Due Diligence Assessments

Queensland Ecologists provides due diligence assessments for developers, investors, and landholders who need to understand the ecological constraints and opportunities on a property before committing to a purchase or project. Our assessments give you a clear, honest picture of what you are dealing with - so you can make informed decisions and reduce approval risk before you commit to purchase, design or lodgement.

A due diligence assessment is one of the smartest investments you can make at the early stages of a project. The cost of identifying a significant ecological constraint after purchase or after design is locked in can be significantly greater than the cost of identifying it upfront.

What Is a Due Diligence Assessment?

A due diligence assessment is a pre-purchase or early-stage ecological investigation designed to identify environmental constraints and opportunities on a property or project site. It combines desktop analysis of government mapping layers and databases with a preliminary field inspection to verify on-ground conditions.

The assessment identifies constraints such as remnant and regulated vegetation, waterways and wetlands, threatened species habitat, environmental overlays, and any existing environmental obligations or encumbrances on the land. It also identifies opportunities - areas where development may be more straightforward, potential for environmental offset credits, or ecological values that could add to a project’s amenity and marketability.

Unlike a full ecological assessment prepared for a development application, a due diligence assessment is designed to be rapid, practical, and decision-focused. It gives you the information you need to decide whether to proceed, what further investigations may be required, and what the likely approvals pathway looks like.

When Do You Need a Due Diligence Assessment?

Due diligence assessments are most valuable when you still have the ability to walk away or adjust your plans. Common triggers include:

• Property purchase - developers and investors - Before purchasing land for development, a due diligence assessment identifies ecological constraints that could affect yield, increase costs, or delay approvals. This is essential for developers buying broadhectare land in SEQ’s growth corridors, where remnant vegetation and waterway buffers can significantly reduce developable area.
• Early project feasibility - During the feasibility stage of a development or infrastructure project, understanding ecological constraints helps inform concept design, financial modelling, and risk assessment. A due diligence assessment at this stage can prevent costly redesign later.
• General Environmental Duty (GED) - Under section 319 of the Environmental Protection Act 1994, every person in Queensland has a General Environmental Duty to take all reasonable and practicable measures to prevent or minimise environmental harm. A due diligence assessment helps landholders and project proponents understand their GED obligations and demonstrate they have taken reasonable steps to identify and manage environmental risks.
• Vendor due diligence - Vendors selling land with known or suspected ecological values can commission a due diligence assessment to provide prospective buyers with transparent information, facilitating a smoother transaction and reducing the risk of post-sale disputes.
• Joint venture and partnership decisions - When entering a joint venture or partnership arrangement involving land, an independent ecological due diligence assessment provides all parties with an objective understanding of the site’s constraints and opportunities.

Our Process

Our due diligence assessment process is designed to deliver actionable information within tight timeframes. We understand that property transactions and feasibility decisions often move quickly, and we structure our assessments accordingly:

1. Desktop constraint mapping - We conduct a comprehensive desktop analysis of all relevant mapping layers and databases, including:
   • Regulated vegetation mapping (remnant and high-value regrowth) under the Vegetation Management Act 1999
   • Waterways and wetlands mapping under the Water Act 2000 and State Planning Policy
   • Matters of State Environmental Significance (MSES) mapping
   • Matters of National Environmental Significance (MNES) protected matters search
   • Essential habitat and wildlife habitat mapping
   • Local government planning scheme overlays (environmental significance, waterway corridors, biodiversity, scenic amenity)
   • Contaminated land register and environmental management register
   • Existing approvals, covenants, and environmental encumbrances on the title
2. Risk assessment - We assess the significance of identified constraints in the context of your proposed use or development intent. Not all constraints are equal - some can be readily managed through design, while others may be project-defining. We provide a clear risk rating for each constraint.
3. Preliminary field inspection - Our ecologists conduct a site inspection to verify the accuracy of desktop mapping, assess on-ground conditions, identify any ecological values not captured in mapping (such as threatened species habitat or significant fauna habitat trees), and note any discrepancies between mapped and actual vegetation extent or condition.
4. Summary of approvals pathway and likely requirements - We outline the likely ecological approvals pathway for your proposed development, including which assessments and surveys will be required, which agencies will be involved (council, the Queensland Government, DCCEEW), estimated timeframes, and indicative costs for further ecological work.
5. Due diligence report - We deliver a concise, clearly structured report that summarises all findings, presents constraints and opportunities in map format, and provides practical recommendations. The report is designed to be shared with project partners, financiers, and other advisors.

A due diligence assessment is often the first step in a broader ecological assessment process. Depending on the findings, you may require:

• Ecological Constraints Analysis - A more detailed constraints and opportunities assessment, typically conducted once a decision to proceed has been made and before DA lodgement.
• MSES Assessments - Formal assessment of Matters of State Environmental Significance if your site intersects MSES mapping layers.
• EPBC Act Referrals & Assessments - If the due diligence assessment identifies potential impacts on Matters of National Environmental Significance, a formal EPBC referral assessment may be required.
• Environmental Auditing & Compliance - Once approvals are in place, we can provide ongoing compliance monitoring to ensure conditions are met.
