Telstra has received about 8,000 compensation claims and paid more than $100,000 following its nationwide mobile outage on July 8, 2026. However, compensation is not being issued automatically to all 8.8 million customers contacted after the disruption.
Telstra chief executive Vicki Brady told a Senate inquiry on July 17 that many successful claims had resulted in account credits. Customers seeking payment for lost income or additional expenses must provide evidence connecting the loss to the outage.
Who can claim compensation?
Residential and small-business customers can ask Telstra to assess their circumstances. There is no standard payment because the financial and practical effects differed between accounts.
Customers can use Telstra’s official online complaints form or call 1800 242 728.
The complaint should identify the affected account or mobile number, when the service failed and what loss or serious inconvenience occurred. Customers should retain their complaint reference and copies of all supporting documents.
People using Boost Mobile, Belong, ALDI Mobile, Tangerine or another provider operating on Telstra’s network should contact the company that bills them.
Evidence businesses should provide
Businesses claiming lost revenue should provide a clear calculation supported by failed payment reports, cancelled orders, missed bookings, customer refunds, invoices or receipts for temporary services.
Sales records comparing the outage period with normal trading may provide additional context. Businesses should also explain steps taken to limit losses, such as switching to Wi-Fi, accepting cash or using another network.
A broad estimate may not be sufficient. Telstra can request further information before deciding whether to provide a payment or account credit.
What caused the Telstra outage?
The Senate inquiry heard that the failure began during maintenance on a 15-year-old timekeeping server at Telstra’s Exhibition Street exchange in Melbourne.
After restarting, the device incorrectly reset its date to 2006 and distributed inaccurate timing information across parts of the mobile network. That caused authentication failures affecting calls and data sessions.
At the incident’s peak, approximately 45% of Telstra mobile calls and data sessions were affected. The company said the outage was not a cyberattack.
The equipment supplier had advised Telstra in 2022 and January 2026 to install a software update, but it was not applied. An undocumented network design change also allowed the incorrect timing data to spread.
Telstra acknowledged that installing the update or replacing the server would probably have prevented the outage. The inquiry heard that replacement equipment would have cost approximately $30,000.
Outage and restoration timeline
Telstra detected intermittent mobile calls and data at approximately 4.30am AEST on July 8. Most services were restored by about 4pm.
A related emergency-calling problem continued after the main service recovered. Telstra implemented an additional fix by 12.30pm on July 9.
The outage disrupted card payments, ride-hailing services, food deliveries and some electric-vehicle chargers. Regional trains were suspended in Victoria, while services in New South Wales were interrupted.
The payment problems reflected the dependence of modern businesses on connected terminals, as seen during the Westpac EFTPOS disruption in Australia.
How many Triple Zero calls failed?
Telstra reported that 58,835 Triple Zero calls connected successfully on the first attempt, while 604 did not. Hundreds of welfare checks were conducted to establish whether affected callers still required assistance.
Phones normally attempt to use another available network when an emergency call cannot connect through the customer’s provider. During the outage, some callers received an error or experienced a delay before that process began.
The incident renewed scrutiny of emergency-call safeguards examined during the Optus Triple Zero outage inquiry.
ACMA investigation
The Australian Communications and Media Authority is investigating Telstra’s compliance with emergency-call, customer-notification and welfare-check obligations.
The regulatory investigation is separate from the Senate inquiry and Telstra’s internal review. No final finding or penalty had been announced as of July 18.

What if a claim is rejected?
Customers must first allow Telstra or their own provider to address the complaint. If a claim is rejected, delayed or not resolved satisfactorily, it can be escalated to the Telecommunications Industry Ombudsman at no charge.
The ombudsman can consider documented business losses, lost income, reasonable alternative-service expenses and significant inconvenience. Customers should provide their complaint reference, evidence and the provider’s response.
Anyone receiving an unexpected compensation offer should verify it through Telstra’s official channels. Passwords, banking credentials and one-time security codes should never be given to an unsolicited caller.
