Qantas and Jetstar will suspend all international flights from late March as a result of the coronavirus pandemic.
The airline will also stand down two thirds of its workforce until the end of May.
The decision comes after the Federal Government revised its travel advice to recommend against all overseas travel from Australia.
The airline told the ASX regularly scheduled international flights will continue until late March to assist with repatriation efforts, before being suspended until at least the end of May.
There will also be a 60 per cent reduction in domestic flights, with more than 150 aircraft temporarily grounded.
More than 150 aircraft, including all of the airline’s fleet of Airbus A380s and Boeing 787s will be temporarily grounded.
Qantas will "stand down" the majority of its 30,000 employees, and will guarantee all employees at least four weeks of paid leave.
Workers will be given additional support mechanisms including leave at half pay and early access to long service leave.
But the airline admits periods of leave without pay will be “inevitable” for some of its workers.

“This is a very hard set of circumstances for our people, as it is for lots of parts of the community right now,” Qantas CEO Alan Joyce said in a statement.
“We’re in a strong financial position right now, but our wages bill is more than $4 billion a year.”
“Most of our people will be using various types of paid leave during this time, and we’ll have a number of support options in place.”
“We’re also talking to our partners like Woolworths about temporary job opportunities for our people.”
Qantas Management and the Board will also go without pay until at least the end of the financial year, joining the Chairman and the CEO.
