- ExxonMobil: Partnered with Woodside in the Bass Strait (off Victoria), ExxonMobil is a major player in eastern Australia’s oil and gas production, though its focus has shifted toward maintaining aging fields.
- Shell PLC: Shell operates the Prelude floating LNG facility, the world’s largest of its kind, off Western Australia, and holds stakes in other LNG ventures like Queensland Curtis LNG (QCLNG).
- TotalEnergies SE: This French multinational is involved in offshore exploration and production, particularly in the Browse Basin, contributing to Australia’s LNG export capacity.
- BP PLC: While BP closed its Kwinana refinery in 2021, it remains active in exploration and retail fuel distribution, maintaining a foothold in the downstream sector.
These companies dominate the upstream (exploration and production) and midstream (LNG processing and pipelines) segments, with foreign players often bringing capital and technology to complement local expertise.
Geographic Hotspots of Industry Activity
Australia’s oil and gas resources are concentrated in specific regions, largely dictated by geological basins and proximity to export markets.
- North West Shelf (Western Australia): The epicenter of Australia’s industry, this offshore region includes the Carnarvon, Browse, and Bonaparte basins. It’s the heart of LNG production, with supergiant gas fields like Gorgon and North Rankin driving exports to Asia.
- Cooper-Eromanga Basin (South Australia and Queensland): A major onshore area, this basin is a hub for conventional oil and gas, supplying domestic markets. It’s one of the few regions with significant land-based production.
- Gippsland Basin (Victoria): Located offshore in southeastern Australia, this basin has historically been a key source of oil and gas for the east coast, though production is declining.
- Perth Basin (Western Australia): An emerging onshore and nearshore area, it’s gaining attention for gas discoveries like the Lockyer Deep project.
- Otway Basin (Victoria and South Australia): This region supports smaller-scale gas production, with recent discoveries boosting its relevance for domestic supply.
Western Australia dominates the industry, accounting for over 80% of oil and gas production, primarily offshore. Eastern states like Victoria and Queensland contribute through onshore basins and legacy offshore fields, but their output is dwarfed by the northwest.
Key Formations and Extraction Methods
Unlike the U.S., where shale gas and hydraulic fracturing (fracking) dominate, Australia’s industry focuses on conventional resources and LNG development.
- Conventional Gas and Condensate: The North West Shelf’s giant gas fields (e.g., Gorgon, Jansz) produce vast quantities of natural gas and condensate (liquid hydrocarbons extracted with gas). These are processed into LNG for export or used domestically.
- Coal Seam Gas (CSG): In Queensland, CSG is a major focus, particularly for LNG projects like QCLNG and Gladstone LNG. Extracted from coal beds, it’s a significant departure from traditional reservoirs but doesn’t rely on fracking to the extent seen in U.S. shale plays.
- Tight Gas and Shale Potential: While Australia has shale and tight gas resources (e.g., in the Canning Basin), their development lags behind conventional plays due to high costs, remoteness, and regulatory hurdles. Fracking is used sparingly, mostly in experimental phases, and faces public opposition in some states.
- Offshore Subsea Technology: Advanced subsea systems and floating LNG platforms (e.g., Shell’s Prelude) are critical for tapping deepwater reserves, reflecting Australia’s focus on offshore innovation over unconventional onshore methods.
The emphasis on LNG and conventional offshore gas sets Australia apart from fracking-heavy regions like the U.S., aligning with its export-driven strategy.
Offshore vs. Onshore Drilling Trends
Australia’s drilling activity is heavily skewed toward offshore operations, reflecting its resource base and infrastructure.
- Offshore Drilling: Approximately 88% of petroleum production in 2024 came from offshore fields, primarily in the North West Shelf and Gippsland Basin. Projects like the Sasanof-1 well (Western Australia) and Artisan-1 (Otway Basin) highlight ongoing exploration. Offshore rigs face high costs and technical challenges but benefit from vast reserves and proximity to export ports.
- Onshore Drilling: Onshore activity is concentrated in the Cooper-Eromanga and Perth basins, with smaller contributions from CSG in Queensland. Recent discoveries like Lockyer Deep-1 signal growth potential, but onshore production remains a fraction of offshore output. Victoria’s lifting of a conventional gas drilling ban in 2021 has spurred modest activity.
Offshore dominance is unlikely to shift soon, given the scale of LNG projects and declining onshore oil reserves. However, onshore gas is gaining traction for domestic supply as east coast shortages loom.
Infrastructure: Pipelines, Refineries, and Expansion
Australia’s oil and gas infrastructure is robust but faces challenges from aging assets and a shrinking refining sector.
- Pipelines: The country boasts over 39,000 kilometers of natural gas transmission pipelines, connecting offshore fields to LNG plants and onshore basins to urban centers. Key systems include the Dampier-to-Bunbury Pipeline (Western Australia) and the SEA Gas Pipeline (Victoria to South Australia). New pipeline projects are underway to bolster domestic supply, supported by government initiatives.
