Tasmania's popular winter festival Dark Mofo has been cancelled due to coronavirus concerns.

Dark Mofo was due to kick off in Hobart in June. Organisers say they have called off the event three months out because a last-minute cancellation would cost them millions of dollars and "likely end the event permanently".

The festival's creative director, Leigh Carmichael, said the decision was made with "deep regret and sadness".

"After a thorough risk assessment on the potential impact and disruption of coronavirus, we have been left with no option other than to move the current program to 2021," he said in a statement. "The implications of COVID-19 and subsequent travel, financial and logistical issues are beyond our control.
