Australia's Energy Crossroads: Global Conflict, Grid Transformation, and Fiscal Strain

A confluence of events—including conflict in the Middle East, domestic energy policy shifts, and state-level fiscal pressures—has created a complex landscape for Australia, impacting fuel prices, electricity generation, and government budgets. This report synthesizes developments across these domains, presenting a comprehensive and neutral account of facts and statements from multiple sources.

Middle East Conflict and Global Energy Markets

Impact on Fuel Supply and Prices

Global oil prices have risen by approximately 10%, and analysts forecast Australian petrol prices could increase by about 40 cents per litre.

The conflict in the Middle East, including threats to the Strait of Hormuz and attacks on infrastructure in Iran and Qatar, has disrupted global oil and liquefied natural gas (LNG) supply. Unleaded petrol prices in Melbourne rose from an average of $1.76/L on February 20 to approximately $2.50/L in subsequent weeks. Diesel prices also rose significantly.

Australia imports about 90% of its liquid fuel, making it susceptible to global price spikes. The nation's emergency strategic fuel reserves are reported to be lower than International Energy Agency (IEA) recommendations.

The Australian Competition and Consumer Commission (ACCC) received over 500 reports of potential price-gouging at petrol stations and announced an investigation into alleged anti-competitive practices concerning diesel supply by major suppliers Ampol, BP, Mobil, and Viva Energy. Many service stations across Victoria and the nation reported shortages of diesel and petrol.

Governmental Responses

• The federal government halved the fuel excise for three months, reducing the cost by 26.3 cents per litre.
• Energy Minister Chris Bowen announced the release of 519 million litres of additional petrol and diesel from reserves.
• The government is exploring options for a new levy on gas companies' windfall profits, including a flat 25% tax on gas exports. The Department of Prime Minister and Cabinet has asked Treasury to model these options, including changes to the Petroleum Resource Rent Tax (PRRT) and corporate income tax.
• A Greens-led Senate inquiry is examining gas export tax settings and has requested testimony from the CEOs of Santos, Woodside, Chevron, Shell, Inpex, and ConocoPhillips, as well as ambassadors from Malaysia, Singapore, South Korea, and Japan.
• The federal government announced a mandatory east coast gas reservation scheme, requiring LNG exporters to set aside 20% of their exports for the domestic market, effective July 2027. The policy aims to create a "modest oversupply" and put downward pressure on prices.

International Context and Expert Views

Energy experts and international bodies have noted that nations with expanded renewable energy, battery systems, and electric vehicles are better insulated from fossil fuel price volatility.

The conflict has raised prices for one-off LNG cargoes to Asia, with some reports stating cargoes sold for over double their previous price. The International Energy Agency (IEA) advised the Australian government against sudden alterations to corporate taxes, warning it could deter investment.

The conflict has also led to discussions about Australia's fuel security, with proposals from conservatives for increased domestic refining and storage being met with expert skepticism regarding economic viability and the time required for implementation.

Australia's Energy Transition and Grid Dynamics

Record Renewable Generation and Battery Storage

In the final quarter of 2025, renewable sources (including rooftop solar) supplied over 50% of electricity in the National Electricity Market (NEM) for the first time.

Grid-scale battery capacity saw significant growth, with 2 GW added in 2025—a 233% increase over 2024—making Australia the third-largest battery market globally. Home battery installations surged 260% year-on-year, reaching 268,675 units by the end of 2025.

A report from the Clean Energy Council stated that nine wind and solar projects added 2.1 GW of new capacity in Q4 2025, the highest volume commissioned in any single quarter.

Impact on Coal and Gas Generation

• Coal-fired generation declined to a record low quarterly average of 11,544 MW in Q4 2025.
• Gas-fired generation fell to its lowest level since 1999, decreasing by 27% compared to the same period in 2024.
• The Australian Energy Market Operator (AEMO) reported that in Q1 2026, grid-scale batteries more than doubled capacity year-on-year, shifting about three times more daytime solar energy to the evening peak, reducing the need for gas-fired generation.

Wholesale Electricity Prices

Wholesale power prices across the NEM averaged $50 per megawatt-hour (MWh) for Q4 2025, a 44% reduction year-on-year.

In Q1 2026, average wholesale electricity prices fell 12% compared to Q1 2025. The Australian Energy Regulator announced that default market offer (DMO) electricity prices would fall by up to 10% for some customers from July 1.

Grid Reliability and Transmission

During a record heatwave in Q1 2026, the grid maintained stability with minimal warnings from AEMO. Solar power provided over 60% of electricity during peak daylight hours.

The 900-kilometre Project EnergyConnect interconnector, linking NSW, Victoria, and South Australia, was completed at a cost of $4.1 billion. The project aims to facilitate renewable energy integration. AEMO reported needing to intervene at times to maintain system strength in Victoria and New South Wales when the number of synchronous generators fell below minimum levels.

