Airlines are looking to add flights to and from Bali as a change of wind helps to push away the ash cloud that has repeatedly closed airports over the past month.
The cloud is now expected to clear by early Monday afternoon.
Bureau of Meteorology forecaster Chris Davies told AAP: “Overnight we have started to see the winds shift so they are gradually turning to the north, which is pushing the plume of volcanic ash slowly to the south.
“So we are expecting during the course of the day for the ash to move south of the volcano rather than southeast, which will then clear it away from Bali.”
Flights may take longer to resume to normal.
“For the ash to clear from Bali, it will only take two to three more hours, but it will take more than that for airlines to start up again,” Mr Davies said.
Virgin Australia cancelled services in and out of Denpasar Airport on Monday morning but afternoon flights are under review.
Jetstar said it will operate a full schedule on Monday and will review its flights for early Tuesday.
“We are reviewing options for additional flights from Bali to Australia to get our passengers moving as soon as possible,” Jetstar said.
“Any additional flights will be subject to clear flying conditions and local approvals.”
Garuda Indonesia airline resumed flights to and from Denpasar Airport on Monday.
All other Indonesian airports are back to normal, except Banyuwangi Airport, which will remain closed until 4pm (local time) on Monday, Garuda said in a statement.
Mt Raung volcano has caused mayhem for airways since it began spewing corrosive, silica-based ash in early July.
