GBB interactive map

AEMO's 2026 Gas Bulletin Board Biennial Review survey is now open. We encourage all users to share their feedback before submissions close on 11 September.

From 24 August, users may notice higher EGP flow values on the GBB Interactive Map. This reflects a change in how the map reports EGP flows.

Previously, the map displayed EGP flow at the Longford Hub, which excluded supply from the Orbost Gas Plant. From 24 August, the displayed EGP values will incorporate the Orbost Gas Plant supply and regional Victoria demand, better representing the pipeline utilisation and the northbound flows supporting New South Wales.
