Telstra mobile customers in Griffith are being advised of planned network disruptions as the telecommunications company undertakes upgrade works to improve services in the area.

The mobile base station servicing Griffith will be temporarily switched off whilst upgrade works are underway, affecting mobile services for Telstra customers during specified periods. Telstra mobile customers will receive text messages advising them of the upcoming work.

The planned outages will occur during the following times: from 7am Friday, 5 December to 5pm Tuesday, 9 December 2025, and for up to eight hours between 8am and 6pm on Wednesday, 10 December 2025.

Landline services, NBN and satellite internet services, and mobile coverage from other providers will not be impacted by the upgrade works. Importantly, any calls to Triple Zero from a Telstra mobile when the site is off air will automatically connect to another mobile network if available, ensuring continued access to emergency services.

To minimise disruption during the outage periods, Telstra is encouraging customers to utilise Wi-Fi Calling, a free setting available on most popular mobile phones that allows users to make and receive mobile calls whilst connected to Wi-Fi. This feature will enable customers to continue making calls and sending texts during the service disruption.

Business owners are being encouraged to speak with their banks about connecting their EFTPOS terminals to their NBN or Wi-Fi connection to prevent delays in processing transactions during the mobile network outage.

Customers can stay updated on the outage and receive further information by visiting the Telstra website at www.telstra.com.au/outages.

The upgrade works form part of Telstra's ongoing investment in improving mobile network infrastructure and service quality across regional areas.
