Austral Construction Pty Ltd.

What Austral Construction Pty Ltd. does

Austral Construction Pty Ltd is a specialist Australian marine, civil, and mining construction contractor founded in 1996 and headquartered in Perth, Western Australia. The company operates as a wholly-owned subsidiary of Keller Group plc, a London-listed global geotechnical engineering group. Austral delivers four core service lines — civil and structural works, land-based piling, marine construction, and rail renewals — to resource majors (Rio Tinto, BHP, Roy Hill, Mineral Resources, Fortescue), port authorities (Pilbara Ports Authority, Port of Melbourne), government agencies (Public Transport Authority of WA, Transport for NSW), and tier-one head contractors (McConnell Dowell, Fulton Hogan, Lucas Total Contract Solutions). Work is secured through competitive tendering and long-term framework agreements, with a project-based delivery model supported by FIFO operations in the Pilbara.

The company's competitive position rests on a substantial owned fleet of specialized equipment: five self-elevating modular platform (SEMP) jack-up barges ranging from 80t to 500t capacity, the modified Sennebogen 6100 HD-XLR piling rig (described as the largest driven-piling rig in the southern hemisphere with a 60m mast), hydro and vibration hammers, crawler cranes, and a Komatsu civil fleet. Austral owns the proprietary ROTOPILE method for extracting driven steel tubular piles that cannot be removed by conventional means, and has demonstrated Australia's longest single-length raked piles (46m at Swanson Dock) and tolerances of 2mm per metre (Onslow Iron). The firm maintains ISO 9001, ISO 14001, and ISO 45001 certifications (all held since 2000), Federal Safety Accreditation, and a structured Engineering Graduate Program in partnership with Engineers Australia.

Revenue is generated primarily through professional services contracting (construction works delivered on a project basis) supplemented by specialist plant hire when internal fleet capacity is available. Pricing is project-specific and quote-based via competitive tenders. The company operates offices in Perth, Melbourne (relocating to WA in 2024), Sydney, Brisbane, and Adelaide, with warehouse and yard facilities in Canning Vale, Dandenong, and Wedgefield (Port Hedland). Austral Construction is privately held with no publicly disclosed revenue; cumulative contract value with anchor clients Rio Tinto and BHP exceeds A$750m since 2005 and 2013 respectively.

Core offering

Austral Construction is a specialist engineering contractor delivering marine piling, civil and structural construction, and rail renewal services to mining, port, and infrastructure clients across Australia. The company self-performs projects using its own extensive fleet of jack-up barges, piling rigs, cranes, and civil construction plant, enabling it to operate in remote locations such as Western Australia's Pilbara region.

Product overview

Austral Construction is an established engineering contractor providing specialized services to the mining and infrastructure sectors. The company operates as part of Keller Group plc, a global leader in geotechnical engineering. Its core service offerings are organized into four main capability areas: Civil and Structural, Land-Based Piling, Marine Construction, and Rail Renewals (Civil). These are supported by specialized plant and equipment services, with Austral maintaining and operating an extensive fleet of marine vessels (jack-up barges, floating barges, support vessels), piling equipment (hydro hammers, vibration hammers, piling rigs), cranes (crawler and mobile), and civil construction equipment (excavators, loaders, graders, trucks). The company also operates a Graduate Program for workforce development. Together, these services enable self-performance of large-scale construction projects while reducing construction and plant risk.
