Oil & Gas

Decisions that hold up under time, pressure and scrutiny

Overview

Oil and gas projects are long-term bets. One development decision can lock in costs, risks or disputes for decades. When you are dealing with shifting regulation, capital-intensive infrastructure and counterparties who think in decades, you need clarity early and legal judgement that lasts.

We are a national, full-service oil and gas team with experience across upstream, midstream and downstream. Our partners have advised on high-stakes matters from first development and approvals through to M&A, operations, price reviews and decommissioning.

We were at the forefront of advising through the period when three of Australia’s LNG megaprojects were developed simultaneously, in a high pressure and high stakes environment and with tight timelines and commercial scrutiny from every direction. That experience continues to shape how we advise today.

Why clients trust us

We think in decades, not just deals

We show you how today’s approvals, deal structures and risk allocations play out over time. One workable consent is worth more than thirty piecemeal modifications.

We navigate tough regulatory and policy environments

We help clients respond to market interventions, shifting regulatory frameworks and political pressure, with strategies built to hold up when the goalposts move.

Negotiation strategies that reflect real leverage

We calibrate how hard to push and when to hold, protecting long-term relationships while still securing what matters most.

Market intelligence that saves time

We know where leverage actually exists and what counterparties will accept. That stops you spending resources on positions that will never land.

Execution that holds up under pressure

We identify issues early, produce clean documents and keep your credibility intact throughout negotiations and regulator engagement.

Integrated advice across the value chain

Upstream. Midstream. Downstream. Decommissioning. One team, one view, with insight into how each part of the operation affects the rest.

What you can count on

Regulatory strategy that scales over time

Approvals that work in practice, not just on paper, even as regulation changes.

Support through complex policy environments

Advice that anticipates shifts in gas codes, ESG expectations and regulatory oversight.

Contracts designed to last

Agreements built to handle pressure, complexity and decades of interaction.

Alignment from development to decommissioning

Legal advice that connects early decisions to long-term obligations and costs.

Sector fluency, not legal guesswork

We understand how oil and gas players think, operate and negotiate.

Judgement shaped by real exposure

Our partners have advised on Australia’s most complex and commercially significant oil and gas projects, and continue to do so today.
