Airline Regional Express has forecast a full-year loss of $15 million due to Victoria's coronavirus outbreak.
The airline, also known as Rex, had been on course for earnings to break-even but on Wednesday said it now expected a statutory loss before tax of $15 million.
A number of states and territories have required travellers isolate for two weeks after arriving from Victoria, which has hurt travel demand.
Rex said customers whose flights were cancelled due to the virus were being offered credit refunds.
Shares were up by 0.4 per cent to $1.26 at 1125 AEST.
