During 2027, Papua New Guinea’s Kokoda trek may experience record water shortages during the country’s worst El Niño on record. Australian authorities say the dry season will worsen in early 2027. That will further increase the risk of food and water shortages and reduce hydropower throughout the country. The dry season poses reduced risks for trekkers since river crossings and path traversing become easier during the dry season. However, water may become inadequate for drinking, and trekking and support services in Port Moresby may also become insufficient. Thus, Kokoda water insecurity is becoming a priority for trek operators and for all communities involved during the Kokoda trek.
The dry season normally gives travellers their best chance to complete the Kokoda Track. Lower rainfall can mean firmer ground, more manageable river crossings and fewer delays caused by deep mud.

A significant El Niño could change that balance in 2027. The weather may make parts of the track less muddy while creating a different danger through falling water availability.
Australia updated its official Papua New Guinea travel advisory on 20 August 2026. It said several provinces were experiencing worsening drought linked to a significant El Niño event.

The advisory expects conditions to intensify into early 2027. It warns of consequences for food and water security among local communities.
That forecast does not prove that the Kokoda Track will close. It does, however, create an urgent planning issue for travellers, camps, licensed operators, guides and porters.
Kokoda trekking water security could become as important as physical fitness, permits and weatherproof equipment. Visitors may need to ask much more detailed questions about drinking water before paying for a 2027 expedition.
Papua New Guinea’s official tourism guidance identifies the drier months as the most suitable period for crossing Kokoda. The preferred season generally runs from May to October, although organised journeys are also popular around Anzac Day in April.
Rainfall is normally lower during these months. Rivers can be easier to cross and track conditions can become more predictable.
The wet season presents the opposite difficulties. Heavy rain can turn steep descents into slippery slopes, swell rivers and delay movement through isolated sections.
The emerging concern is that an unusually intense dry spell may move the risk in another direction. Easier paths will offer little comfort if natural water sources, village tanks or campsite supplies fall below normal levels.
This is the central contradiction facing the 2027 season. The weather window promoted as the safer period for walking could produce the greatest logistical test for water provision.
The Kokoda Track crosses Papua New Guinea’s Owen Stanley Range, connecting Owers’ Corner in Central Province with the Kokoda area in Oro Province. The recognised historic route extends for about 96 kilometres, although distances described by operators can vary according to the itinerary and connecting sections used.
Most organised expeditions take between six and twelve days. Many travellers walk for six to ten hours on steep, humid and isolated terrain each day.
The track reaches approximately 2,190 metres near Mount Bellamy. Its narrow ridges, sharp climbs, tropical heat and difficult descents demand serious preparation.
There is no continuous road running beside the route. Medical evacuation, resupply and communication can therefore be far more complicated than on an urban walking holiday.
Visitors generally travel with licensed operators. Guides and porters support navigation, camp arrangements, food, equipment and emergency responses.
All these services depend on reliable local supplies. Water supports drinking, cooking, cleaning, sanitation and basic health care across the journey.
Kokoda is both an adventure route and a place of remembrance. It follows the landscape associated with the 1942 Kokoda Campaign, when Australian and Papua New Guinean forces and carriers confronted the Japanese advance towards Port Moresby.
The track now attracts travellers seeking military history, personal challenge and contact with local communities. Australian visitors form a particularly important market because of the route’s connection with wartime memory.
Sites such as Isurava hold deep emotional importance. Organised groups frequently combine trekking with historical briefings, memorial services and visits to former battle locations.
This distinguishes Kokoda from a conventional hiking product. Travellers often spend months training and may regard completing the route as a once-in-a-lifetime commitment.
The emotional value also influences booking behaviour. People may accept difficult conditions, but they still need accurate information about water, health, access and emergency planning.
A low river can be easier to cross. That does not automatically mean it provides clean or dependable drinking water.
Reduced flow may concentrate sediment and contamination. Smaller pools may also face greater pressure from people, animals and nearby settlements.
Water quality can change from one section of the track to another. A source available to one group may be insufficient when several trekking parties arrive close together.
Tour operators may need to review how frequently they refill supplies. They may also need purification equipment, backup containers and contingency plans for unexpectedly dry camps.
Trekkers should never assume clear water is safe. Treatment methods, equipment standards and operator protocols must be confirmed before departure.
The issue is especially important because dehydration can develop quickly during long climbs. Heat, humidity, heavy packs and repeated physical effort increase the body’s need for fluids.
The Australian advisory provides a broad national warning. It does not offer a day-by-day forecast for each Kokoda campsite or confirm that the track will become impassable.
It also does not state that drought has caused a Kokoda closure. Any article making that claim would go beyond the evidence currently available.
The advisory separately warns that local communities can block the track at short notice. Travellers are told to consult their trekking company for current information.
These are two distinct developments. One concerns a worsening climate and utility emergency, while the other concerns uncertain community access.
They could still interact. Food or water stress may increase pressure on communities, but no official source presently confirms that drought will cause a blockade.
