Since that date there has been fluctuating seismic activity and smoke spewing from the top of the ancient volcano.
Officials in Bali are working to assure tourists that most of the island is still safe for holidays, amid a severe decline in bookings due to the warning.
According to local tourism authorities, only two per cent of the island would be affected if Mount Agung were to erupt.
Bali Tourism Hospitality spokesman Dewa Gede Ngurah Byomantara said: “The volcanic activity at Mount Agung should not affect other tourist spots.”
Some airlines have offered customers refunds if they choose to cancel their holidays to the area.
Other airlines have been carrying extra fuel in case they need to turn around or divert.
Officials in Indonesia have drawn up plans to divert planes to 10 airports throughout the country in the event of an eruption.
Uncertainty surrounding the possible eruption of Mount Agung could see Bali’s tourism industry plummet by 30 per cent, according to officials.
