Telstra says its internal controls were not good enough after an outage, according to a written submission lodged hours before a Senate hearing on Friday. The company acknowledges that a software update was not applied to the specific device that triggered the disruption. The submission indicates that the lapse occurred in Telstra’s process for updating or maintaining the affected equipment, rather than being linked to a different cause. By stating that its controls failed to ensure the update was installed, Telstra frames the issue as a deficiency in governance or safeguards that are meant to prevent similar failures. The three reports in this set all describe the same core disclosure: Telstra admits that the device involved did not receive the relevant software update, and it characterises its controls as insufficient. The Senate hearing is presented as the setting in which Telstra’s evidence is provided, with the submission serving as a formal statement of its position ahead of questioning.
