What Erias Group does

ERIAS Group Pty Ltd is an Australian environmental and social impact assessment and management consultancy founded in 2012 and headquartered in Hawthorn (Melbourne), Victoria. The firm delivers life-of-project environmental and social performance services to enterprise clients in the energy, resources, and infrastructure sectors across Australia, Papua New Guinea, and the broader Asia-Pacific region, with four offices (Melbourne, Adelaide, Brisbane, Port Moresby) and a PNG-registered subsidiary.

The company's service portfolio spans twelve core capabilities anchored on Environmental and Social Impact Assessment (ESIA), with supporting lines in Permitting/Approvals/Compliance, Communities and Social Performance, Terrestrial and Aquatic Ecology, Marine Sciences, Surface and Groundwater Investigations, Climate Services, Decommissioning/Closure/Rehabilitation, Geospatial Services (including CASA-certified UAV surveying in Australia and PNG), Metocean Services, Ecological Risk Assessment, and Environmental and Social Management. Technical differentiators include IBERA Diplomate-certified ecotoxicology, deep-water oceanographic capability at depths exceeding 5,000 metres using ROVs, Niskin bottles, and BRUV, and demonstrable alignment with IFC Performance Standards, IPIECA guidelines, and the World Bank Environment and Sustainability Framework.

ERIAS generates revenue through project-based professional consulting engagements, typically multi-year and quote-priced, billed on a custom scope basis. The go-to-market is enterprise field sales into major oil and gas operators, mining companies, port and infrastructure developers, and government regulators, supported by direct client relationships, repeat engagements, conference presence, and referrals. Named enterprise clients include TotalEnergies, ExxonMobil, Santos, Oil Search, Moana Minerals, Larus Energy, Horizon Oil, Twinza Oil, PNX Metals, and TOLL Holdings, alongside the Northern Territory Government. The flagship engagement is the lead environmental consultancy role on the upstream Papua LNG Project since 2015, for which the project received its environment permit from PNG's CEPA in 2025.
