From Warning Signs to Preparedness: How PNG Should Respond to the West Papua Security Challenge

By Bernard Yegiora

The first two articles in this series argued that developments across PNG’s western border should no longer be viewed simply as an Indonesian domestic issue. The first identified warning signs emerging from the West Papua conflict, while the second considered what happens when a neighbouring conflict begins to enter PNG’s security space.

This final article asks the more important policy question: What should PNG do about it?

The answer is not that PNG should take sides in the West Papua conflict. Nor should PNG abandon its established diplomatic relationship with Indonesia. Rather, PNG needs to recognise that a prolonged conflict immediately across its land border creates national security risks that require sustained monitoring, intelligence assessment, inter-agency coordination and contingency planning.

The central issue is preparedness.

A Changing Security Environment

PNG has lived alongside the West Papua conflict for decades. The border has experienced refugee movements, illegal crossings and periodic security incidents. What requires attention today, however, is the changing character of the conflict and the narratives surrounding it.

Recent developments associated with armed separatist groups—including the visibility of firearms in publicly circulated material, attacks and killings, and increasingly assertive political messaging—should be assessed carefully by PNG's security agencies.

Particularly concerning is rhetoric that places PNG and Bougainville within the wider West Papuan political narrative.

West Papuan independence supporters have historically expressed solidarity with other Melanesian independence movements. Support for Bougainville's independence aspirations therefore has implications for PNG. More recent rhetoric referring to PNG's role within Melanesia and suggesting that PNG could assist West Papua should also attract the attention of national security analysts.

These statements do not establish that armed groups intend to target PNG. They should not be interpreted that way without evidence. But intelligence work is not simply about responding after an intention becomes an action. It involves identifying indicators, assessing intentions and capabilities, analysing possible scenarios and providing government with sufficient warning to make informed decisions.

PNG Is No Longer Merely an Observer

Geography makes PNG different from other Pacific Island countries discussing West Papua.

PNG shares a long and difficult-to-police land border with Indonesia. Communities, kinship networks and traditional movements predate the international boundary. Developments on one side of the border can therefore have consequences on the other.

This creates several possible security challenges: unauthorised border crossings, refugee movements, weapons trafficking, transnational criminal activity, armed actors entering PNG territory, misinformation and political mobilisation, and diplomatic incidents involving Indonesian security forces operating close to the border.

PNG must consequently distinguish between its diplomatic position on West Papua and its national security responsibilities along the border.

Port Moresby may continue to recognise Indonesian sovereignty while simultaneously strengthening its capacity to monitor developments in the border region. There is no contradiction between the two positions. It is what a responsible state should do.

The NSA Should Lead Strategic Assessment

The establishment of the National Security Agency provides PNG with an opportunity to strengthen strategic assessment of emerging national security threats.

West Papua should be treated as a standing national security issue requiring continuous assessment rather than something examined only when an incident occurs.

The NSA should develop a dedicated analytical capability covering the PNG–Indonesia border and the West Papua conflict. This should bring together information from the PNG Defence Force, Royal PNG Constabulary, immigration authorities, Customs, Foreign Affairs, provincial administrations and other relevant agencies.

The objective should not simply be collecting information. The more important task is fusion and assessment.

Different agencies may possess individual pieces of information that appear insignificant in isolation. When combined, however, they may reveal changes in armed-group activity, population movements, weapons flows, political mobilisation or other indicators of escalation.

Regular strategic assessments should therefore be provided to the National Security Council and relevant ministers.

Strengthen Intelligence Along the Border

PNG also needs stronger situational awareness along its western frontier.

The physical characteristics of the border make complete surveillance unrealistic. Dense forests, mountains, rivers and isolated communities make conventional border policing extremely difficult.

That means human intelligence remains important.

Border communities should not merely be viewed as populations to be monitored. They can be important partners in national security. Local knowledge can provide early warning of unusual movements, unfamiliar armed individuals, changes in cross-border activity and emerging tensions.

PNG's security agencies therefore need relationships of trust with communities along the border.

Technology should complement this human network. Communications systems, surveillance capabilities, mapping, satellite imagery where available, and improved information-sharing between agencies can strengthen the government's understanding of what is occurring in remote areas.

Weapons Require Particular Attention

One development deserving careful monitoring is the visibility of increasingly sophisticated firearms in material circulated by armed groups.

