Optus CEO Kelly Bayer Rosmarin is missing in action as the Singapore-owned telco faces its second massive crisis since she took the reins and the company was hit by the country's biggest ever hack.
Ms Rosmarin was dodging calls from government ministers after the Optus network crashed on Wednesday, cutting off phone calls, texts and internet access for 10 million customers.
Home Affairs Minister Clare O'Neil said she had been unable to get answers from Optus on the outage until the corporate giant finally released an update hours later.
And telecoms minister Michelle Rowland slammed the telco for not getting on the front foot by addressing the issue publicly.
