Virgin Blue says last month's outage of its reservations, check-in and operating systems has cost the business between $15 million and $20 million.
The computer system crash on September 26 caused severe disruption to flights and passengers for 11 days.
Virgin Blue staff nationwide were forced to process check-ins by hand, while many flights were cancelled.
Thousands of passengers were delayed and many had to be put up in hotels overnight.
Virgin Blue says it will "actively pursue all avenues" to recover the cost of the crash of its Navitaire/Accenture computer system.
