Telstra has been ordered to pay a $277,200 penalty after an Australian Communications and Media Authority investigation found failures in identity verification and fraud protections linked to mobile number fraud. Between January and October 2025, Telstra failed to follow required identity authentication procedures in 15 unauthorised SIM swaps. The investigation also identified 13 cases in which agents did not provide additional protections to customers who had raised concerns or were known to be at risk of fraud. ACMA Authority Member Samantha Yorke said the failures left customers vulnerable to SIM swap scams and other forms of mobile fraud. Customers reported combined financial losses of at least $39,500, according to the authority. In addition to the penalty, Telstra has entered court-enforceable undertakings to strengthen fraud prevention procedures and improve training for customer-facing staff. The action followed earlier enforcement against the company and is the seventh announced under the ACMA’s mobile number fraud crackdown, which has resulted in more than $5 million in penalties.
