Offshore petroleum exploration acreage release process

The government releases areas in Australian Commonwealth waters for oil and gas exploration each year.

Subscribe to Australian Petroleum News for information on acreage bidding rounds, and for updates on offshore oil and gas matters in Australian Commonwealth waters. Oil and gas companies can participate in the acreage release by:

  • suggesting areas for future exploration in the nomination process
  • bidding to explore release areas 

Anyone who has an interest in areas that may be released for bidding can have their say during the consultation.

Nominate areas for future exploration

The offshore petroleum industry is invited to shape the acreage release each year. You can submit nominations for release areas to be considered.

Nominations for the 2023 acreage release are now open.

Before you start

Your nomination should demonstrate a genuine intent to start activities in the immediate term. As a guide:

  • If you represent an exploration and production company, your nomination would indicate a strong interest in exploring the area and potentially bidding in the next scheduled acreage release.
  • If you represent a geophysical company, you are expected to have recent non-exclusive data products over the nominated area available during the next July to March bidding period.

We do not place limits on the number of nominations you can put forward. However the government may change this if:

  • areas are not routinely bid on
  • nominations consistently lack a well-considered rationale

The Joint Authorities must consider and endorse release areas before they can progress to the bidding rounds. The Joint Authority is generally made up of the responsible federal minister and the relevant state or Northern Territory minister.

Submitting your nomination

Complete the online nomination form on

Please nominate non-contiguous areas separately.

In some cases we don't progress nominations. Nominated areas, or parts of areas, may be excluded for various reasons including:

  • national security, for example if they impact international maritime boundaries
  • legal, for example if a nominated area extends into a green or yellow Australian marine park zone
  • where precompetitive open-file studies of the geology or other features of the area are being undertaken
  • where exploration activities may impact other marine users or biologically important areas

See the National Offshore Petroleum Titles Administrator (NOPTA) interactive map to determine if your nomination may be affected.

You must provide reasons for nominating an area. This is crucial in frontier areas with limited infrastructure or social licence to operate.

The government consults with other commonwealth, state and territory agencies before public consultation. The government will consider their priorities when deciding to release acreage in an area.

Consultation on release areas

Before areas are released for bidding, the government undertakes a consultation process. We seek feedback from anyone who has an interest in a specific area and can provide information relevant to exploration in that area. This includes:

  • other government agencies
  • the public
  • other marine users, like the fishing, aquaculture and tourism industries

To be notified of upcoming consultations subscribe to the Australian Petroleum News.

Consultation informs the Joint Authorities’ decision to release nominated areas. It also helps companies understand factors they may need to consider when applying for and working in an area.

We consulted on areas for inclusion in the 2021 acreage release. View details and feedback from stakeholders on Consultation hub.

Bidding for exploration permits

The Joint Authorities invite companies to bid on release areas. Areas available for bidding, and bid due dates, are published in the Australian Government Gazette

Applying as a foreign investor

If you’re a foreign investor, you should familiarise yourself with Australia’s foreign investment framework. Failure to comply with the law may result in penalties.

You’re responsible for obtaining any relevant Foreign Investment Review Board (FIRB) approvals.

You must submit evidence of your FIRB approval with your application to NOPTA. If your FIRB approval is pending, provide evidence of this to NOPTA with your application.

NOPTA will not offer petroleum exploration permits until they receive the required FIRB approvals.
