It would be interesting to know the legal position of those who are due to depart Australia for Bali in regard to their losses in hotel bookings, loss of holiday time etc. ? Its not like at this time of year you can just book somewhere else.
Normally there is not much can be done if a flight is cancelled but in this case, if it is proved that their is a regulations problem it may get expensive for Tiger/Virgin.
If it was my holidays ruined and there were grounds,I'd certainly want expenses and damages.
