When a developer wants to clear land to build a warehouse, or a mining company wants to build a coal mine, Australian law typically requires that they ‘offset’ the damage they cause to nature as a condition of the planning approval. The concept of an offset relies on the idea that an approved harm to the environment and an environmental benefit secured elsewhere are interchangeable. If you destroy koala habitat in one place, then you must secure safe koala habitat elsewhere.
This is called ‘like-for-like’, and it is essential to the idea of what an ‘offset’ is and does. Of course, as carbon offsetting has taught us, rarely does this logic translate to good outcomes for the environment.
In practice, there are deep problems with the integrity of the nature ‘credits’ that are used to offset damage done by developers. This includes time lags between when the damage occurs and the offset is secured, which increases the risk of exacerbated or unanticipated harm to the impacted species; failure to protect sites in perpetuity even though the impact is permanent, resulting in a net loss; and a failure to effectively and transparently manage and monitor sites. These problems mean national biodiversity offset arrangements under Australia’s flagship federal environment law, the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), are leading to worse overall environmental outcomes. As noted by former Environment Minister Tanya Plibersek in the early days of the first Albanese Government, Australia is a world leader in species extinction, and holds the dubious record of sending more mammal species extinct than any other continent.
Departmental audits have found that offsetting requirements under the EPBC Act are simply not being complied with, that projects are going ahead without first securing the necessary offsets, or that sites supposedly secured for habitat protection are in a worse condition than they were before. The damage is being done, but the commensurate protection isn’t being secured.
All of this contributes to the general outlook for Australia’s unique and precious environment: poor, deteriorating, and under increasing threat. As much was recognised by Professor Graeme Samuel AC in his review of the EPBC Act, provided to the Federal Government five years ago.
So, what is the Albanese Government doing about this problem? Our new paper shows that they’re promising to make it worse.
The Environment Protection Reform Bill 2025, introduced to Parliament in late October, will, among other things, amend the EPBC Act to expand and further weaken the national biodiversity offsetting arrangements that are already failing so badly.
Most troublingly, under the changes, developers won’t even need to pretend to secure a ‘like-for-like’ offset for the nature they destroy. Instead, the Environment Minister can simply decide that the developer need merely pay a ‘Restoration Contribution’ into a centralised fund as a condition of approving their project. The ‘Restoration Contribution Holder’, a new statutory appointment, will spend the money with the purpose of compensating for the specific damage and achieving a ‘net gain’ in nature protection—but with plenty of leeway should that prove to be not ‘feasible’.
Essentially, this means developers may simply be able to ‘pay to destroy.’
Intuitively, this seems far removed from the like-for-like logic underpinning the concept of offsetting. It is also a tacit admission of what many in biodiversity conservation have long known: biodiversity offset ‘markets’ are perennially short of supply. There will always be a pipeline of proposed developments that will have a harmful impact on nature, but for which the corresponding environmental protections aren’t available, or aren’t even possible.
