Australia telecom overhaul after Optus Triple Zero failure

Triple-zero (000) reliability reforms before bushfire season

Australia is moving quickly to shore up the 000 emergency call service ahead of the bushfire season by hauling telco chiefs to Canberra and fast‑tracking reforms. The Australian Communications and Media Authority (ACMA) has opened a compliance investigation, and Optus has appointed Kerry Schott to lead an independent technical review into the failures. The reforms build on proposals flagged after the nationwide Optus outage in November 2023 and signal a shift from after‑the‑fact reporting to proactive assurance for a service that must be available under extreme conditions.

India formally launched an indigenous 4G stack for state-run BSNL, alongside more than 97,500 towers announced from Jharsuguda, Odisha. Officials highlighted early reach metrics, noting that roughly 92,000 sites are active and connecting an estimated 22 million users. Telecom equipment sovereignty has become a board-level issue as operators de-risk supply chains, comply with trusted source mandates, and balance costs amid rising traffic and spectrum refarming needs.
