Air Australia positioned itself as a low cost carrier (LCC) and was directly competing with the likes of Jetstar and Tiger Airways. It offered low fares to domestic and international destinations, notably Hawaii, Thailand, and Bali. When they were placed into administration many passengers were stranded overseas or left holding worthless tickets.

What will Travel Insurance cover?
First place you need to check is the PDS. This spells out the terms and conditions of your travel insurance policy. Then go to the travel insurance company's website and check for any updates (or call them). If there are exceptions in place or your policy doesn't provide coverage you won't get any help from your insurance company.
Otherwise you will be covered for (up to the policy limits):
- Cost of re-booking flights
- Hotel accommodation
- Food and other incidentals
Remember that you will need to pay an excess for claiming. If you have future flights booked it might be best if you do a charge back via your credit card (if you paid with one) as this won't be reduced by an excess.
