National Archives of Australia had, for some years (and after access assessment), offered digitised Service files on request (in more recent years, for a fee).

From 2019, the NAA has been funded to digitise WW 2 personnel service records: for the RAAF, that means the Officer (A9300) and NCO/OR (A9301) record of service files.
The program was expected to be complete in 2023.
Delayed by COVID, it continues and progress to date across the Services is given here:

So there is a fair body of RAAF A9300 and A9301 record of service files to go.
As the program progresses, some Open files may therefor not be immediately available to view.
NAA Canberra Research Centre is open for visit but bear in mind that the available WW 2 RAAF files are held not in the Research Centre but in an off-site repository.
On request to retrieve a file, assuming it is available, it may take 1 to 5 days to reach the Research Centre.
Request to review any Not Yet Examined file for possible Open status may take 90 days.
