**100 million litres** of additional diesel have been secured by the Albanese Government under new strategic reserve powers, with shipments arriving from Brunei and South Korea on April 16. This represents the first use of the Government's new fuel security legislation that passed on April 1, demonstrating the practical implementation of powers designed to shield Australia from global fuel supply disruptions. The successful deployment of these reserve powers reduces regulatory uncertainty around fuel security interventions and validates the policy framework for future supply chain resilience investments. **Fuel excise has been halved for three months** following a National Cabinet meeting on March 30, directly reducing petrol and diesel costs for consumers and businesses. The temporary measure runs alongside new fuel security powers established on March 28 and follows minor adjustments to diesel standards on March 24 to increase domestic supply availability. This coordinated policy response signals the Government's willingness to use both fiscal and regulatory tools to manage fuel market pressures, creating a more predictable intervention framework for energy market participants.

Australian Energy Regulator

The AER has published its final determination on Transgrid's Central-West Orana Enabling Project for the 2026–31 regulatory period. This transmission infrastructure project is critical for connecting the Central-West Orana Renewable Energy Zone to the grid. The final approval provides regulatory certainty for developers planning renewable projects in this REZ and confirms the transmission investment framework that will underpin the region's clean energy development. The AER opens consultation on Framework and Approach papers for Transgrid, ElectraNet and Murraylink's 2028–33 revenue determination, with submissions closing 8 May 2026. This consultation will establish the regulatory framework governing transmission pricing and investment decisions across key interconnectors and networks in NSW, SA and Victoria for the next regulatory period. The outcomes will directly impact transmission costs and investment signals for renewable energy projects seeking grid connection from 2028 onwards.

Townsville Hydrogen Project Abandoned After Failure to Secure Offtake Agreements

A planned hydrogen production project in Townsville has been scrapped after developers were unable to identify buyers for the product, according to reporting by RenewEconomy dated 20 April 2026. The cancellation reflects a broader demand-side constraint in the Australian hydrogen sector, where upstream production capacity has proceeded ahead of confirmed end-user commitments. The project's collapse adds to a growing number of Australian hydrogen initiatives that have stalled or been abandoned at pre-final-investment-decision stages. The inability to secure offtake agreements prior to project commitment underscores material commercial risk for hydrogen developers and financiers operating in the current Australian market, and may prompt closer scrutiny of demand-side assumptions underpinning business cases submitted under federal and state hydrogen support programs. Investors and project proponents should assess whether existing pipeline projects carry adequately contracted revenue before progressing to further development expenditure.
