These areas are set aside to be drawn on for future GHG Acreage Release.
As such, the reserved areas shall not be the subject of a GHG exploration permit, GHG drilling reservation, GHG retention lease, GHG injection licence, GHG special prospecting authority or GHG access authority.
The reservation of these graticular blocks remains in effect until 16 October 2027 unless otherwise varied or revoked.
