Optus phone and internet outage affects millions across Australia

Optus has been hit by a nationwide outage, with its mobile phone and internet services down for millions of Australian customers and businesses.

On its website early on Wednesday, Optus said its engineers were investigating a network fault affecting customers.

Mobile phone users were unable to make or receive calls and mobile internet services were down.

On the social media site X, formerly known as Twitter, Optus said it was working to restore services as a priority.

Train services were also interrupted in Melbourne, reportedly due to the Optus outage, with ongoing delays expected.
