NOPSEMA assessed CGG Regia's submission for a marine seismic survey regarding protected matters impacts, particularly on Southern Right Whales (SRWs). Assessment notes from December 2025–January 2026 identified significant concerns across multiple areas. Modelling discrepancies were not adequately explained in the Environment Plan, with large unexplained reductions in predicted effects attributed to the Animat software and differences in weightings and thresholds. NOPSEMA required stronger justification for demonstrating acceptable impact levels to SRWs linked to recovery plans. Additional issues included inconsistencies in Environmental Performance Objectives (EPOs), ambiguities in defined acceptable levels, and incomplete controls in mitigation scope. The review noted recent published research on seismic impacts to fish species and flagged consultation matters requiring internal discussion. The activity description and operational area definitions required clearer delineation per relevant guidelines.
