That incident, subject to an Optus probe and a federal communications watchdog investigation, sparked expectations of a meeting between Communications Minister Anika Wells and Singtel executives, who are visiting Sydney this week from Singapore. The Australian Communications Consumer Action Network wants Ms Wells to use licensing powers to mandate independent technical oversight of emergency and network reliability systems at Optus. "This would provide some assurance that there is strict oversight preventing further failures," network chief executive Carol Bennett said in a statement.
