Southern Ocean Declared Area

06 Mar 2024: On 6th March, the Minister for Climate Change and Energy declared the Southern Ocean region off Victoria, following two months of public consultation. Feasibility applications are now open, with the window lasting until 2nd July 2024. However, the declared area is around one fifth of the size of the original proposed area. It comes in at a maximum size of 1,030 km2, compared to the originally proposed area, which was 5,132 km2. The reduced size means the maximum capacity of the area has dropped from 14.6 GW to 2.9 GW. This suggests only a handful of projects will be awarded feasibility licences to conduct site investigations.
