Australia Oil And Gas Upstream Market Size, Share Outlook, Growth Analysis Report and Forecast Trends 2026-2030

Australia's upstream oil and gas sector operates under ANZSIC classification B0700 and spans major offshore basins including the Carnarvon and Browse basins off Western Australia, along with onshore basins in the Cooper-Eromanga region and emerging shale and tight gas plays. According to Geoscience Australia's 2025 energy commodity assessment, the nation holds approximately 100,255 petajoules of total discovered resources for oil, with proven and probable (2P) reserves estimated at 7,551 petajoules. The market's economic contribution extends beyond extraction to support extensive supply chains, including specialized marine services, engineering, and liquefaction infrastructure.

• •ANZSIC B0700 classifies oil and gas extraction activities, with the upstream segment representing the initial production phase
• •Australia holds approximately 7,551 petajoules in 2P oil reserves per Geoscience Australia's 2025 assessment
• •The sector is predominantly gas-weighted, with major LNG export facilities at Karratha and Darwin

Rising liquefied natural gas demand from Japan, China, and South Korea continues to anchor upstream investment decisions, with long-term contract structures providing revenue visibility for major projects. Technological improvements in subsea tiebacks and floating production systems are enabling development of remote and smaller accumulations that were previously uneconomical. Additionally, ongoing exploration activity in frontier basins like the Northern Territory's Bonaparte Basin offers upside potential for reserve replacement.

• •Asia-Pacific LNG import demand remains the primary export market driver for Australian upstream gas production
• •Advances in subsea completion and tieback technology are reducing development costs for remote offshore fields
• •Strategic petroleum reserves policies and energy security concerns support continued investment in domestic oil production

Western Australia dominates upstream activity, with the Carnarvon Basin hosting the majority of producing offshore fields and liquefaction facilities that process gas for export markets. Eastern Australia's offshore basins, including the Gippsland Basin and newer discoveries in the Otway Basin, contribute oil and gas production primarily for domestic consumption. Onshore operations in South Australia and the Northern Territory focus increasingly on unconventional gas and basin-centered oil plays, while Queensland's upstream sector remains centered on coal seam gas tied to LNG supply.

• •Western Australia accounts for the majority of upstream production volume, particularly from the North West Shelf projects
• •The Gippsland Basin in Victoria remains a key onshore and offshore oil-producing region with decades of established infrastructure
• •Northern Territory offshore projects like the Ichthys field represent some of the world's largest LNG supply developments

What are the recent trends and outlook?

The upstream market is expected to reach approximately $56 billion in total industry value by 2032 according to sector forecasts, supported by new project sanctions and sustained LNG export volumes. Decarbonization pressures and evolving emissions reduction policies are prompting operators to pursue lower-carbon development options, including carbon capture and storage projects and electrification of offshore facilities. Digitalization initiatives leveraging artificial intelligence and predictive maintenance are increasingly adopted to optimize production efficiency and reduce operational costs across remote and harsh operating environments.

• •LNG-focused growth trajectory continues, with multiple brownfield expansions and new project Final Investment Decisions expected through 2030
• •Carbon capture and storage projects like the Gorgon CCS facility reflect industry response to emissions reduction commitments
• •Remote operations automation and digital twin technologies are transforming maintenance practices for offshore platforms