PNG authorities should avoid drawing conclusions about the source of individual weapons without verified evidence. Nevertheless, the presence and movement of firearms in a conflict zone adjacent to PNG creates an obvious security concern.

The question for PNG is straightforward: Could weapons, ammunition or associated networks eventually move across the border?

PNG already faces serious domestic challenges involving illegal firearms. Any additional transnational source of weapons would compound an existing national security problem.

Weapons monitoring should therefore form part of a broader border intelligence strategy involving Customs, police, defence and intelligence agencies.

Bougainville Adds Another Dimension

Bougainville makes the issue more complicated.

West Papuan expressions of solidarity with Bougainville's independence aspirations should not automatically be interpreted as interference. Political movements frequently express solidarity with one another.

Nevertheless, PNG's security establishment should monitor attempts by external political or armed movements to connect their struggles with domestic political issues in PNG.

Bougainville's political future is an internal constitutional and political matter between the Government of PNG and the Autonomous Bougainville Government.

PNG should therefore remain alert to narratives that attempt to internationalize or link the Bougainville process with unrelated separatist conflicts elsewhere.

Again, monitoring does not mean suppressing legitimate political debate. It means understanding the strategic environment in which that debate occurs.

PNG's Growing Melanesian Responsibility

There is also a broader regional dimension.

PNG is increasingly expected to exercise leadership in Melanesia. Its population, economy, geographic size and diplomatic weight give it a position unlike that of smaller Pacific Island states.

That position brings responsibilities.

West Papua is politically sensitive across Melanesia. Public sympathy for West Papuans exists in several countries and among civil society organisations. Indonesia, meanwhile, is an important neighbour and bilateral partner of PNG.

PNG therefore occupies a difficult strategic position.

The country must protect its relationship with Indonesia, maintain border stability, respect humanitarian considerations, manage domestic opinion and engage its Melanesian partners.

This requires disciplined diplomacy rather than emotional foreign policy.

PNG should continue direct communication with Jakarta while ensuring that its own national interests remain paramount. Border cooperation should be strengthened, but PNG must retain independent situational awareness and analytical capacity. A state should never depend entirely on another country to explain security developments occurring immediately across its own border.

Build Scenarios Before a Crisis Occurs

Perhaps the most important requirement is contingency planning.

PNG should ask difficult questions now rather than during a crisis.

• What happens if fighting intensifies close to the PNG border?
• What happens if hundreds or thousands of people cross into PNG?
• What happens if armed combatants enter PNG territory?
• What happens if weapons move across the border?
• What happens if an Indonesian security operation unintentionally crosses into PNG territory?
• What happens if West Papua-related political mobilization increases inside PNG?
• What happens if the conflict becomes connected rhetorically or organizationally with political movements elsewhere in Melanesia?

These are scenarios, not predictions.

But national security planning exists precisely because governments cannot wait until a worst-case scenario materialises before deciding how to respond.

The NSA, PNG Defence Force, police, Foreign Affairs, immigration authorities, provincial governments and humanitarian agencies should conduct scenario-based exercises covering possible escalation along the western border.

Clear chains of responsibility should be established before an emergency occurs.

From Reaction to Preparedness

PNG's traditional approach to West Papua has understandably been dominated by diplomacy. Maintaining a constructive relationship with Indonesia remains important.

But diplomacy alone is insufficient for managing a conflict occurring directly across PNG's border.

PNG needs diplomatic engagement backed by intelligence capability, border security, strategic assessment and contingency planning.

The objective is not confrontation with Indonesia. Neither is it intervention in the West Papua conflict.

The objective is national preparedness.

The warning signs discussed throughout this three-part series do not mean that a major security crisis is inevitable. They mean that PNG should understand the possibility and prepare accordingly.

That distinction is important.

National security institutions are most valuable when they identify risks before those risks become emergencies. PNG now has an opportunity to strengthen that capability through the NSA and the wider national security sector.

West Papua may remain an Indonesian domestic political and security problem. But the consequences of instability along PNG's western frontier cannot automatically be regarded as Indonesia's problem alone.

For PNG, geography has already made West Papua a permanent national security consideration.

The strategic question is whether PNG prepares for that reality now—or waits until events force it to respond.
