I’m no expert on Australian corporations law, but I would think:
QANTAS AIRWAYS LIMITED
ACN 009 661 901
Registration Date: 18 January 1934.
Is complying with the extract you quote from the QANTAS SALE ACT 1992.
I think you’d be pulling a long bow to suggest that a separate autonomous company, with it’s own independent Board and Management - albeit wholly owned by Qantas - was legally in breach of the Act.
Morally perhaps, but I doubt legally in breach of the Act. And Courts don’t deal with morals where companies are concerned.
