The Otway Offshore Gas Victoria Project (the Project) describes how Beach plans to develop gas reserves and future resources adjacent to its permits and infrastructure in the Otway Basin.

The development concept selected for the Project is a subsea tie-back to existing facilities. The stages of the Project will include an initial drilling campaign operated by a semi-submersible MODU. Successful wells will be tied back to existing Otway Gas Production Pipeline (OGPP) and/or Thylacine A platform via installation of new subsea flowlines and facilities. Recovered gas will be transported through the OGPP to the onshore OGP located onshore near Port Campbell, Victoria. The OGP supplies gas to the domestic market in south-east Australia.

The Project focuses on exploration, appraisal and development of existing and future gas discoveries in Beach’s exploration permits, VIC/P43 (including VIC/L35) and VIC/P73 (including VIC/L36) located in the offshore Otway Basin. The Project covers an area that is located approximately 17 km south of the Victorian mainland and 80 km northwest of Tasmania (King Island) at its closest points.

The Project is adjacent to Beach’s current production operations at the Geographe and Thylacine gas fields in the offshore Otway Basin. The Project Area is located north of the existing Thylacine platform and includes the locations of gas discoveries and exploration prospects within approximately 10 km of these discoveries and pipeline tie in points with corridors for subsea connections. Installation of subsea infrastructure including wellheads, flowlines, umbilicals, manifolds and skids will be undertaken to connect any gas discoveries to existing infrastructure.

The proposed scope of the Project consists of:
• Seabed surveys (geotechnical and geophysical)
• Exploration, appraisal and development drilling
• Completion of successful wells
• Subsea infrastructure installation and commissioning
• Operations and maintenance
• Decommissioning

Beach is planning the initial drilling campaign to commence in 2025, with installation of new subsea facilities commencing in 2028 and the earliest achievable date for commissioning and first gas in 2028 subject to corporate, joint venture and regulatory approvals. Production from successful prospects is expected to have an operational life of up to 20 years.
