"Simon's experience in the communications and telco industries in Australia and abroad ensures we can enable organisations and their employees to connect, collaborate, and ultimately better service their customers at this time of heightened need," said Avaya vice president for East Asia and the Pacific Sami Ammous.
"With a renewed local strategy focused on long-term, high value relationships with customers and partners, our ANZ business is poised to provide the market with tailored solutions that make them truly agile so they can adapt quickly, and deliver exceptional experiences for their teams and customers under any conditions."
Vatcher joined Avaya from Optus, where he held several senior roles, most recently that of vice president.
He previously served two stints at Excellis as managing director, worked as a client executive at Logica, held director-level roles at Fujitsu, and as technical services director at JPMorgan Chase.
Earlier in his career Vatcher worked in technical roles at Eurobell, Telewest and Bristow Helicopters.
"My priority is to introduce data-driven growth strategies so that our customers and partners can not only rapidly deploy our comprehensive communication solutions but maximise the benefits they gain from those capabilities in shorter time scales," he said.
