WA Police issue a warning that calls to Triple Zero can be disrupted due to a nationwide Telstra outage. The disruption affects people attempting to contact emergency services, according to the reports. Police advise the public to be aware that calling the emergency number may not work reliably while the outage is ongoing. The reports do not specify the cause of the outage, the number of affected callers, or any alternative contact method in the available text. Both outlets describe the same situation: a Telstra network outage that interferes with the ability to reach Triple Zero. The warnings are directed at residents in Western Australia, but the outage is described as nationwide. The information is presented as an urgent public notice from police to ensure people understand the potential difficulty contacting emergency services during the telecommunications disruption. The reports indicate the issue impacts attempts to place Triple Zero calls rather than emergency response operations more broadly, but details are limited in the excerpts provided.
