Australia's oil and gas exploration spending surged to a 10-year high of A$471 million ($329 million) in the March quarter, driven by Asian demand and technological advances that promise to ease a looming domestic supply shortage. Government data released in June confirmed the rebound, with spending projected to climb another 10% in 2026 to exceed $1 billion, according to Rystad Energy.
The uptick comes as last year's re-election of a second-term Labor government improved investment sentiment, though Canberra's regulatory uncertainty threatens to dampen the momentum. The Iran war has underscored the strategic urgency of developing new supply after years of sluggish investment left Australia facing an end-of-decade gas shortfall that could squeeze both domestic users and valuable LNG export revenues.
Three Gas-Rich Regions Lead the Charge
Most drilling activity is concentrated in the Otway Basin offshore western Victoria, the Beetaloo shale in the Northern Territory, and the Taroom Trough in Queensland. The Otway is the most established, benefiting from proximity to existing infrastructure. Exploration there has jumped as companies share rigs to cut costs, though results have been mixed. U.S. major ConocoPhillips drilled the country's first offshore wildcat wells in several years in late 2025. One well yielded gas, but a second found gas with higher-than-expected carbon dioxide content and lower volumes than predicted.
A ConocoPhillips spokesperson said the company is now working on an Offshore Project Proposal for a potential development to supply the domestic market. Some industry watchers suggest that steady Otway production could help ConocoPhillips meet domestic supply obligations tied to its Australia Pacific LNG export project. Amplitude Energy drilled a well deemed "non-commercial" in March and is reviewing whether to proceed with a follow-up. Jane Norman, Amplitude's CEO, told Reuters there's "a lot more activity in the Otway than we've seen in years."
Rick Wilkinson, CEO of advisory firm EnergyQuest, said offshore exploration remains promising but expensive. "We think it's a proven petroleum basin — it's got great rocks. The only issue is that CO2 sometimes shows up," he said.
American Shale Expertise Arrives in the Beetaloo
The Northern Territory government is aggressively pushing development of the Beetaloo, hoping to unlock an LNG-scale shale gas resource. It recently offered new acreage and co-funding to prospective explorers. Santos, Australia's No. 2 gas producer, is set to drill three appraisal wells there this year. In March, Japan's Inpex took a stake in a Beetaloo permit, potentially securing an onshore gas source for its Ichthys LNG plant in Darwin.
Drilling has benefited from the arrival of more powerful rigs used by companies like Tamboran Resources, capable of drilling long lateral wells with many fracking stages. Bryan Sheffield, co-founder of U.S. private equity firm Formentera Partners, which invested alongside Inpex and is working with Tamboran, told the Australian Energy Producers conference in May that "shale developers are the answer to the short supply in Australia." Sheffield, who ran Parsley Energy in the giant U.S. Permian shale, praised the regional government's welcoming stance. "They want Americans to come in," he said, adding that officials want U.S. service companies and flex rigs.
Wilkinson said the Texas experience is relevant. "They prove that they're able to do massive multi-stage fracks," he noted.
Bill Hare, founder of Climate Analytics, raised concerns that drilling the vast shale resources could be "very destructive" due to land impact and emissions when gas is burned. "Quite apart from the climate issue, the water demands are huge in an extremely arid region," Hare said.
Regulatory Confusion Threatens Investment
The government's plan to require LNG exporters to hold 20% of their gas for the Australian market may deter smaller players from investing more in exploration, because increased supply could keep a lid on domestic gas prices. Canberra has yet to spell out how the gas reservation will work.
Brett Woods, CEO of Beach Energy, the country's No. 3 oil and gas firm, told Reuters that "capital wants to find happy, comfortable places to invest, and at the moment the confusion is making it very hard to invest."
Despite regulatory uncertainty, explorers have been raising capital since late last year to drill for tight gas in the Taroom Trough. One of them, Omega Oil and Gas, found oil instead. UK major Shell recently shipped light oil to a local refinery after entering the region several years ago. The Taroom's liquids potential prompted the state government to fast-track development to boost Australia's limited domestic oil supply, though meaningful output is seen as years away.
Woods said the Taroom "offers real scale potential in terms of liquids production, which is desperately needed by Australia."
Why This Matters:
Australia's exploration surge represents a critical test of whether market forces and technological innovation can solve a domestic energy shortage without heavy-handed government intervention. The 10-year high in spending demonstrates that private capital responds to price signals and opportunity when regulatory frameworks provide clarity. Yet Canberra's unclear gas reservation policy threatens to undermine this momentum by creating uncertainty that deters investment. If the government allows the market to work—supported by territorial governments offering acreage and co-funding rather than mandates—Australia can secure both domestic supply and export revenues. The alternative is a supply crunch that forces rationing or imports, undermining energy security and economic competitiveness. The Beetaloo's potential to replicate American shale success depends on maintaining a welcoming investment climate and resisting the urge to micromanage outcomes through regulation.
