Biodiversity credits: opportunity, risk and the importance of getting the structure right

Biodiversity credits are emerging as an important opportunity for Australian landowners seeking to unlock value from land while contributing to measurable environmental outcomes. For farmers and landholders with lower-productivity or marginal land, these arrangements can provide a new pathway to long-term income, improved land use and alignment with a changing regulatory environment.

However, biodiversity credits are not a simple or passive income stream. They are a sophisticated land strategy with tax, cash flow, valuation and timing considerations that must be understood before an agreement is entered into. The issue is not that biodiversity credits are inherently flawed; it is that poor structuring and inadequate advice can turn a genuine opportunity into a financial pressure point. 

The tax issue that needs to be understood

Under current Australian Taxation Office guidance for relevant NSW biodiversity stewardship arrangements, entering into a Biodiversity Stewardship Agreement can trigger Capital Gains Tax (CGT) consequences when biodiversity credits are created, rather than only when those credits are eventually sold. This means a landowner may have a tax liability calculated by reference to the market value of credits at creation, even if those credits have not yet generated cash.

This timing mismatch is the central commercial challenge. A project may look attractive on paper, but if tax arises before sale proceeds are received, the landowner needs a clear plan for how that liability will be funded. Without that planning, the arrangement can create the classic problem of being asset rich but cash flow poor. 

Why outcomes differ between landowners

There is usually a clear distinction between biodiversity credit projects that create long-term value and those that lead to financial stress. The difference is rarely the scheme itself. More often, it comes down to the quality of the planning, assumptions and advice applied at the outset.

Projects can underperform where landowners rely on optimistic sale timelines, inflated or unsupported valuations, or assumptions that credits will be sold quickly. They can also become difficult where there has been no detailed modelling of tax obligations, cash flow requirements, management costs and long-term land commitments.

By contrast, well-structured projects tend to treat biodiversity credits as a business decision. They model tax and cash flow together, stress-test timing assumptions, seek defensible market valuations and consider whether pre-sales or early buyer engagement could reduce liquidity risk. 

A timing-driven strategy, not just a valuation exercise

Biodiversity credits are often discussed in terms of headline value. While valuation is important, timing is just as critical. A strong underlying opportunity can still create pressure if the tax profile, sale timeline and funding strategy are not aligned.

Landowners should consider the full lifecycle of the credits, including potential tax consequences on creation, sale and any subsequent use or retirement. They should also assess the practical realities of the market, including buyer demand, credit type, liquidity, pricing evidence and the time it may take to realise cash. 

Key questions before entering an agreement

Before committing to a biodiversity credit arrangement, PKF recommends landowners ask five practical questions:

1. When will the tax liability arise, and how will it be calculated?
2. How will the liability be funded if credits are not sold quickly?
3. What is the realistic sale timeline for the relevant credit type?
4. Is the valuation supported by current market evidence?
5. Does the arrangement fit the broader land, business and succession strategy?

If these questions cannot be answered clearly, the landowner should pause and seek advice before proceeding. Biodiversity credits can be valuable, but they require the same level of commercial discipline as any other significant investment decision. 

How PKF supports landowners

PKF works with farmers and landowners to assess biodiversity credit opportunities from both a tax and commercial perspective. This includes modelling tax and cash flow outcomes upfront, stress-testing different sale and pricing scenarios, reviewing valuation assumptions and helping determine whether the proposed structure is commercially sustainable.

The aim is not simply to determine whether biodiversity credits are “good” or “bad”. The more useful question is whether the arrangement has been structured so the tax, cash flow and long-term obligations work together.
