Qantas previously had 26 return flights between Sydney and Wagga.

The airline announced the policy on Thursday morning, which included the suspension of all Qantas and Jetstar scheduled international flights from late March.

Qantas chief executive Alan Joyce said efforts to contain the coronavirus spread "have led to a huge drop in travel demand, the likes of which we have never seen before" and was "having a devastating impact on all airlines".

Wagga, Albury, Armidale, Coffs Harbour, Dubbo, Port Macquarie and Tamworth will continue to see "around 12 return services per week" from the QantasLink regional service.

"[Qantas group] will maintain connectivity to almost all Australian domestic and regional destinations that Qantas, QantasLink and Jetstar currently operate to," the airline's statement said.

"The 60 per cent reduction in capacity will come mostly from a significant reduction in flight frequency, but also route suspensions and postponing a number of new route launches."

Two thirds of Qantas' workforce will be stood down "until at least the end of May 2020".

"We're in a strong financial position right now, but our wages bill is more than $4 billion a year. With the huge drop in revenue we're facing, we have to make difficult decisions to guarantee the future of the national carrier," Mr Joyce said.

"The reality is we'll have 150 aircraft on the ground and sadly there's no work for most of our people. Rather than lose these highly skilled employees who we'll need when this crisis passes, we are instead standing down two-thirds of our 30,000 employees until at least the end of May.

"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."
