The proposal would introduce an East Coast Gas Reservation that would require an additional 50-100 petajoules of gas - equivalent to 10-20% of current east coast gas demand - to be committed to the domestic market in the first 12 months of operation. The additional gas will be shared across the three largest east coast gas exporters.

Detailed design of the mechanism, in consultation with industry and consumers, would occur in early 2025-26.

The proposal would start from 1 July 2025.