Challenges to the Energy Transition

A report from the Grattan Institute stated that gas use in Australia is in structural decline across all sectors but that current decline rates are insufficient to meet climate targets.

Only 2.3 GW of new large-scale renewable generation reached financial close in 2025, a 46% reduction from 2024. The Clean Energy Council warned that investment in wind and solar is at a decade low.

A report from Climate Resource projects that global LNG markets will experience structural oversupply by 2030, which may put competitive pressure on high-cost suppliers like Australia. The report recommends planning for a decline in LNG exports as long-term contracts expire.

Policy and Political Debates

Opposition leader Angus Taylor announced a policy shift towards prioritizing coal power generation, stating a Coalition government would work to keep coal plants running. Several state governments have made arrangements to keep coal plants operating, such as Victoria with the Yallourn plant and NSW by underwriting the Eraring plant. The federal government has committed to an 82% renewable energy target by 2030.

Fuel Crisis and Behavioral Impact

Changes in Commuting and Travel

A Monash University study found that 45% of Australians altered their commuting and travel habits due to the fuel crisis.

The study reported a reduction in car dependency in metropolitan areas, with increased walking, cycling, and public transport use. In Victoria, public transport use rose after fares became free on March 31. 85% of financially concerned respondents changed their travel behavior compared to 56% of financially stable respondents.

State Government Public Transport Initiatives

• Victoria: Introduced free public transport for the month of April 2026, later extended to the end of May. From June 1, half-price fares will be implemented for the rest of 2026. The policy is estimated to cost $432 million.
• Tasmania: Announced free public transport from March 30 to July 1, 2026.
• Queensland: Maintained its existing 50-cent public transport fares.

Impacts and Reactions

The Victorian initiative led to reports of overcrowding on some services, including V/Line trains where seat bookings were suspended for long-distance routes.

Research from the University of Melbourne indicated that free public transport has a limited effect on reducing car usage, with factors like access, coverage, reliability, and travel time being more significant than price. Experts noted that free public transport primarily benefits those in inner-city areas with good service coverage and does not assist residents in city fringes, rural, or regional areas.

State Government Fiscal Positions

Victoria: Budget Surplus Amid Rising Debt

Victoria's 2026-27 state budget projects an operating surplus of $727 million for 2025-26, the first since the pandemic, and a $1 billion surplus for 2026-27.

Net debt is forecast to reach approximately $200 billion by 2029-30, with daily interest payments projected to rise to $32.3 million.

Spending allocations include:

• $1.04 billion for road repairs
• $432 million for public transport fare relief
• $750 million for a vehicle registration rebate
• $2.2 billion for disability inclusion in schools
• $1 billion for health

Key spending drivers are health expenses and interest payments. The budget includes pre-election spending and a review of the Sentencing Act. Opposition leader Jess Wilson criticized the operating surplus as not addressing the state's debt, while the treasurer stated the budget is "disciplined."

Other States and Territories

• Tasmania: Forecasts a net operating surplus of $192.8 million for 2027-28, its first since 2018-19.
• ACT: Has a widened budget deficit of $323 million for 2026-27, attributed to global economic pressures including the Middle East conflict. The government removed a health levy and abolished stamp duty for first home buyers.
• Queensland: Projects a $6.17 billion deficit for the current year, with deficits continuing until a forecast surplus in 2029-30. Net debt is expected to exceed $200 billion by 2028-29. The state faces a negative credit rating outlook from S&P.

Federal and Aggregate Context

Aggregate state and territory debt is expected to increase by 261% from $270.5 billion in 2019 to $976.9 billion by 2030, according to S&P Global data.

The federal deficit to the end of May was $10.9 billion, below the forecast $18.8 billion. Higher international LNG prices could add between $10 billion to $12 billion to Australia's federal budget in 2026-27, according to ANZ economists.

Key Reports and Analysis

Natural Gas Export Outlook

A report by Climate Resource, "The Last LNG Train Home," states that Australia's LNG export outlook is structurally constrained by declining global demand and an emerging oversupply as new capacity from the US and Qatar comes online by 2030. The report recommends that policymakers and investors stress-test LNG investments against demand-constrained scenarios and plan for economic diversification.

Gas Industry Taxation

A debate over gas industry taxation continues. Industry representatives report paying $21.9 billion in taxes and royalties in 2024-25.

Critics argue the current system, including the PRRT which raised $1.3 billion against $65 billion in export revenues, does not deliver adequate value.

Proponents of a 25% export tax estimate it could raise $17 billion annually. Former Treasury Secretary Ken Henry advocated for a 100% windfall profits tax on gas companies in a submission to a parliamentary inquiry.

Prime Minister Albanese confirmed the federal budget will not include a new tax on existing gas export contracts, citing the need to maintain Australia's reputation as a reliable energy supplier and secure fuel imports.
