DENPASAR, BALI — July 7, 2025 — A powerful eruption from Mount Lewotobi Laki-Laki in Indonesia’s East Nusa Tenggara has caused widespread air travel disruptions between Bali and Australia, affecting thousands of tourists amid the peak summer season. With a towering ash plume reaching 18 kilometers into the atmosphere, the eruption has forced airlines to cancel or delay flights and triggered travel chaos across key routes from Perth, Sydney, Melbourne, and other cities.
The eruption began around 1:00 PM AEST on July 7, prompting Indonesia’s MAGMA agency to issue a red aviation alert. The ash cloud, considered hazardous to aircraft, has forced the closure of multiple flight corridors over the Indonesian archipelago, with Bali’s Ngurah Rai International Airport (DPS) facing significant operational challenges.
Airlines Affected: Massive Flight Disruptions
Airlines across the Asia-Pacific region have been impacted by the volcanic activity, with carriers from Australia, India, New Zealand, and Singapore forced to cancel or reschedule flights bound for Bali.
Virgin Australia
- Status: Monitoring the situation; some Bali-bound flights under review.
- Advisory: Passengers urged to check flight status and anticipate possible delays.
Qantas Airways
- Delayed Flights:
- QF43 (Sydney to Denpasar)
- QF45 (Melbourne to Denpasar)
Both flights were delayed by at least four hours, with further postponements possible.
- Future Disruptions: The airline’s meteorological team continues to track ash cloud movement. Passengers should monitor updates through the Qantas app or website.
Jetstar Airways
- Cancelled Flights:
- JQ106 and JQ116 (Perth to Denpasar)
Afternoon services were cancelled due to hazardous flight conditions over Bali airspace.
- JQ106 and JQ116 (Perth to Denpasar)
- Impact: Perth, a primary hub for Bali-bound leisure travel, has experienced significant passenger disruption.
Other Airlines
- Singapore Airlines: Cancelled four flights between Singapore and Bali.
- Air India: Cancelled all India–Bali flights until further notice.
- Air New Zealand: Flights between Auckland and Denpasar suspended.
These cancellations reflect the eruption’s global ripple effect, leaving thousands of tourists stranded in airports across the Asia-Pacific.
Bali: The Epicentre of Tourism Disruption
Bali remains the most affected destination, with the volcanic ash cloud severely limiting takeoffs and landings at Denpasar Airport. The island, a top international travel destination especially for Australians, has seen its tourism flow grind to a halt, just as school holiday travel peaks.
Tour operators, resorts, and transportation services have been overwhelmed with change requests, rebookings, and stranded guests seeking alternate arrangements.
Australian Cities Impacted
Perth
Jetstar’s Perth–Bali routes were among the first to be grounded, cutting off a major Australian gateway to Indonesia. Travelers now face rescheduling uncertainties amid limited flight availability.
Sydney
Qantas passengers departing from Sydney Kingsford Smith Airport experienced extensive delays, with holding patterns and runway congestion worsening the disruption.
Melbourne
Similar delays hit Melbourne Tullamarine, where passengers on delayed QF45 reported hours-long waits. Travel agents in Victoria are now fielding urgent itinerary adjustments.
Volcanic Ash Safety Concerns
Volcanic ash poses a serious aviation safety risk, capable of:
- Damaging jet engines
- Reducing visibility for pilots
- Compromising air traffic communication systems
The ash cloud from Mount Lewotobi Laki-Laki, reaching the stratosphere, has been designated hazardous by Indonesia’s MAGMA Agency, which also warned of lahar flows—mudslides of volcanic debris—that could affect surrounding communities if heavy rainfall continues.
Travel Advisory and Health Alerts
Both the Indonesian Government and Australia’s Smartraveller website have issued updated travel advisories, warning citizens to:
- Avoid non-essential travel to affected regions
- Wear masks to protect against ash inhalation
- Follow airline instructions for rebooking and refunds
Volcanic ash can irritate eyes, skin, and lungs, particularly among people with pre-existing respiratory conditions. Travelers in Bali are advised to remain indoors during periods of heavy ashfall.
Government Response and Recovery Planning
Indonesian authorities have placed emergency teams on standby in Bali and East Nusa Tenggara, coordinating efforts with local airports, airlines, and disaster response agencies. Flight safety remains the top priority, and military aircraft may be deployed to assist in emergency evacuations if conditions worsen.
Australia’s Department of Foreign Affairs and Trade (DFAT) is also monitoring the situation and providing assistance to stranded Australian nationals through consular services in Denpasar and Jakarta.
What Travelers Should Do
- Check Airline Websites: Monitor real-time flight updates on the airline’s official platforms.
- Contact Your Airline: If your flight is cancelled, seek rebooking options or refund instructions directly.
- Consider Travel Insurance: If not already covered, purchase or review insurance plans for natural disaster-related cancellations.
- Limit Exposure: If in Bali, wear protective gear and avoid outdoor activities during ashfall.
- Stay Informed: Use trusted government sources like MAGMA Indonesia or Smartraveller for latest alerts and emergency guidance.
Long-Term Outlook and Summer Travel Considerations
With volcanic activity expected to continue intermittently, airlines are reviewing weather and ash movement hourly. Further flight disruptions are likely in the coming days or weeks, particularly as winds shift and ash dispersal patterns evolve.
This eruption comes at a critical time for international travel between Australia and Indonesia, where Bali is seen as the ideal winter escape for Australians. The disruption will likely have economic ramifications for Bali’s tourism industry, which heavily depends on Australian visitors.
Conclusion: Safety, Flexibility, and Preparedness
The eruption of Mount Lewotobi Laki-Laki underscores the importance of preparedness in global travel, particularly during high-risk seasons. Travelers to Bali from Australia and beyond must remain flexible and vigilant as airlines like Qantas, Jetstar, Virgin Australia, and others adapt to evolving safety conditions.
While travel plans may be disrupted, staying informed, prioritizing health, and remaining patient will help travelers navigate these unexpected volcanic challenges safely and responsibly.
