Top Construction Companies in Australia

Construction is one of Australia’s largest industries — a sector worth hundreds of billions of dollars a year and close to a tenth of national economic activity, spanning everything from high-rise apartments and hospitals to the rail tunnels reshaping Sydney and Melbourne. The companies behind that work range from ASX-listed services and property groups to privately owned family builders that have worked across the country for generations.

This post ranks the largest construction companies in Australia by their most recent reported annual revenue in Australian dollars, drawn from company annual reports and IBISWorld estimates for FY2024 and FY2025. That is a change from earlier versions of this list, which ranked firms by BCI Construction League “total project value.” BCI’s current league is subscriber-only with no public figures, so we moved to reported revenue — a cleaner, verifiable basis, though it measures a different thing. Project value counts the worth of the jobs a firm is building; reported revenue is what the business actually booked. Ranks shifted as a result.

The top construction companies in Australia

Here are the largest construction companies operating in Australia, ranked by reported annual revenue (AUD).

Source: company annual reports + IBISWorld (FY2024/FY2025). Ranking basis = reported annual revenue (AUD).

Downer EDI

Headquarters: Sydney, New South Wales Reported revenue: A$10,566 million (FY25, pro forma) — rank #1

Downer is a leading provider of integrated services across Australia and New Zealand, and the largest company on this list by reported revenue. It is worth saying plainly that Downer is not a general building contractor in the way most firms below it are — it designs, builds, and then maintains essential infrastructure, and much of its revenue comes from long-run operations and maintenance rather than one-off construction. The group employs roughly 26,000 people across more than 500 locations and is listed on both the ASX and NZX.

Downer’s services include:

• road, rail, and transport infrastructure delivery and maintenance
• power, energy, and utilities infrastructure
• water and wastewater treatment
• telecommunications infrastructure
• facilities management and social infrastructure

The company has extensive experience servicing the following sectors:

• transport (roads, rail, ports, and airports)
• energy and utilities
• water
• defence and government
• health, education, and social housing

Downer maintains around 50,000 kilometres of road network and serves more than 14 million water and wastewater customers, a scale that reflects how much of its work is ongoing service delivery rather than pure construction. It remains one of the largest private-sector employers in the region.

CIMIC Group (CPB Contractors)

Headquarters: North Sydney, New South Wales Reported revenue: A$7,740 million (2024, engineering-and-construction segment) — rank #2

CIMIC Group is one of the largest construction and infrastructure organisations in Australia, and its principal contracting business is CPB Contractors, which has been delivering for clients and communities for more than 90 years. The revenue figure here is CIMIC’s engineering-and-construction segment, which owns both CPB Contractors and the services business UGL. CPB operates across Australia, New Zealand, and Papua New Guinea.

CPB’s services include:

The company is owned by China Communications Construction Company (CCCC). As of 2025 it employed 5,753 direct staff and had about A$25.9 billion of work under contract across 78 active projects.

Lendlease

Headquarters: Sydney, New South Wales Reported revenue: A$6,214 million (FY25) — rank #4

Lendlease is a real estate company with three deep capabilities — investments, development, and construction — which is the honest way to read its position on this list. Its revenue is not purely contracting; it spans development profit, funds management, and building work. Founded in 1958, Lendlease has spent more than 65 years shaping some of Australia’s best-known urban precincts.

Lendlease’s services include:

As a diversified property group, its construction arm is only one part of a broader real-estate business.

Multiplex

Headquarters: Sydney, New South Wales Reported revenue: A$5,700 million (2024, global figure) — rank #5

Multiplex was established in Australia in 1962 and has delivered over 1,150 projects worldwide, with a combined value above US$130 billion. It is one of the country’s most recognisable builders of complex, large-scale projects. The A$5,700M shown is Multiplex’s global 2025 revenue of about US$3.8 billion, spanning Australia, the UK, and Canada; the group does not publish an Australia-only revenue line. Multiplex is owned by Brookfield; in June 2026 Brookfield agreed to sell the business to Japan’s Obayashi Group, with close anticipated in Q4 2026.

Hutchinson Builders

Headquarters: Brisbane, Queensland Reported revenue: A$3,500 million (FY24, estimated) — rank #6

Hutchinson Builders — “Hutchies” — is one of Australia’s largest privately owned construction companies and is 100% Australian-owned, founded in 1912 and still run in the tradition of a family business. Because it is private, its revenue is an estimate rather than an audited disclosure. The Brisbane-headquartered builder works nationally across an unusually broad range of project types, from apartment towers to industrial facilities.

Hutchinson’s services include:

• commercial and residential building
• industrial and warehouse construction
• fitout and refurbishment
• civil works
• retirement and community facilities

The company has extensive experience servicing the following sectors:

• residential and mixed-use

Built

Headquarters: Sydney, New South Wales Reported revenue: A$3,105 million (FY25, IBISWorld estimate) — rank #7

Built is a 100% Australian-owned, digital-first contractor that has grown into one of the largest private construction businesses in the country. Its revenue figure here is an IBISWorld estimate.

Mirvac Group

Headquarters: Sydney, New South Wales Reported revenue: A$2,735 million (FY25) — rank #8

Mirvac was established in 1972 and is an ASX-listed creator and curator of urban places, with in-house design, development, and construction teams. Like Lendlease, it belongs on this list as a diversified property group rather than a pure contractor — its revenue spans residential development, commercial and industrial assets, retail, build-to-rent, and funds management — well beyond building work alone.

Mirvac’s services include:

• residential development and construction
• commercial and industrial development
• retail development and management
• build-to-rent housing
• funds and asset management

The company has extensive experience servicing the following sectors:

• residential communities and apartments
