Why Australia Is Tightening Asbestos Rules — And Which Properties Are Most at Risk

Australia's tightening approach to asbestos management is not happening in a vacuum.

It is a direct response to what is still being found on real sites: undocumented materials, incomplete asbestos registers and exposure risks that only become visible once work has already started.

While national policy is focused on improving long-term outcomes, the immediate reality is more direct: many properties already carry a higher asbestos risk profile than their documentation suggests.

This page explains why asbestos rules are tightening, which properties are most affected, and where risks are commonly missed in practice.

Why the rules are tightening

The national review and updated asbestos strategy are being driven by consistent issues observed across the industry.

Persistent presence of asbestos

Asbestos remains widespread across Australian buildings, particularly those constructed before 1990. Without proactive intervention, these materials will remain in place for decades.

Gaps between documentation and reality

In many cases, what is recorded in an asbestos register does not fully match what exists on site. This gap is often caused by:

• Limited or non-intrusive inspections
• Inaccessible areas that were not assessed
• Changes to buildings over time (fit-outs, refurbishments, services upgrades)

Increased exposure during works

Asbestos is most commonly discovered:

• During demolition
• During refurbishment
• When services are upgraded or modified

At that point, the issue is no longer theoretical — it becomes a cost, safety and compliance problem partway through a project.

Inconsistent compliance across properties

Some buildings are well managed with current registers and clear procedures. Others rely on outdated reports or assumptions, creating uneven risk across the built environment.

The shift in focus

The direction of change is clear:

• Less tolerance for unknowns in high-risk buildings
• Greater expectation that risks are identified before work starts
• Increased accountability for property owners and duty holders

Which properties are most at risk

While asbestos can be present in many environments, certain property types consistently present higher risk.

Pre-1990 buildings

Properties constructed before 1990 are significantly more likely to contain asbestos in:

• Wall and ceiling linings
• Eaves and external cladding
• Flooring and adhesives
• Insulation, gaskets and services

For these buildings, the question is rarely if asbestos is present, but where it is and in what condition.

Commercial and multi-tenancy sites

These sites often involve:

• Multiple renovations over time
• Inconsistent documentation from different contractors
• Shared responsibility across owners, managers and tenants

This increases the likelihood of:

• Missing or fragmented records
• Untracked changes to fabric and services
• Gaps in asbestos registers and management plans

Plant rooms, risers and service areas

Higher-risk zones include:

• Plant rooms
• Service risers
• Ceiling voids
• Subfloors and roof spaces

These areas are often:

• Difficult to access safely
• Poorly documented
• Excluded or deferred in non-intrusive inspections

Buildings with repeated refurbishment

Each refurbishment introduces risk if asbestos is not fully identified beforehand. Common issues include:

• Partial removal of materials
• New materials installed over older ACM
• Documentation not updated to reflect what was removed or remains

Properties with outdated asbestos registers

Registers that have not been reviewed for several years are a consistent risk indicator. They are often:

• Based on older inspection methods
• Missing updated site conditions and new works
• Not aligned with the current use of the building or tenancy layout

Where asbestos is commonly missed

Even where a register exists, there are predictable gaps.

Non-intrusive inspection limitations

Many inspections are conducted without disturbing building elements. This means materials behind:

• Walls
• Ceilings
• Floors

may not be identified without intrusive access.

Inaccessible areas

Areas not accessed at the time of inspection are often:

• Assumed to be low risk
• Noted as "no access"
• Left for future review

In practice, these areas frequently contain ACM that only becomes visible during works.

Service penetrations and concealed zones

Cut-throughs, pipework and concealed services often intersect with asbestos-containing materials that were not visible during the original inspection.

Assumptions based on previous reports

A common issue is reliance on older reports without:

• Verification
• Update
• Re-inspection

This creates a false sense of certainty that can be exposed quickly once works begin.

The real-world impact

When asbestos risk is not properly identified early, it typically emerges at the worst possible time.

During construction or demolition

• Work stops immediately
• Additional surveys are required at short notice
• Removal and delay costs increase

During maintenance or minor works

• Unexpected exposure risk is introduced
• Contractors may be placed at risk
• Compliance obligations are triggered mid-project

During due diligence or transactions

• Issues are raised by consultants
• Delays occur in settlement or financing
• Value, terms or scope are renegotiated

What this means for property owners and managers

The tightening of asbestos expectations changes how risk should be viewed. It is no longer just about having a document in place. It is about being able to demonstrate that:

• Risks are understood and prioritised
• Information is current and reflects how the site is used
• Unknowns have been addressed where reasonably practicable