Responsible coverage must preserve that distinction. The valid story is about rising operational risk and the need for better preparation, not a confirmed closure.
| Development | Official position | Possible tourism relevance |
|---|---|---|
| Significant El Niño | Drought is worsening across several PNG provinces | More pressure on natural and stored water |
| Early 2027 outlook | Conditions may intensify into early 2027 | Greater uncertainty during advance bookings |
| Food and water security | Local populations may face increasing pressure | Visitor demand could compete with community needs |
| Hydropower capacity | Drought is affecting electricity generation | Hotels and visitor services may face disruption |
| Port Moresby load shedding | Electricity cuts are already in place | Gateway stays and tour preparations may become harder |
| Essential utilities | Water and power interruptions remain possible | Accommodation needs reliable backup systems |
| Kokoda community access | Local communities can block the track at short notice | Operators must confirm access before departure |
| Public health | Polio, measles and rubella cases have been reported | Vaccination and medical preparation remain essential |
The table separates confirmed official information from its possible tourism consequences. Those consequences require monitoring rather than presenting them as inevitable outcomes.
Most international Kokoda itineraries begin or end in Port Moresby. Travellers may spend one or more nights there while meeting their group, checking equipment and preparing for transport towards the track.
The drought is already affecting hydropower generation. Load shedding is taking place across the capital, according to the Australian advisory.
Water infrastructure has also faced pressure. Water PNG completed significant repairs to a major pipeline supplying Port Moresby in mid-August 2026.
An extended water or electricity interruption could affect hotels, restaurants, communications and retail services. Smaller tourism businesses may have less backup capacity than major properties.
Power cuts can interrupt card payments, internet services and refrigeration. Water interruptions can affect bathrooms, kitchens, laundry and cleaning.
These problems do not mean tourism services have stopped. They show why hotels and operators need tested backup arrangements before the 2027 trekking market expands.
No official source cited here has announced an El Niño-related suspension of international or domestic flights. Travellers should therefore avoid assuming that the drought has closed airports or cancelled air services.
The aviation impact is more indirect. Kokoda itineraries depend on flights into Port Moresby and, for some journeys, small-aircraft access near the northern end of the route.
Passengers may arrive with tightly organised schedules. A disruption involving electricity, communications, road transfers or local access can weaken the complete itinerary even when the flight operates normally.
Airlines may also receive more questions about ticket flexibility. Trekkers committing months in advance could seek fares that permit changes if official conditions deteriorate.
Travel agents should keep air travel and track access under separate checks. A confirmed flight does not guarantee that every land component will operate unchanged.
Hotels form a critical buffer between international transport and remote trekking. They provide secure accommodation, drinking water, meals, charging facilities and final equipment checks.
Properties serving trekking groups should be able to explain their backup arrangements clearly. These may include generators, stored potable water, emergency lighting and alternative communications.
Visitors should ask whether essential services can continue during load shedding. They should also confirm whether bottled or treated water remains available when municipal supplies are interrupted.
Operators may need additional time between arrival and departure. A longer buffer could help groups manage delayed luggage, utility problems or last-minute changes.
There is also a cost issue. Diesel generation, water storage and emergency supplies can raise operating expenses, especially for smaller businesses.
The official Papua New Guinea Kokoda preparation guidance stresses hydration, fitness, first aid, insurance and suitable equipment. El Niño makes each requirement more important.
Operators may need to reassess water points before every departure. Conditions recorded during an earlier trek may not remain reliable weeks later.
Group size could matter. Larger parties place more pressure on limited supplies and require greater storage capacity at camps.
Routes, rest stops and overnight locations may require adjustment where safe water cannot be guaranteed. Such changes should be communicated before departure whenever possible.
Emergency planning must also cover heat illness, dehydration and gastrointestinal infection. Guides should know when a traveller needs rest, treatment or evacuation.
Contracts deserve attention as well. Travellers should understand what happens if an operator changes the itinerary, delays departure or cannot use a planned campsite.
The Kokoda Track passes through customary land and living communities. These settlements are not scenery placed around a tourism product.
Residents provide guiding, carrying, accommodation, food, maintenance and cultural knowledge. Tourism income can support households and small businesses in places with limited conventional employment.
Drought changes the ethical balance. A trekking group should not consume water that a village needs for drinking, cooking or children.
Operators will need close consultation with landowners and community leaders. Local information may be more useful than a general seasonal assumption made months earlier.
Fair payment also matters. If communities must store more water, transport food or provide additional services, their costs may rise.
Protecting the trekking market therefore requires protecting local living conditions. A route cannot remain sustainable if visitors receive secure supplies while host settlements carry the shortage.
Papua New Guinea’s visitor economy has been rebuilding. The Tourism Promotion Authority’s 2025 International Visitor Survey recorded 103,881 international arrivals in 2025, compared with 100,223 in 2024.
That represents an increase of approximately 3.6 per cent. The survey analysed 4,827 valid responses from 5,139 collected questionnaires.
