Project overview




On 19 April 2017, the Australian Government directed the ACCC to conduct a wide-ranging inquiry into the supply of and demand for natural gas in Australia, and to publish regular information on the supply and pricing of gas for the next 3 years.

On 25 July 2019, the Treasurer wrote to the ACCC extending the inquiry until December 2025.

On 25 October 2022, the Government extended the ACCC's gas inquiry role through to 2030.

Scope of inquiry

The inquiry will monitor and consider matters including:

  • the pricing and availability of offers to supply gas
  • the volumes of gas supplied or available for current or future supply, including natural gas extracted or produced in Australia, or imported into Australia
  • the pricing, volume and availability of gas for domestic supply compared to the pricing, volume and availability of gas for export
  • the pricing, volume and availability of other goods or services, such as goods or services for drilling, storing or processing gas, that enable, assist or facilitate the supply of gas or gas transportation services in Australia.

Providing information to the inquiry

When requested to do so in a notice or determination, you should provide information and documents to the ACCC using the ACCC data portal.

Submit data to the ACCC

Companies that would like to share their recent experience in the gas market, or broader concerns about the gas industry, can email the ACCC at
