First, contact the travel agent or tour operator with whom you booked for assistance. If you’ve booked with an ATAS-accredited business, lodged a formal complaint with them and are not satisfied with their complaint resolution, you may submit a complaint to ATIA. ATIA manages complaints under the ATAS Code of Conduct and assesses whether a breach of the Code has occurred.

Request a chargeback: If you booked using a credit card, you may be eligible for a chargeback. Read more here.
Domestic flights: For Australian airline bookings, contact the Airline Customer Advocate, if you have a problem with a participating airline.
Take further action: If you are not satisfied with ATIA’s outcome to your complaint, or you choose not to lodge a complaint with ATIA, you can contact the consumer protection agency in your state or territory or a court or tribunal.
