Is the Australian Government going to pass any laws pertaining to this sort of thing? They are mulling it over in the USA after having several very nasty turn of events with pax being left overnight on u/s aircraft on numerous occasions in the past year(in one instance in Hawaii they turned off the APU). It all came to a head recently with JetBlue handling a major snow storm "Jetstar Style" by leaving everyone stranded in the JFK terminal. Really if you are going to be stuck anywhere overnight the airline should be putting you up in a hotel. QF will and have done it in the past, maybe it should become law.
