Update - February 2026 In July 2024, Optus requested that the Commissioner stop investigating the complaint, and we provided submissions about why the complaint should continue in August 2024. In August 2025, the OAIC filed civil penalty proceedings in the Federal Court of Australia against Optus regarding this data breach (read more here). In October 2025, the OAIC advised that they were considering not investigating the representative complaint any further on the basis that the OAIC had now filed civil penalty proceedings. In November 2025, we again provided submissions about why the complaint should continue. We are now waiting for the OAIC to make a decision. We will provide a further update when this becomes available. The complaint alleges that Optus breached privacy laws by failing to adequately protect the personal information of its current and former customers.
