Moniker,
Definitely not. All Jetstar passengers (ADL-DRW, MEL-DRW & BNE-DRW flights were all cancelled) were re-accomodated on other flights the next day or evening at the latest for no extra cost and in many cases on Qantas services. In addition to the scheduled service a second, ad-hoc MEL-DRW Jetstar flight was also dispatched on Saturday evening.
Those passengers who did not live at the port of origin were accomodated overnight.
All of the passengers were polite, friendly and were happy to be safe and dry in another part of the country.
With regard to Jetstar, always best to believe about 5% of the rumours.
