More than 6000 stranded travellers will be back in Australia from Bali within a day if flying conditions remain clear.

Jetstar and Virgin Australia have resumed services to the Indonesian resort island after a cloud of volcanic ash twice forced the closure of Denpasar airport over the past week.

Jetstar ran 19 services in and out of Bali on Monday, with about 2000 travellers to have returned to Australia by Tuesday morning. A further 2400 will be back by Wednesday morning.

Virgin Australia has already brought home 350 passengers on two flights that departed on Monday. That number will have climbed to about 2000 by early on Wednesday.

Assuming flying conditions remain clear, Jetstar will operate its usual eight scheduled services to and from Bali, but will also run 10 extra flights.

Qantas, which owns Jetstar, is helping the smaller airline free up its aircraft for the Bali run.

Qantas planes will be used to service some of Jetstar’s domestic routes to help the airline get its passengers back from Indonesia quicker. Jetstar has put some Boeing 787 Dreamliners on the route, with a carrying capacity of 335 passengers.

Virgin Australia will also operate 18 flights into and out of Bali on Tuesday, including eight additional services.
