As Australia's 3G networks are retired, 4G phones without VoLTE and some regional customers are likely to be impacted.
All three major telcos have been warning customers to make sure they upgrade from 3G-only devices, but also to check if their 4G and 5G devices have something called Voice over LTE (VoLTE), so that they don't get caught out when 3G networks shut down.

The 25 most common devices which may be affected
According to the Australian Mobile Telecommunications Association.
I still get 3G sometimes 50km from the Melbourne cbd, despite having a 5g capable phone direct with Telstra. This cut off is a problem in these areas where reception is terrible.
