Australian states are introducing digital drivers licenses and in November 2019 the Marriage Law and Celebrants Section of the AG office issued this statement on the new digital licenses in NSW, which would apply to other states as they progress into the future like Queensland has today and South Australia before it:

As a marriage celebrant you are able to use a digital driver’s licence as evidence of identity in the same way as you currently use a driver’s licence issued as a plastic card. The NSW Digital Driver Licence is legal for use across NSW and is accepted by NSW police, however, they are optional and not considered a replacement for the plastic card at this time.
