Energy, Resources & Infrastructure

Achieving world firsts in energy, resources and infrastructure

Are you looking for an international legal team in energy, resources and infrastructure that can support you every step of the way?  At Mallesons we offer you exactly that.

The Mallesons team act on the energy and resources projects that the world takes notice of – across each and every stage of a project’s lifecycle, remaining nimble enough to adapt to market changes, yet still leading the way on the largest and most complex transactions.

Mining giants, infrastructure proponents, oil and gas pioneers, power providers and renewables innovators lean on the Mallesons team to support their leap into Australia and beyond.  Our legal advice helps clients deliver firsts, like the world’s first coal seam gas (CSG) to liquefied natural gas (LNG) project, the first Tesla Megapack big battery technology in Australia and the first sustainability-linked infrastructure financing with an interest rate directly linked to an emissions target.  We also pride ourselves on having the bench strength to execute nationally significant ‘megadeals’, like the mining industry’s biggest ever deal (the Glencore/Xstrata merger) and the winning bid to acquire a majority stake in Sydney’s WestConnex – the largest road infrastructure project in Australia.

Supporting clients end-to-end

From day one, we will help you navigate the areas of law underpinning transactions in the  energy, resources and infrastructure sectors. If you need approvals to get a project under development, assistance with project structuring or finance, we can help. Our end-to-end experience means we are equipped to work with regulators, policymakers and government authorities, as well as sponsors, banks and other proponents on domestic and international projects.
