Introduction BP Developments Australia Pty Ltd (BP), in its capacity as operator of the proposed Great Australian Bight (GAB) Exploration Drilling Program, proposes to drill four exploration wells in Commonwealth marine waters in the GAB. Exact well locations are yet to be determined for all wells, however they will be drilled within the Ceduna 3D seismic survey area, which was acquired between November 2011 and May 2012 and covered 12,100 km2 across Exploration Permit for Petroleum (EPP) 37, EPP 38, EPP 39 and EPP 40 (herein referred to as the ‘drilling area’). The EP addresses drilling anywhere within this drilling area. The GAB exploration drilling program is
