The comments around Qantas subsidising Jetstar I struggle to believe, unless someone has solid evidence to prove it... Jetstar runs its own P + L and yes, initially would have been provided with some working capital to start-up and all returns go back to Qantas, so I am not sure how Qantas subsidises it. All Qantas Group companies operate as independent business and are responsible for their own P + L...
Qantas is audited and has rigid corporate governence. I am not sure how they'd get away with "creative accounting" by the auditors which I think are PWC.
