Tiger Airways Australia's operations are likely to be suspended until 5 August, even though the carrier is confident that it is on course to resume services and meet the conditions imposed by the country's regulators.
The Civil Aviation Safety Authority of Australia (CASA) suspended Tiger's operations on 1 July because of safety breaches, and this was extended to 1 August pending a court hearing.
That will carry on until 5 August as tries to meet CASA's requirements, said the airline's Singapore-based parent Tiger Airways Holdings.
"Tiger Airways Australia and CASA have been working constructively to address the concerns raised by CASA since this date," it said.
"CASA has today issued Tiger Airways Australia with a set of formal conditions that the airline must comply with, some of which must be satisfied prior to the reintroduction of their domestic flights.
"As a result of the progress made since 1 July 2011, Tiger Airways Australia is confident that it can comply with these conditions and expects to resume services in the near future."
Tiger did not provide any details on what these conditions were. More information could be available on 4 August, when Tiger releases its first quarter financial results.
