Brefni Information

Brefni delivers sustainable civil infrastructure across Australia's public and private sectors - on time, on budget, and built to last. We partner with government agencies, tier-one contractors, and private clients to deliver complex, safety-critical projects across Transport, Water, Defence, Energy, and Industrial sectors. Our head office is based in Sydney - with offices in Wagga and Queensland. Our team brings the technical depth and accountability of a major contractor with the agility of a specialist delivery partner. Our work is guided by five values: safety, integrity, discipline, agility, and collaboration. These aren't words on a wall - they shape how we plan, how we build, and how we show up for our clients and communities every day. From major road and rail corridors to water treatment facilities, Defence assets, and industrial infrastructure, Brefni takes on the projects that matter and delivers them with precision and pride. Infrastructure that Matters.
