You could try searching NAA for the unit Operation Record Books (diaries) which in most cases are recorded with the form number A.50 in the title. I would start with a search of something like
A.50, unit followed by
A50, unit but would leave out the year as NAA staff are often too lazy to type in the year correctly and will not correct their errors when they are advised of them.
They have known this file, and over 200 others, is incorrectly dated since 2019 and this screenshot taken today shows that they have not yet corrected it (or any others I have checked).

That search will produce documents like this that cover the unit history for the period of each diary. Some diaries are very detailed, some are very sparse.

If you know the crew names you could search for them with the word repatriation (if any were injured or killed) or martial (in case one or more were charged)