- Refineries: Australia’s refining capacity has dwindled, with only two operational facilities remaining: Ampol’s Lytton refinery (Queensland) and Viva Energy’s Geelong refinery (Victoria). BP’s Kwinana closure in 2021 and ExxonMobil’s Altona shutdown in 2021 reflect competition from Asian mega-refineries. The government has pledged up to USD 1.8 billion through 2030 to keep these refineries viable, emphasizing fuel security.
- LNG Facilities: Australia’s LNG infrastructure is world-class, with plants like Gorgon (15 million tons per annum), Wheatstone, and Prelude driving export growth. Expansion continues, with Woodside and ExxonMobil’s $350 million Bass Strait drilling campaign (announced in 2025) aimed at extending supply.
- Storage and Ports: The government is expanding crude oil storage by 7-15 million barrels to enhance resilience, while ports like Dampier and Port Hedland handle massive export volumes.
Infrastructure development prioritizes LNG exports and domestic gas security, but refining’s decline increases reliance on imported fuels.
Petroleum Imports, Exports, and Global Trade
Australia’s oil and gas trade profile is paradoxical: it’s a major LNG exporter yet heavily dependent on imported refined products.
- Exports: In 2021-22, over 85% of Australia’s 891 petajoules (PJ) of crude oil, condensate, and LPG production was exported, primarily from Western Australia. LNG exports, valued at billions annually, target Japan, China, and South Korea. Crude oil exports (e.g., to Indonesia and Singapore) totaled 623 PJ in 2021-22, with earnings spiking to AUD$14 billion amid high oil prices post-Russia’s Ukraine invasion.
- Imports: Australia imports 83% of its oil needs, including crude for refining and refined products like gasoline and diesel. In 2022, only 15% of refinery feedstock was domestic, with Asia (40%), Africa (18%), and the Middle East (17%) supplying the rest. This reliance stems from declining local oil production and refinery closures.
- Global Role: As a top LNG exporter, Australia stabilizes Asian energy markets, contributing to Paris Agreement goals by displacing coal. However, its oil import dependence exposes it to supply chain risks, especially through chokepoints like the Strait of Hormuz.
The trade imbalance underscores Australia’s focus on gas exports over oil self-sufficiency, a strategic choice shaped by geology and economics.
Industry Employment
The oil and gas sector supports around 80,000 direct and indirect jobs in Australia, with ripple effects across manufacturing and services.
- Workforce Distribution: Most jobs are in Western Australia, tied to offshore LNG projects and pipeline operations. Regional hubs like Karratha and Dampier host fly-in, fly-out (FIFO) workers, while Perth is an administrative and engineering base. Eastern states employ fewer workers, mainly in onshore fields and refineries.
- Skills and Trends: High demand exists for engineers, geologists, and subsea technicians, driven by offshore complexity. However, employment growth is tempered by automation and a lack of new mega-projects compared to the 2010s LNG boom.
- Community Impact: FIFO jobs boost rural economies, but the industry’s capital-intensive nature limits job creation relative to output. Transition pressures toward renewables also loom, though gas’s role in the energy mix sustains demand for now.
Regulatory Landscape and Comparisons
Australia’s regulatory framework balances industry growth with environmental and social concerns, differing from other oil-producing nations.
- Key Regulations: The National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) oversees offshore activities, enforcing strict safety and environmental standards. Onshore, state governments regulate, with variations—e.g., Victoria’s past fracking ban (lifted for conventional gas in 2021) versus South Australia’s permissiveness.
- Ease of Operation: Compared to Canada’s regulatory uncertainty or the U.S.’s patchwork of state rules, Australia’s federal-state system is relatively streamlined for offshore projects. Tax incentives and the 2021 Offshore Petroleum Bill enhance decommissioning efficiency, attracting investment.
- Challenges: Public opposition to onshore fracking and carbon emissions caps complicate unconventional plays. Unlike Middle Eastern producers with minimal environmental oversight, Australia’s net-zero goals by 2050 push decarbonization, though LNG is framed as a transitional fuel.
Australia’s regulatory clarity aids offshore giants, but onshore constraints lag behind freer markets like Texas.
Energy Transition and Future Outlook
- Energy Transition: The 2024 Future Gas Strategy outlines gas’s role in reaching net zero, with investments in carbon capture (e.g., Gorgon’s CCS) and hydrogen exploration signaling a shift. Companies like Woodside and Chevron are diversifying into renewables, reflecting global trends.
- Declining Oil Reserves: With 2P oil reserves at 1,475 PJ (251 million barrels) in 2022 and no major discoveries, domestic crude production could cease within six years without breakthroughs, heightening import reliance.
- Geopolitical Risks: Australia’s dependence on Asian refineries and Middle Eastern crude exposes it to disruptions, prompting a fuel security review and stockpile expansion.
Australia’s oil and gas industry is a tale of contrasts – a global LNG powerhouse with cutting-edge offshore capabilities, yet a nation grappling with dwindling oil reserves and refinery losses. For industry workers abroad, it offers lessons in leveraging geology for export success, navigating import dependence, and adapting to a decarbonizing world. The sector remains a dynamic player, driven by giants like Woodside and Chevron, but its future hinges on balancing energy security, trade, and sustainability.
