Qantas was not involved in anything to do with Compass Mark 1 as at that time they were purely an international airline - they weren't allowed to fly domestically until they purchased Australian (TN) Airlines late in 1992 (approx 10 months after Abeles had arranged for his mate the PM to pull Compass's AOC.

In the world of business, airlines are considered very poor return on the sums invested. Qantas has many billions invested in equipment and infrastructure and its recently reported "record" profit did not impress serious investors as in the last 3 years QF has been spending billions in an expansion program and with this increased capital equipment they had expectations of a much larger profit. a good comparison is QF made under $700million profit from just under $12 billion in revenue - Commonwealth bank made $4 billion profit from the same revenue. The only way to truly compare the performance of airlines based in Australia is to look at profit versus capital invested - it might turn out that an operator such as Air North gets much better returns.
