Overview
- Optus confirmed a Dapto, NSW tower fault on Sunday disrupted services for about 4,500 customers between 3:00am and 12:20pm, with nine triple‑zero calls failing.
- The telco said police welfare checks verified all affected callers are OK, service has been restored, and the cause is still under investigation.
- The incident is the second triple‑zero failure in 10 days, following a September 18 outage during a firewall upgrade that blocked hundreds of emergency calls and has been linked to multiple deaths.
- Optus has launched an independent review led by Kerry Schott, while ACMA is conducting its own investigation into the earlier nationwide failure.
- After meeting Optus CEO Stephen Rue and Singtel CEO Yuen Kuan Moon, Minister Anika Wells cited a serious lack of public confidence, called for an external accountability partner, and fielded fresh calls for mandated technical oversight and answers on why the ‘camp‑on’ failover did not work.
