So for BM and admittance purposes sa airport and AU, 489 visas only need:

EntrycheckSA conditions (application min. 72 hrs prior to SA arrival, result via email within the same day of application)

Please note that SA requires 72 hrspre-arrival**, whereas Australia (in general) require 72-hrs pre-departure
Travel Declaration Form (must be submitted 72 hrs prior to departure)

Did I miss anything important?
** Probably a bit of useful info re: full quarantine in SA:
I am travelling to South Australia from overseas via another Australian state or territory, what are my requirements?
If you have been overseas in the last 7 days, you will be required to comply with ‘High Risk’ entry conditions on arrival to South Australia. This applies if you enter South Australia from another state or territory.
So baka if you land in QLD for example, and stay there for a week or so before moving to SA, then you might be considered not "High Risk" --- meaning a full 14-day quarantine might not be needed. Although, not entirely sure if non-Australians are considered "High Risk" by default. Please note that states such as Sydney/Melbourne are still considered COVID "hotspots" by other states.
So make of that what you will.
