Foreign bidders face new barriers in Australian energy — is regulation the deal breaker?

Foreign investors eyeing Australia’s energy sector are discovering that the road to deal-making is no longer as smooth as it once was. The collapse of the Abu Dhabi–backed XRG Consortium’s proposed takeover of Santos Limited (ASX: STO) has underscored how regulatory risks, national interest scrutiny, and political sensitivities are reshaping the landscape for foreign capital. For one of Australia’s largest oil and gas producers, the sudden withdrawal of a multi-billion-dollar offer has not only rattled investors but has also sparked a broader debate about whether Australia is becoming a tougher market for global buyers of energy assets.

The Santos episode is far from an isolated event. Across both fossil fuel and renewable energy deals, foreign bidders are being asked to shoulder heavier obligations, provide stronger guarantees, and accept longer approval timelines. This raises the question of whether Australia, despite needing external capital to advance its LNG projects and renewable transition, is inadvertently building walls around its energy sector.

What legal frameworks and foreign investment rules are shaping ownership of Australian energy assets today?

At the heart of the issue lies the Foreign Acquisitions and Takeovers Act 1975 and the role of the Foreign Investment Review Board (FIRB). Every major foreign investment in critical industries such as oil, gas, and electricity is subject to review, with final decisions resting on whether a deal passes the “national interest” and “national security” tests. In practice, these terms allow considerable discretion. Transactions can be approved, delayed, approved with conditions, or rejected outright depending on the government’s assessment of risks to sovereignty, supply security, taxation, and public confidence.

Over the past two years, the system has become more stringent. Treasury has introduced new tax conditions, clearer guidance on deal structures, and a foreign investment portal designed to streamline—but also centralize—oversight. While most proposals are still approved, investors complain that the process has become slower and less predictable. Energy deals are especially exposed, as they touch on issues of climate policy, gas affordability, export revenues, and critical infrastructure.

Why did the collapse of the Santos takeover show how regulatory risks can derail even advanced energy M&A deals?

The withdrawal of the XRG Consortium from takeover talks with Santos offers a textbook example of how regulatory friction can derail even advanced negotiations. The consortium, which included Abu Dhabi National Oil Company through its XRG arm, Abu Dhabi Development Holding Company, and U.S. private equity firm Carlyle, had offered US$5.626 per share for Santos. After months of due diligence, the parties appeared close to signing a Scheme Implementation Agreement. But in the final stretch, disputes over regulatory risk allocation and domestic gas commitments caused the deal to collapse.

Santos’ board explained that it could not accept terms that left its shareholders carrying undue risk. Regulators were likely to impose strict conditions on foreign ownership of LNG and gas assets, particularly with respect to guaranteeing supply for Australian consumers. The consortium was unwilling to provide those commitments in a way that satisfied the board, and with the clock ticking on exclusivity deadlines, it walked away. The immediate aftermath saw Santos shares fall nearly 12 percent, a reflection of investor disappointment as the takeover premium evaporated.

How are domestic gas supply obligations turning into the biggest stumbling block for foreign bidders in Australia’s LNG sector?

One of the defining themes in Australian energy policy is the tension between lucrative LNG exports and the need to provide affordable domestic gas. Governments in both Canberra and state capitals have faced mounting pressure from households, manufacturers, and unions to prioritize domestic supply. This has made domestic gas obligations a frequent sticking point in M&A negotiations. Any foreign buyer of Australian gas assets is now expected to guarantee that local demand will be met before exports are prioritized.

For state-backed investors such as ADNOC, agreeing to long-term binding commitments on domestic supply can be commercially unattractive. But for regulators, those commitments are becoming non-negotiable. As the Santos case showed, when buyers and sellers cannot agree on this balance, even a multi-billion-dollar deal can collapse overnight.

What policy changes in 2024 and 2025 have made FIRB scrutiny tougher for global investors in Australian energy projects?

