  • Commencement within a 12-month window, starting 1 July 2025.
  • Provides buyer and seller with both certainty and flexibility as Mahalo Gas Hub is progressed into production.

Comet Ridge has executed a seven-year Gas Sales Agreement (GSA) with CleanCo Queensland Limited (CleanCo), subject to approval from the Queensland Government.

This is Comet Ridge’s first GSA and is therefore an incredibly important milestone for the Company. The natural gas will be produced from the Mahalo Gas Hub in Central Queensland, where CleanCo will offtake 3 PJ per annum of natural gas.

Comet Ridge and CleanCo have agreed for supply to commence in a 12-month window between 1 July 2025 and 30 June 2026, which will allow Comet Ridge flexibility ahead of Final Investment Decision (FID) on its Mahalo Gas Hub projects.

Comet Ridge Managing Director, Tor McCaul said the execution of the GSA was a very significant milestone for the Company as it transitioned from developer to producer of gas.

“We know that East Coast Australia needs more gas for decades to support consumers and jobs in vital industries, as well as to partner with renewables as we transition to Net Zero. Comet Ridge is very pleased to be working with CleanCo to bring a new source of energy to Queensland that will make a valuable contribution to energy security, and to enable CleanCo to manage its overall energy mix to minimise its carbon emissions.

“For our shareholders, this is an exciting development as it is a major milestone towards taking FID on the development of our natural gas reserves in the Mahalo Gas Hub.”

Mr McCaul said Comet Ridge would continue to develop its Mahalo Gas Hub portfolio, which held 406 PJ of 2P and 2C reserves and resources. “The Mahalo Gas Hub has the potential to be a multi-decade, low-cost, high production project which has great access to infrastructure and potential for significant resource upside. We are at the beginning of an opportunity to make a valuable contribution to East Coast Australia’s energy security for many years to come.”

Other gas marketing

Comet Ridge has had strong interest in Mahalo Hub gas and is in discussions with several parties regarding further gas supply contracts. The Commonwealth Government intervention into the gas market this year has had a major impact on gas marketing generally, with both buyers and sellers having to deal with more uncertainty. However, with the Gas Market Code now effective from 11 September, and significant exemptions for smaller producers, the market is returning to a more normal operating condition and confidence is coming back into the market.