It also found that 41 per cent of respondents were first-time visitors. Their reported average household income sat between US$80,000 and US$99,999.
These figures show a recovering market with valuable international demand. They also demonstrate why traveller confidence matters.
The official 2025 data did not publish a separate employment total for Kokoda tourism. It would therefore be unsafe to claim a precise number of jobs supported by the track.
The economic chain is nevertheless clear. Spending reaches operators, accommodation businesses, transport providers, guides, porters, food suppliers and communities.
A disrupted season could spread beyond trekking companies. It could affect households and small enterprises that earn money from each visiting group.
Australia has historically been Papua New Guinea’s leading visitor source. Its proximity, air connections and Kokoda’s wartime significance make it central to the trekking market.
This gives the Australian travel advisory considerable influence. Tourists, schools, clubs, insurers and organised groups may use it when assessing whether to proceed.
The advisory still recommends exercising a high degree of caution in Papua New Guinea overall. Higher warning levels apply to several regions outside the main Kokoda tourism discussion.
It also highlights serious crime, civil unrest, tribal violence and possible interruptions to transport and essential services. Trekkers must consider these risks alongside drought.
The article’s climate focus should not obscure the wider advisory. Water is an emerging pressure within an already complex operating environment.
Papua New Guinea’s tropical conditions already make dehydration and illness important trekking risks. Reduced water availability could make hygiene and safe food preparation harder.
The travel advisory also reports vaccine-derived polio, measles and rubella cases. Visitors should seek medical advice and confirm that routine and destination-specific vaccinations are current.
A medical assessment is particularly important for older travellers and people with heart, kidney or heat-related conditions. Kokoda demands sustained physical effort far from major hospitals.
Insurance should explicitly cover trekking at the planned altitude. It should also include emergency evacuation and disruption where available.
Travellers should carry personal medication in sufficient quantities. They should not rely on finding specialised supplies along the track.
Papua New Guinea has continued destination marketing, visitor research and industry development through its Tourism Promotion Authority. Its campaigns highlight culture, diving, trekking, wartime history and community experiences.
The authority also promotes licensed Kokoda operators and permits. These controls support route management and encourage structured travel.
The next requirement is climate-ready tourism communication. Seasonal descriptions based only on “wet” and “dry” conditions may no longer be enough during a strong El Niño.
Government agencies could improve confidence by publishing track-specific water updates. Operators would benefit from consistent information on communities, camps, rivers and access points.
The country’s tourism recovery does not depend only on attracting more visitors. It depends on showing that remote experiences can operate responsibly during changing climate conditions.
No new visa reform in the official material reviewed for this report changes the central drought issue. Travellers must still check Papua New Guinea’s current entry requirements before booking.
A valid visa or entry permission does not guarantee access to the Kokoda Track. Permits, licensed operator arrangements, local conditions and community access remain separate requirements.
Visitors should also check passport validity, vaccination guidance and insurance terms. These practical steps should be completed well before departure.
Travel documentation is only one part of readiness. In 2027, water planning may become the decisive operational question.
Travellers considering Kokoda in 2027 should request written answers from their operator. General promises about “plenty of water” are not enough during a developing drought.
Important questions include:
These questions do not suggest that visitors should cancel automatically. They allow travellers to compare operators on safety, transparency and community responsibility.
The official outlook extends into early 2027. It does not establish conditions for the entire May-to-October trekking season.
Rainfall patterns, water storage and local conditions may change. Authorities could revise their advice as new climate information becomes available.
Travellers should therefore avoid treating a booking made in 2026 as a fixed guarantee. Regular checks are essential before final payment, departure and entry onto the track.
Operators should provide evidence-based updates rather than broad reassurance. Clear information can protect bookings more effectively than silence.
The strongest outcome would be a season supported by reliable monitoring, community consultation and flexible operations. That approach would preserve access without placing unacceptable pressure on local water supplies.
No official source cited in this report confirms a drought-related closure. Australia warns that communities can block the track at short notice, but it does not say El Niño has caused such a blockade. Travellers should confirm current access directly with a licensed operator.
May to October is normally considered the drier and more predictable trekking period. However, the current El Niño outlook means visitors should check water availability, local access and official advice before choosing exact dates.
Travellers should use an operator with a documented water and purification plan. They should confirm refill points, emergency reserves and treatment methods, while carrying personal hydration equipment recommended by the operator.
Although it has not been confirmed, 2027’s Kokoda trail will most likely not go ahead as planned. Dry season treks usually begin in the fall. However, this year’s El Niño weather phenomenon is already causing drought. That completely depletes the country’s hydropower supply and severely affects water security. Camp trekking support personnel and remote camps are already feeling the strain. Trekking operators must continue to monitor the available water supply and protect the village reserve to ensure the villagers’ supply of water. Trekkers are advised to ensure that they have all necessary permits as well as health and insurance preparation. It is safe to say that with such a volatile climate, the trek to pay homage to the soldiers should not be prioritized. Water security is the 2027 season’s greatest challenge.
