EPBC referrals. Why federal heritage assessment can cost $50,000 and 18 months.

The Environment Protection and Biodiversity Conservation Act 1999 is the federal layer above state and council planning. It applies to a relatively small number of properties but its assessment process is the longest and most expensive in the Australian planning system.

This post explains what triggers an EPBC referral, what the process costs, and how to know before you bid whether your purchase exposes you to it.

What EPBC does

The EPBC Act protects "matters of national environmental significance" (MNES). These include:

• World Heritage properties
• National Heritage places
• Commonwealth Heritage places
• Listed threatened species and ecological communities
• Migratory species protected under international agreements
• Ramsar wetlands
• Commonwealth marine areas

Any action that is likely to have a "significant impact" on a matter of national environmental significance must be referred to the Minister for the Environment. The referral process determines whether the action requires formal assessment, can proceed without assessment, or is refused.

When EPBC applies to property

For most Australian residential buyers, EPBC is not relevant. The matters of national environmental significance are concentrated in specific places and protected species. Three scenarios where it does apply:

Scenario 1: the property is on or near a National Heritage List place

The Sydney Opera House, the Great Barrier Reef, the Royal Exhibition Building in Melbourne, Port Arthur in Tasmania, the Murray-Darling Basin and around 120 other places are on the National Heritage List. Properties adjacent to these sites can trigger EPBC when development is proposed.

Scenario 2: the property contains habitat for listed threatened species

A 600 square metre suburban lot in inner Brisbane that happens to contain a flowering tree species used by a listed migratory bird may trigger EPBC during clearing.

The species do not always live full-time on the lot. The "habitat" definition is generous: if the lot provides occasional foraging, nesting, or roosting potential for a listed species, the EPBC trigger can apply.

Scenario 3: the property contains a listed ecological community

Listed ecological communities (e.g. White Box-Yellow Box-Blakely's Red Gum Grassy Woodland, Coastal Saltmarsh of Eastern Australia) span thousands of properties across Australia. Properties on or adjoining listed ecological communities can trigger EPBC during clearing or significant earthworks.

The referral process

When EPBC applies, the development process adds a federal layer on top of the normal state and council planning:

Step 1: self-assessment

The developer assesses whether the proposed action is likely to have a "significant impact" on the MNES. This requires an environmental consultant who specialises in EPBC matters. Cost: $4,000-12,000 for a substantial assessment.

If the self-assessment concludes no significant impact, the developer documents this and proceeds. The federal layer adds time and cost but no formal approval.

Step 2: referral

If the self-assessment concludes that significant impact is possible, the developer must refer the action to the federal environment department. The referral document includes:

• Description of the proposed action
• Description of the MNES affected
• Description of likely impacts
• Description of proposed mitigation

Cost: $5,000-15,000 for a substantial referral including supporting reports.

Step 3: ministerial decision

The Minister has 20 business days from referral to decide whether:

• The action is a controlled action requiring formal assessment
• The action is not a controlled action and can proceed
• The action is a controlled action but assessment is not required (rare)

Step 4: formal assessment

If the action is a controlled action, formal assessment follows. Options include:

• Assessment on referral information (fastest, lightest)
• Public Environment Report (moderate)
• Environmental Impact Statement (most thorough, typically required for major projects)
• Bilateral assessment using state-level EIS process

Cost: $20,000-200,000+ depending on assessment type and complexity. Timeline: 6-18 months.

Step 5: approval decision

The Minister decides whether to approve the action, approve with conditions, or refuse.

Total cost and timeline

For a substantial residential development that triggers EPBC, total federal layer cost is typically:

• Self-assessment: $4,000-12,000
• Referral: $5,000-15,000
• Formal assessment (if required): $20,000-80,000 for residential-scale projects
• Conditions implementation: $5,000-30,000

Total: $34,000-137,000 in additional cost beyond the standard DA.

Timeline addition: 6-18 months on top of the normal DA timeline.

When EPBC does NOT apply

The vast majority of Australian residential buyers will never deal with EPBC. The trigger requires:

• Significant impact (not minor or negligible impact)
• On a matter of national environmental significance (specific list, not all environments)
• That is likely (not merely possible)

For a standard 600 square metre suburban lot in an established residential area with no listed species, no listed ecological community, and no NHL/CHL proximity, EPBC is not relevant.

How to check before exchange

Two free sources:

1. EPBC Protected Matters Search

The federal environment department's Protected Matters Search Tool allows you to enter coordinates or upload a polygon and receive a report listing all the matters of national environmental significance within the search area.

Access: environment.gov.au/cgi-bin/sprat/public/protectedmatterssearchtool.pl. Free. Takes 60 seconds.

The report tells you whether any MNES are within or near the lot. If yes, EPBC is a potential consideration.

2. The relevant state biodiversity layer

NSW Biodiversity Values Map (covered separately), QLD Matters of State Environmental Significance, VIC Biodiversity Information System. State-level layers often overlap with EPBC triggers.

What to do if EPBC applies

If the search returns matters of national environmental significance:

1. Do not panic. Many properties are within EPBC mapping but the proposed development does not have significant impact.
2. Commission a pre-purchase EPBC scoping report. A specialist consultant can scope the likely federal-level cost and timeline for your intended development. $2,000-5,000. Worth it for any property where EPBC may apply.
3. Factor the federal layer into the price. A property with EPBC exposure should sell at a discount that reflects the additional cost and uncertainty.

EPBC is the most expensive layer in the Australian planning system, but it applies to a relatively small number of properties. Knowing whether yours is one of them before exchange is the difference between a development that proceeds on time and budget and one that gets caught in 18 months of federal assessment.
