WA Police conduct an urgent welfare check in Perth’s southern suburbs after a caller reports being affected by a Telstra network outage and is unable to reach emergency services via triple-0. Both outlets report that the incident involves a person who cannot make contact with triple-0 due to the telecommunications disruption. Police respond by locating the caller and completing a welfare check to confirm their safety. The reports attribute the problem to the Telstra network outage, which disrupts phone access to emergency numbers. The outlets do not provide additional details on the extent of the outage, how widespread the impact is, or whether alternative communication methods were used. No injuries or further outcomes are mentioned beyond the completion of the welfare check.
