individuals, there is no discretion.
The nature of any discretion, and whether it is appropriate to rely upon it, will depend on the source of the authority or requirement and the nature of the dealing.
Situations where an agency would only be able to deal with an identified individual include:
Where the agency can only deal with an identified individual, it should ensure it collects only the minimum amount of personal information required to meet its obligations. For example, if the individual is required to provide identification documents, the agency should determine if the requirement can be met by sighting the documents instead of taking a copy and putting procedures in place to do so. This aligns with QPP 3, which requires agencies to only collect personal information that is reasonably necessary for one or more of their functions or activities.3
Agencies are not required to allow anonymous or pseudonymous dealing where it is impracticable to deal with individuals who have not identified themselves.
It may be impracticable for an agency to deal with an individual who is not identified where, for example:
In limited circumstances it may be open to an agency to rely on the impracticability exception where the burden of the inconvenience, time, and cost of dealing with anonymous or pseudonymous individuals, or of changing existing systems or practices to include the option of anonymous or pseudonymous dealings, would be excessive in all the circumstances. However, this would generally only be a transactional, rather than an ongoing or permanent justification.
Unless an entity is required or authorised to deal with individuals who have identified themselves, agencies are expected to design and maintain information collection systems that incorporate anonymous and pseudonymous options.
Where it is impracticable to facilitate anonymous or pseudonymous dealings, agencies must ensure they collect only the minimum personal information required for the dealing. This is consistent with the obligation in QPP 3.
