The Environment Protection and Biodiversity Conservation Act 1999 (Cth) covers three main areas.

Environmental Impact Assessment (EIA)

In particular, this involves the assessment and approval of:

Biodiversity Protection

The main tool used is the listing and management of threatened species and ecological communities.

Protected Areas

These include areas such as World Heritage sites and Commonwealth-administered National Parks.

The concept of 'Matters of National Environmental Significance' (MNES) is a political construction that does not necessarily reflect all nationally significant issues. There are 9 defined areas:

The Commonwealth can add new matters to this list by regulation. The list must be reviewed every 5 years to see whether further matters should be included. If a proposed action is likely to have a significant impact on any of the areas, it may require Commonwealth approval before it can begin. It is illegal to undertake such an action without that Commonwealth approval.

Not all actions that affect a matter of national environmental significance need Commonwealth approval. The activity must be likely to have a significant impact on the matter. Whilst the legislation is silent as to the meaning of significant impact, the government has developed guidelines to help proponents decide if this is the sort of action that needs to be referred to the Minister for assessment and approval.

Commonwealth approval is required for any action that takes place on Commonwealth land, or that is likely to affect Commonwealth land, if it has a significant impact on the environment. This extends beyond the 9 matters of national environmental significance already mentioned to include all environmental impacts.

There are some actions that may be exempt from the Commonwealth assessment and approval requirements, even if they do have a significant impact. One exception is the logging of forests in areas that are covered by a Regional Forest Agreement (RFA).

Under the Environment Protection and Biodiversity Conservation Act 1999 (Cth) (EPBC Act), an action includes a project, a development, an undertaking, an activity or series of activities, or an alteration to any of these things [s 523]. An action could be construction, expansion, alteration or demolition of buildings, structures, infrastructure or facilities, mineral and petroleum resource exploration and extraction, waste disposal, earthworks, vegetation clearance, aquaculture, and other dealings with land [see Significant Impact Guidelines 1.1 - Matters of National Environmental Significance].

An action is not the granting of a government approval [s 524]. For example, the need for an export licence, or the provision of Commonwealth funding, does not itself trigger the operation of the Act. This distinguishes the arrangements under the EPBC Act from earlier Commonwealth controls which were often targeted at funding or approval mechanisms to trigger environmental assessment.

The Environment Protection and Biodiversity Conservation Act 1999 (Cth) does not define what it means by the word significant, however its meaning is crucial to determining whether or not Commonwealth assessment and approval is required.

Under the Significant Impact Guidelines, factors to consider in determining significance include:

The current Guidelines provide the information necessary to determine whether an activity (action) may have a significant impact on a matter of national environmental importance and thereby trigger Commonwealth responsibility.

For the Commonwealth Government (Environment Minister) to know that an action requires assessment, it must first be made aware of the proposed action. The process of telling the Minister about a proposed action is known as referral. This referral can be made by the person proposing the activity (such as a developer or landowner), by another Minister, or by a Commonwealth or State Government agency or local council.

In practice, a member of the public may refer a proposed action or development to the Commonwealth Minister, however the Minister is not legally obliged to respond. If a member of the public believes the proposed activity should be referred, they can either ask the person proposing the activity or a State or Commonwealth agency or Minister to make the referral.

Once the referral is made, the proposed activity is assessed to decide whether it requires approval under the Environment Protection and Biodiversity Conservation Act 1999 (Cth) (EPBC Act). If the action is assessed to be likely to have significant impact on a matter of national environmental significance, then it will be declared to be a controlled action that requires Commonwealth environmental impact assessment and approval. Once the action has been declared a controlled action, the Minister publishes a notice to that effect on the EPBC Act Public Portal.

Once assessed, the Minister will either approve or reject the proposed action. Mostly, actions are approved subject to specific conditions. For example, a condition may be that a bond be provided as security for the action, or that the action be subject to independent environmental auditing. If the developer does not follow these conditions, or approval has not been acquired for an action that requires approval, legal action can be taken by the Minister to stop the action continuing. To learn more, visit the Department of Climate Change, Energy, the Environment and Water website.

The Minister can also prosecute the developer for any illegal action that has occurred. The Minister may decide to revoke or suspend an approval where the approval or any conditions have been breached, or the impacts of the action were inaccurately identified due to negligence or deliberate omission on the part of the developer.

There are a number of Environment Protection and Biodiversity Conservation Act 1999 (Cth) (EPBC Act) decisions that allow formal public participation. Once notice has been given about the assessment of a proposed action, the public usually has 10 business days to lodge a submission. Submissions can be made through the EPBC Act Public Portal.

The Minister must then make the decision regarding the referral within 20 business days of receiving the referral, unless further information is needed. In making the decision the Minister must consider public comments. The Minister must give notice of, and the reasons for, the decision to the person proposing the action.

There is no general right of appeal against the Minister's decision. The only mechanism that can be used to challenge the Minister's decision is judicial review by the Federal Court if the Minister has made an error of law in making the decision.

The public may have further rights to comment during the environmental impact assessment process depending on the type of process undertaken.

The Environment Protection and Biodiversity Conservation Act 1999 (Cth) (EPBC Act) does not necessarily override State law. The Act establishes assessment and approval requirements that are to be considered in addition to existing approvals required under State law. This means that an action still needs to be approved under all applicable State laws as well as under the EPBC Act. Under the Act, the Commonwealth can enter into a bilateral agreement with the State or Territory, which has the effect of delegating the Commonwealth's assessment and approval powers to the State or Territory Government. There is a current bilateral agreement between South Australia and the Commonwealth.

If a person believes that the Environment Protection and Biodiversity Conservation Act 1999 (Cth) (EPBC Act) has been or will be breached, it is possible for an individual or a conservation group to take legal action to prevent the breach or anticipated breach. Usually this will only be necessary where the Minister has not responded to calls to take enforcement action. For example, an application to the court can be made seeking an injunction to stop illegal work from proceeding.

To bring such an action, the person or group taking the action must be an "interested person". This means that the person or group must have established environmental credentials. Usually, this means having been involved in a series of activities to protect the environment for a period of at least the past two years. If an organisation is bringing the legal action, then the objects of that organisation must include the protection of the environment.

If harm to the environment is about to occur, action must be taken quickly to apply for an injunction. In urgent cases it is best to obtain legal advice from the Environmental Defenders Office or a private lawyer to determine what options are available. Alternatively, you can contact the Department for the Environment to request government intervention. The EPBC Act provides for civil and criminal penalties that can be applied to any breach. Penalties can range with fines up to $550,000 for an individual and $5.5 million for a corporate body.
