The Australian government is working with the states and territories to add COVID vaccination certificates to each jurisdiction’s check-in apps, arguing the approach was necessary as public health orders and check-in QR codes are controlled by the states.

NSW began its trial of vaccination certificates in its Services NSW app this week, although the site of the two-week trial and how it will work is still not public, and the trial period extends beyond the October 11 opening up day for fully vaccinated people in NSW announced yesterday.
