KEY CONTEXT *Optus has been under intense political and regulatory scrutiny since a 2022 cyber attack exposed millions of people's personal details to criminals. *The event resulted in a sweeping overhaul of Australia's cyber-readiness and response rules including mandatory reporting and increased fines for prevention failure. *In 2023, millions of Optus residential and business customers were without phone or internet for most of a day after a routine software upgrade inadvertently sent its entire network offline until it was rebooted manually. *Rue told parliament the September 2025 emergency line outage was caused by human error during a routine firewall upgrade which meant that traffic wasn't diverted before locking the equipment that was being upgraded.
