Optus, Australia’s second-largest telecommunications company, suffered a significant outage on Sunday, affecting emergency call services for the second time in just 10 days. The latest incident, caused by a faulty mobile phone tower in Dapto, impacted around 4,500 customers and is particularly concerning given the previous outage on September 18, which led to four deaths as customers were unable to reach emergency services, according to India Times, South China Morning Post, and Reuters.

The Australian government is demanding transparency and accountability from Optus regarding these outages. Communications Minister Anika Wells expressed her frustration and stated there is a "very serious lack of confidence" in the company’s ability to provide reliable emergency services, as reported by South China Morning Post and Reuters. Following the incidents, Optus has stated that it is conducting an internal investigation to identify the causes of these failures.

Optus, a subsidiary of Singapore Telecommunications (Singtel), has come under intensified scrutiny for not only the recent outages but also for previous failures, including a data breach in 2022 that compromised the data of millions of Australians and a US$66 million fine in 2023 for selling unnecessary products to vulnerable customers. The firm’s integrity remains in question as it struggles with governance issues, according to Channel News Asia and Channel News Asia.

Singtel Group CEO Yuen Kuan Moon emphasized the need for change at Optus after meeting with Australian officials to address the fallout. He acknowledged that the prior outage could be tied to procedural errors and stated, "It takes time to transform a company," reflecting the ongoing challenges faced by Optus in regaining public trust, according to Channel News Asia and Channel News Asia.

The series of outages has resulted in increased calls for stricter regulatory scrutiny and the possibility of sanctions against Optus. Experts note that these recurring issues could expose the company to significant fines and even legal challenges, reinforcing the critical nature of accountability in the telecommunications sector, as noted by Channel News Asia and Channel News Asia.
