Just for the record.
I believe that I am correct in saying that Civil Aviation in Australia never used ISB for point to point HF coms.
We used AM voice up until the 1960s, then SSB, until it was gradually replaced by satellite FM FDM.
The SSB networks were relatively extensive.

I also think Defence just used SSB, and at one time had considerable numbers of Collins HF80s.

I think OTC Australia used some ISB.
