ASIO's 2026 Threat Assessment: Why Threat-Informed Security Has Never Been More Important

Protecting What Matters. Preparing For What's Next.

In June 2026, ASIO Director-General Mike Burgess delivered the Annual Threat Assessment, describing Australia's security environment as increasingly dynamic, diverse and degraded. The assessment highlighted the interconnected nature of modern threats, including espionage, foreign interference, terrorism, sabotage and politically motivated violence.

For security professionals, these findings reinforce a reality that many organisations are already experiencing: the threat environment is becoming increasingly complex, and traditional approaches to security are no longer sufficient.

The question facing organisations is no longer whether threats exist.

The question is whether organisations truly understand which threats matter most to them.

Understanding the Threat Before Managing the Risk

Many organisations invest considerable time and resources into security controls, compliance obligations and risk registers. While these activities remain important, they often begin with a critical assumption:

That the organisation already understands its threat environment.

In reality, security risks cannot exist without a threat.

Threats drive risk.

Understanding who may seek to target an organisation, why they may act and what capabilities they possess is fundamental to effective protective security decision-making.

This principle sits at the heart of the Montane methodology:

UNDERSTAND THE THREAT.

MANAGE THE RISK.

BUILD RESILIENCE.

What ASIO Is Telling Us

The most significant theme emerging from the 2026 Threat Assessment is not the presence of any single threat.

It is the convergence of multiple threats operating simultaneously. ASIO identified concerns relating to terrorism, foreign interference, espionage and sabotage, noting that these threats are increasingly interconnected and collectively degrading Australia's security environment.

The assessment also highlights the growing role of online radicalisation, lone actors, foreign intelligence activities and efforts to target Australian institutions, critical infrastructure and defence-related initiatives.

For organisations, this means that security planning can no longer focus on a single threat stream.

Security programs must account for multiple actor groups operating with different motivations, capabilities and objectives.

The Montane Threat Actor Framework

To support threat-informed decision-making, Montane categorises threats into four broad actor groups:

Strategic Threat Actors

Strategic Threat Actors possess high capability and intent and seek to advance political, economic, criminal or strategic objectives.

Examples include:

• Serious and Organised Crime

  
  

• Foreign Intelligence Entities and Their Proxies

  
  

ASIO's continued emphasis on espionage and foreign interference reinforces the importance of understanding strategic actors and the long-term risks they present to organisations.

Motivated Threat Actors

Motivated Threat Actors are driven primarily by ideology, beliefs, grievance, influence or trusted access.

Examples include:

• Issue Motivated Groups

  
  

• Trusted Insiders

  
  

These actors may not possess the sophisticated resources of foreign intelligence services or organised crime groups, but they can still create significant operational and reputational impacts.

Criminal Opportunity Threat Actors

Criminal Opportunity Threat Actors seek financial gain or exploit vulnerabilities when opportunities arise.

Examples include:

• Cyber Enabled Crime

  
  

• Petty Crime

  
  

These actors remain among the most common threats affecting organisations and continue to exploit weaknesses in information systems, physical security arrangements and business processes.

Apex Threat Actors

Apex Threat Actors represent the highest-consequence threat category.

Examples include:

• Serious and Violent Crime

  
  

• Terrorism and Violent Extremism

  
  

ASIO's assessment highlighted continued concerns regarding violent extremism and changing patterns of radicalisation, particularly where actors may mobilise rapidly and with limited warning.

While incidents involving Apex Threat Actors may be less frequent, their potential impacts are often severe and far-reaching.

What This Means for Organisations

The implications for organisations are clear.

Security programs should not be built solely around compliance obligations or generic threat assumptions.

Instead, organisations should seek to understand:

• Which threat actors are most relevant to their operating environment

  
  

• Why these actors may target them

  
  

• What capabilities those actors possess

  
  

• Which assets are likely to attract attention

  
  

• Whether current controls are proportionate to credible threats

  
  

A threat-informed approach allows organisations to focus finite resources where they can achieve the greatest reduction in risk.

Building Resilience in a Complex Threat Environment

One of the most important messages in the 2026 ASIO Threat Assessment is that security challenges are becoming more interconnected and more difficult to separate into traditional categories.

As threats evolve, organisations must adapt.

Protective security is no longer simply about physical barriers, cyber controls or personnel checks. Effective security requires a holistic approach that integrates threat understanding, risk management and organisational resilience.

Those organisations that understand their threat landscape will be better positioned to make informed decisions, allocate resources effectively and respond confidently when incidents occur.

Final Thoughts

ASIO's 2026 Threat Assessment serves as a timely reminder that Australia's security environment continues to evolve.

For organisations, the most important lesson is not simply understanding that threats exist.

It is understanding which threats matter most, why they matter, and what can be done about them.

Because effective security begins with understanding the threat.