Over the last 18 months, Australia has signaled that it will treat foreign investment in energy as a matter of national security. FIRB has adopted stricter timelines for review, and Treasury has made it clear that deals involving critical infrastructure, state-owned entities, or sovereign wealth funds will face tougher questions. Beyond hydrocarbons, the renewable energy sector has also felt the chill. Several foreign-backed solar and wind projects have encountered delays because of land classification issues or concerns about the influence of state-owned investors.

A growing layer of conditions is also being added. Foreign acquirers are being asked to accept tax transparency clauses, stricter climate and environmental disclosures, and, in some cases, divestment requirements. In June 2025, Australia even initiated legal action against China-linked rare earth investors for breaching ownership rules, highlighting the government’s willingness to enforce penalties. These developments suggest that scrutiny is intensifying not only at the point of approval but also throughout the life of the investment.

How does Australia’s foreign investment regime compare with other resource-rich economies such as Canada and the United States?

Australia is not alone in tightening rules around foreign capital in energy. Canada has blocked Chinese investments in critical minerals, and the United States has used the Committee on Foreign Investment in the United States (CFIUS) to restrict acquisitions of energy infrastructure. What sets Australia apart, however, is the dual sensitivity of its energy sector: LNG exports form a massive revenue stream, but domestic gas affordability remains a politically charged issue. This means foreign investors face not just regulatory hurdles but also the possibility of populist pushback.

When compared to peers, Australia’s system remains relatively transparent, but the high level of discretion in applying the “national interest” test makes outcomes difficult to predict. This uncertainty is increasingly factored into valuations, with bidders demanding higher risk premiums or withdrawing altogether.

Why are valuations and deal pipelines in the oil, gas, and renewable sectors being reshaped by regulatory friction?

The immediate consequence of regulatory friction is fewer completed deals and lower valuations for Australian energy companies. Analysts noted that the takeover premium embedded in Santos’ share price since June vanished the moment the consortium withdrew. For other potential targets, this creates a valuation ceiling: unless buyers are confident they can navigate the approval process, they will hesitate to bid aggressively.

Private equity groups in particular are reconsidering their appetite for large-scale Australian LNG plays. Carlyle’s participation in the Santos bid showed that global funds remain interested, but its reluctance to absorb regulatory risks is likely to resonate across the sector. Meanwhile, sovereign investors such as ADNOC and Saudi Aramco may still pursue deals, but only if they can secure terms that protect their interests without binding them too tightly to local policy.

Could stricter oversight of foreign investment slow down Australia’s energy transition and renewable capital inflows?

Australia’s long-term climate and energy goals hinge on significant capital inflows. Building out renewable energy projects, transmission infrastructure, and gas peaking plants requires billions of dollars that domestic capital markets alone cannot supply. If foreign investors perceive Australia as a difficult jurisdiction, there is a risk that projects will be delayed or shelved. Industry groups have already warned that stricter screening rules could block “green capital” from flowing into solar and wind farms, undermining the speed of the energy transition.

At the same time, regulators argue that these barriers are necessary to ensure sovereignty, fair taxation, and public trust. In their view, investment that comes with no strings attached is not worth the long-term risks. The challenge for policymakers is to strike a balance that allows capital inflow without ceding control of critical resources.

What are the pathways for foreign investors to overcome Australia’s regulatory wall and still participate in the energy sector?

The Santos deal has shown that Australia’s regulatory wall is real and formidable. Yet it is not insurmountable. Investors willing to adapt their deal structures, form joint ventures with local partners, and commit to domestic supply obligations still have a path forward. The question is whether enough are prepared to accept these conditions in an environment where returns are already under pressure from commodity volatility and the costs of decarbonization.

For Santos, the collapse of the takeover may prove to be a turning point. The company will now need to prove its ability to deliver on the Barossa and Pikka projects, maintain its low-cost discipline, and reassure shareholders that long-term value can be created without foreign suitors. For the broader sector, the episode is a warning that foreign capital is not guaranteed, even in an era where global players are hungry for LNG exposure.

Australia’s energy ambitions—whether in LNG exports or renewable buildout—will ultimately depend on how effectively it manages this balancing act. For now, the regulatory wall stands high, and investors must decide if they are willing to climb it.
