About Leighton Group Australia
Heritage, capability, and an unwavering commitment to the nation's most critical infrastructure.
Forged Through the Nation's Most Demanding Engineering Challenges

From those foundations, Leighton evolved into a full-service contractor capable of handling every phase of a major project. Today, our portfolio includes major healthcare precincts, defence and emergency infrastructure, residential communities, and critical national energy and transport projects.
With decades of combined experience and a national workforce, Leighton brings the depth of resources, technical expertise, and organisational resilience required to deliver the nation's most complex construction programmes.
