ABC News Australia 10 July 2024: ACMA finds Telstra published details of more than 140,000 silent number customers over 10 years
The telecommunications regulator has found Telstra breached its licence after disclosing the details of more than 140,000 customers who requested to have their numbers unlisted.

Telstra has apologised to thousands of Australians who had their details published accidentally online by the communications giant.

The company said the release of the names, numbers and addresses of some unlisted customers was not the result of any malicious cyber attack and was a mistake.

“For the customers impacted we understand this is an unacceptable breach of your trust,” Telstra executive Michael Ackland said.

Telstra blamed a “misalignment of databases” and was working to pull the data off the internet.

Impacted customers are being contacted and offered free services to combat identity theft.
