The most recent July 7, 2025, eruption of Mount Lewotobi Laki-Laki in Indonesia’s East Nusa Tenggara has seen enormous disruptions in air traffic, particularly between Bali and Australia. As one of the favorite Australian summer holiday destinations, the current volcanic eruption has seen mass flight cancellations, postponements, and enormous confusion for tens of thousands of travelers. This article provides you with in-depth insights into the involved flights, the in-disarray destinations, safety alerts, and traveler recommendations following the eruption.

On July 7, 2025, at around 1:00 PM AEST, Mount Lewotobi Laki-Laki erupted once again, sending an ash cloud up to 18 kilometers into the sky. The eruption has raised serious concerns about the safety of air travel in the region. Indonesia’s geological and volcanology agency (MAGMA) quickly issued an aviation red alert, warning of hazardous volcanic ash clouds that could affect flight operations and pose a risk to both aircraft and passengers.

The ash cloud has the potential to disrupt flight paths, as it can severely impact visibility and pose dangers to engines. The eruption is particularly significant due to the widespread impact on both domestic and international flights to Bali, a popular summer vacation spot for many Australians.

Several international airlines have also been impacted by the eruption:

Bali, known for its stunning beaches and rich cultural heritage, is the primary destination affected by the eruption. The ash cloud from Mount Lewotobi Laki-Laki has caused major disruptions in air travel, especially during the peak summer travel season. Bali is a favorite vacation spot for Australians, and these travel disruptions are significantly impacting the local tourism industry, with thousands of tourists left stranded or unable to travel.

Jetstar flights from Perth to Bali have been particularly impacted. Flights JQ106 and JQ116 were scheduled to depart in the afternoon but were cancelled as a result of the volcanic activity. With Perth being a key departure hub for travelers heading to Bali, these cancellations have caused additional inconvenience for those looking to spend their summer holidays in Indonesia.

Qantas flight QF43 from Sydney to Bali has been delayed due to the volcanic ash cloud. Sydney, one of the major international airports in Australia, has been one of the hardest-hit locations as a result of the disruptions, with passengers on Qantas flights facing extended waits at the airport.

Similar to Sydney, Qantas flight QF45 from Melbourne to Bali has been delayed. The delays are expected to last several hours, and further disruptions could occur depending on the continued eruption activity from Mount Lewotobi.

Volcanic ash clouds pose a significant risk to aviation, as they can damage aircraft engines, create hazardous flying conditions, and obscure visibility. The ash cloud from Mount Lewotobi Laki-Laki, which reached altitudes of up to 18 kilometers, has been declared hazardous for aviation, leading to the grounding of multiple flights.

The Indonesian government’s MAGMA agency has issued its highest-level emergency alert for areas near the volcano. Authorities are concerned about the possibility of lahar floods—mud or debris flows of volcanic materials—which could affect nearby communities, especially if heavy rainfall occurs. This adds to the already challenging conditions for travelers and local populations alike.

In response to the eruption, both Indonesian and Australian authorities have emphasized the importance of safety. The Australian Government’s Smartraveller website has issued travel advisories, urging travelers to exercise caution and to monitor updates closely. Passengers flying to and from Bali are advised to:

The disruptions caused by the eruption of Mount Lewotobi Laki-Laki are expected to continue for the coming days, potentially weeks, depending on the continued volcanic activity and the movement of the ash cloud. Airlines have stated that they are working closely with aviation authorities to assess the situation in real-time and will make further decisions regarding flight safety and schedules as more information becomes available.

As we enter the peak summer travel season, it’s essential to be prepared for unexpected disruptions like volcanic eruptions. Bali has long been a top destination for Australians looking to escape the winter months, with its tropical climate and beautiful beaches. However, incidents like the Mount Lewotobi Laki-Laki eruption highlight the importance of flexibility and preparation when traveling abroad.

Given the uncertainty surrounding volcanic activity and its potential to disrupt flights, travelers are advised to plan ahead, especially if their trip to Bali is imminent. Whether you’re rescheduling flights, considering alternative travel dates, or rethinking your summer vacation entirely, staying informed is key to navigating these disruptions smoothly.

Mount Lewotobi Laki-Laki’s eruption has been very disruptive for commuters between Bali and Australia. Airlines like Virgin Australia, Qantas, and Jetstar had flights either canceled or delayed due to the volcano’s ash cloud. While airlines are intensely reviewing the issue, tourists are advised to stay informed, frequently check their flight status, and be cautious.

With the rising number of trips during summer, preparation for emergencies becomes paramount. Having travel insurance, studying safety procedures in place, and adaptability in your traveling dates will take you through disruptions and ensure you stay safe during traveling.
