ACT offers Victoria free contact tracing app hailed as key to territory’s COVID defence

Peter O’Halloran, ACT Health’s Chief Information Officer, said the app was one of the territory’s key defences against a potential reintroduction of COVID-19. He said other states had shown strong interest in using the software which would be provided to other jurisdictions for free.

“This is one of our key steps to keep open if there’s another wave of cases. This will ensure we’re ready,” Mr O’Halloran said, adding the app had been downloaded more than 25,000 times and more than 2000 check-ins were recorded each day. More than 2.5 million QR check-ins were recorded on a single day in New Zealand in September.

Mr O’Halloran said ACT authorities settled on the QR scheme to ensure its contact tracing was as speedy as possible. When the territory was grappling with cases earlier this year (it has been almost virus-free since July) authorities struggled to obtain timely information from businesses using paper-based attendance logs that were sometimes lost or soiled with drinks, he said.

Burnet Institute epidemiologist Professor Mike Toole said Victoria should adopt a centralised QR app to minimise the time spent by contact tracers collating information. He said Victoria, as it reopened after a months-long lockdown, needed to implement systems that facilitated the quickest and most precise contact tracing.

“It’s an excellent idea … and it’s worked well in South Korea since May,” he said.

“It’s going to be really important from now on heading into summer because we want to have the tightest possible contact tracing.”

Professor Toole said the system should be used by businesses that host more than about 10 people at any one time because, he said, these businesses would likely be less diligent in writing down names manually given the high volume of customers.

He said using QR codes would assist the government in its attempt to increase the amount of “upstream” or “backwards” contact tracing where authorities find contacts exposed to an infected person even before they became infectious. The labour- and time-intensive strategy seeks to locate the “index” case – the original spreader in a cluster.

Jeff Feldman, a developer involved in the creation of the ACT app, said the software underpinning QR code apps was simple and cheap. He said the app could be rolled out in Victoria in less than a week.

Mr Feldman – whose Victorian-based company Arden Street Labs provides digital COVID-19 screening systems to hospitals – said data was stored on servers that were rapidly accessible by contact tracers. These contact tracers would otherwise need to deal with any number of different attendance log systems used by businesses involved in a cluster, some of which may use their own digital systems, he said.

“You know where the data is, you know it’s secure and private, and you know it’s accessible,” he said.

“One of the key things we need to do as we open up is leverage everything we have at our disposal.

“Lockdowns are useful as a short-term stopgap but during that time we need to build and prepare and develop novel solutions to help prepare.”
