Covered gas suppliers must publish an updated Expression of Interest (EOI) on their website and notify the Australian Energy Regulator within 3 days if the information in the EOI is no longer current.

Covered gas suppliers can be fined up to 6,000 penalty units for companies or 1,200 penalty units for individuals if they fail to update and publish a gas EOI or notify the Australian Energy Regulator.

The Australian Energy Regulator can now approve specific quantities of natural gas as 'additional gas' for the domestic market. People who have this approval can be fined up to 6,000 penalty units for companies or 1,200 penalty units for individuals if they break the conditions of that approval.

Gas producers can apply to the Australian Energy Regulator to set a 'gas production baseline'. Any gas produced above this baseline is classified as 'additional gas'.

The Australian Energy Regulator must develop and publish methods for forecasting gas supply and demand. The Regulator must also provide written estimates of gas quantities to licence holders for the next four regulated periods.

The Energy Minister can specify factors that the Australian Energy Regulator must use when forecasting gas supply and demand, provided the Minister administering the domestic gas reservation laws agrees.

Licence holders can avoid penalties for not meeting their domestic supply obligations if they can show they made a genuine effort to sell uncontracted gas. This includes publishing notices on their website and issuing gas EOIs on competitive terms.

The Australian Energy Regulator can now share information collected under domestic gas reservation laws with other entities, including the Australian Energy Market Operator, to help them perform their duties.

The Australian Energy Regulator must decide on applications for additional gas or production baselines within 60 days, though this timer pauses if the Regulator is waiting for more information from the applicant.

The Australian Domestic Gas Security Mechanism export controls, which regulated LNG exports during domestic shortfalls, are removed. These controls will only continue to apply to shortfall quarters that ended before 1 January 2028.

The Gas Market Code is simplified by removing the formal framework for 'gas initial offers' and 'gas final offers'. This gives suppliers and buyers more flexibility in how they negotiate.

The Gas Market Code no longer includes price rules for agreements to supply regulated gas, and the framework for conditional Ministerial exemptions is removed.

When a licence holder negotiates the supply of regulated gas with a non-licence holder, they must consider whether any offers were unreasonably refused and whether the proposed price and terms were fair.

Gas suppliers must keep records of all documents and information exchanged during gas EOI negotiations, including why a negotiation did not lead to an agreement.
