Queensland Competition Authority Act 1997

If a document is produced to the authority for an investigation, the authority may—

inspect the document; and

make copies of the document if it is relevant to the investigation.

Also, the authority may take possession of the document, and keep it while it is necessary for the investigation.

While it keeps a document, the authority must allow a person otherwise entitled to possession of it to inspect or copy the document at a reasonable time and place the authority decides.
