The facts appear to be correct. Qatar has every right to correct the story but so far don't appear to have even commented. Since the Qatar. Govt own both the airline and the airport then it is the Qatar Govts problem.
To a degree its also the Australian Govts problem. They have allowed Qantas who holds an RPT authority, to suspend international services, forcing desperate Australians to use any airline available.
The Australian Govt can respond by informing Qatar that they will not be renewing any bilateral aviation rights with Qatar.
