Australian travellers heading to and from Bali will face another day of disruption on Tuesday as airlines closely monitor the ash cloud.
More than 400 flights to and from Bali were cancelled and nearly 60,000 travellers have been stranded.
The
normally bustling airport on the Indonesian resort island of Bali is a
near-ghost town, dotted by anxious Australian tourists desperate to get
home.
The airport's initial closure was for 24 hours until early Tuesday, but it is expected to stay closed for another day.
On Monday night, tourists settled down for the night on makeshift beds on the airport's dusty floors.
Some
were considering making the more than 10-hour journey to Surabaya and
catching a series of flights across Indonesia back to Australia.
All are frustrated by what they say is a lack of updated information from their airlines about what happens next.

The
first Janeen McKay heard about flight cancellations was in a text from
her brother back in Australia as she was on her way to Bali's airport.
'I had nothing from Jetstar, they had my mobile number,' the West Australian told AAP.
After a 12-hour wait at the airport, she's now been told she won't be able to get home until Saturday at the earliest.
'We had a really nice time in Bali but then we get here and this has just ruined it,' Ms McKay said.
'Why does it take five days to get us out of here? Not very happy.'
Ms McKay, an office manager, is keen
to get back to Geraldton, north of Perth, to take over the care of her
elderly mother from her sister, a nurse, who's needed back at work on
Thursday.
Veronika Naberezhnova is also non-plussed.
'It's a bit annoying,' the Department of Human Services worker said.
'My family's waiting there (in Sydney) as well, they're all waiting, they're all stressed.'
On
the other side of Bali, at Sanur beach, the distant crackle of
lightning and an afternoon rain shower were the only annoyances for
tourists lounging on sun beds and sipping cocktails.

Jetstar has cancelled all flights to and from Bali and will reassess the situation on Tuesday
For them, the airport's closure means an extended holiday.
'What's
to be annoyed about, getting stuck here,' said Simon Allan, whose
flight to Perth was cancelled because of the ash cloud.
'We
have no control of nature and we'll just go with the moment and see
what happens tomorrow,' his partner Deborah Flynn told AAP.
Scientists
say Mount Agung's volcanic activity could escalate further over the
coming days meaning planes could stay grounded with thousands unable to
fly in or out of Bali.
Carriers Jetstar and Virgin Australia will reassess the situation later on Tuesday.

Jetstar has cancelled all flights to and from Bali, as has Virgin Australia.
Jetstar acknowledged 'further disruptions are possible this week depending on weather conditions'.
Affected
Jetstar customers have been given the option of flying to destinations
including Phuket, Singapore, Fiji or Tokyo at no additional cost.
Other major airlines are all monitoring the situation but are unable to fly until the massive ash cloud dissipates.
Flights
from other Indonesian airports were experiencing delays on Monday
because Bali's Gusti Ngurah Rai airport is a national hub with many
transiting flights.
The airport's initial closure was for 24 hours until early Tuesday, but there could be prolonged or repeated disruptions
More than 400 flights to and from Bali were cancelled and nearly 60,000 travelers have been stranded
Thick clouds hide the volcanic ash billowing out of Mount Agung at Sanur Beach on the island
The
travel disruptions will ripple around the globe as the island is one of
Asia's top destinations, attracting five million visitors a year.
December through the first week of January is one of the island's busy
periods.
But the popular tourist areas
of Kuta and Seminyak and the airport are about 70 kilometers (43 miles)
from the volcano and largely safe even with a major eruption though
masks and goggles could prove necessary if there's significant ash
fall.
Activity at the mountain has
ramped up in recent weeks culminating with the cancellation of flights
in and out of Bali this week due to a large ash cloud thrown up by the
volcano.
Indonesia has raised its alert for Mt Agung to the highest level, warning of the risk of a lava eruption is 'imminent'.
Mount
Agung, which sits more than 3,000 metres high over eastern Bali, last
erupted in 1963 killing more than 1000 people and razing several
villages.
Authorities
have ordered up to 150,000 people to leave a danger zone that extends
10 kilometers from the crater in places and tourists shouldn't enter
it.
Up to 150,000 people have been
urged to evacuate areas within a 10 kilometre radius of Bali's Mt Agung
amid the issuing of its highest danger alert on Monday
The area, which includes a much-visited Hindu temple on the slopes of the volcano, will be prone to deadly mudflows and lava.
A
danger zone was expanded Monday morning amid issuing of the volcano's
highest alert, with heavy rain sending ash and magma towards nearby
villages.
As authorities attempt to
urge people to evacuate, only 40,000 have chosen to leave with many
'feeling safe' or staying to protect livestock, Bloomberg reports.
Some governments are advising citizens to defer travel to the island.
Malaysia's
foreign ministry said all but non-urgent travel should be delayed while
Australia, a big source of tourists for Bali, said people should be
aware that ash clouds could also close other airports in Indonesia
depending on weather conditions.

Maureen
Steele and Jackie Calabretta were scheduled to fly on a Garuda
Indonesia flight from Sydney via Bali to Jakarta on Monday for an
orangutan tour.
They were up at 4am to travel from Gosford and Wollongong to make the 10am flight which cost $700 return.
'We
were on the plane, all strapped in ready for departure, when the cabin
crew announced they needed to wait 10 minutes to get clearance,' Ms
Steele said at Sydney Airport.
'They told us they didn't get clearance so we all had to get off again.'
As
they passed back through customs, Ms Calabretta contacted Malaysia
Airlines and booked a new flight costing $600 one-way to Jakarta via
Kuala Lumpur.
'We have to go - we've
paid hundreds of dollars on the vaccinations and there have been lots of
preparations,' Ms Steele said as they settled in for a 10-hour wait.

A group of eight surfers are hoping they'll be able to fly to Bali on Tuesday.
James Hall, 18, said the Sydney friends had been planning their Sumatra surf trip for more than a year.
'It's
frustrating, we've been told we might be able to fly tomorrow, so we
just have to wait it out,' Mr Hall told AAP at Sydney's international
terminal.
'There's not much we can do - it's a volcano.'
The latest data from Agoda shows Bali is the number one destination for Australians travelling in December.
University
of Adelaide geologist Mark Tingay says the eruptions from Mount Agung
have sent plumes of ash 3000 metres into the air.
'The
volcanic eruption has moved on to the next, more severe, magmatic
eruption phase, where highly viscous lava can trap gasses under
pressure, potentially leading to an explosion,' he said in a statement.

Indonesia's
Volcano Observatory Notice for Aviation raised its aviation colour code
from orange to red, indicating a further eruption with significant
emission of volcanic ash into the atmosphere was imminent.
Australia's
Bureau of Meteorology's Volanic Ash Advisory Centre in Darwin issued
maps showing an ash cloud heading southeast over the neighbouring island
of Lombok away from Bali's capital Denpasar, where the international
airport is located.

cloud are highly unpredictable which means we may need to cancel
flights at short notice,' Jetstar warned on its website (stick image)
