The Australian government called the outage an "absolutely shocking failure" and has said it will seek answers from Singapore Telecommunications (STEL.SI), which owns the country's No. Singtel Group CEO Yuen Kuan Moon plans to meet Australia's Communications Minister Anika Wells this week, a spokesperson for the minister's office said. "Singtel takes this matter seriously and will extend full co-operation to the Australian government and authorities to address the Optus issue," a spokesperson said. A country-wide network outage in 2023, where emergency calls were also disrupted, triggered a Senate inquiry and the ousting of Optus' then-CEO Kelly Bayer Rosmarin. Rue, the Optus CEO, has said checks suggested the first outage could have been caused by human error and admitted procedures were not followed during the outage.
