Offshore petroleum exploration acreage release process

The Australian Government releases oil and gas exploration areas in Australian Commonwealth waters each year. Companies can nominate and bid for these areas.

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 when we consult on nominated areas.

Acreage release process overview

All operational activities are subject to regulatory approval by the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA). This includes:

  • comprehensive consultation with all key stakeholders
  • consideration of potential impacts and risks to the environment
  • proposed management and mitigation of those risks.  

Nominating 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.

2023 acreage release

Nominations for the 2023 Offshore Petroleum Exploration Acreage Release closed on 1 September 2022.

The nominations portal is open year-round. Submissions made after 1 September 2022 will be considered as part of any future offshore acreage release.

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 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 will consider their priorities when deciding to release acreage in an area.

Selection of nominated areas

The minister considers a range of factors when selecting nominated areas for public consultation. These include:

  • national security and maritime boundaries
  • environmental regulations
  • commercial interest
  • proximity to markets and supporting infrastructure
  • social licence to operate
  • other marine users and offshore titleholders
  • strategic priorities of the government.

We also consult with:

  • state and territory governments
  • other Australian Government agencies.

Consultation on area nominations

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 Resources 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 2022 acreage release. View details and feedback from stakeholders on our consultation hub.
