Most recently, New Zealand’s COVID Tracer app was revamped where it now utilises a bluetooth based exposure notification framework used by Google and Apple whilst Australia continues to use the COVIDsafe app which also uses bluetooth but with a different framework. With the recent announcement of the Trans-tasman bubble set to launch in the first quarter of next year where Australians and New Zealanders can travel across the Tasman without having to quarantine, questions will be raised on if we need a contact tracing app for this travel bubble. To discuss more Dr Suranga Seneviratne, Lecturer in Security in the School of computer science at the University of Sydney joined us.
