"Optus identified the issue within minutes through its network monitoring systems and immediately mobilised technical teams to restore services while activating established escalation processes and engaging relevant stakeholders," a statement from Optus said.

The spokesperson said 41 calls had been referred to Victoria Police for welfare checks, with the issue resolved about 3pm yesterday.
