Western Environmental

What Western Environmental does

Western Environmental is a privately held Australian multidisciplinary environmental consultancy founded in 2011 and headquartered in West Perth, Western Australia. The firm delivers integrated environmental assessment, remediation, contaminated sites auditing, and advisory services across all Australian states, with selected international work in the United States. Its service portfolio spans fourteen practice areas including contamination assessment, PFAS treatment, contaminated sites auditing, environmental impact assessment, ecology, acid sulfate soils, asbestos, waste management, bushfire planning, ESG and climate change advisory, and compliance monitoring. Core clients are federal, state, and local government agencies, the Australian Department of Defence, airport operators, tier-one infrastructure contractors, developers, and industrial customers.

The firm combines consulting with turnkey remediation contracting, supported by proprietary and licensed technologies. Western Environmental holds a range of Intellectual Property licences to deploy novel PFAS treatment systems across Australasia, and its Senior Principal, Dr. David Reynolds, is a co-inventor of electrokinetic oxidation approaches for low-permeability source zone remediation and of electromigration for in-situ desalination. The firm employs accredited contaminated sites auditors in Western Australia and Queensland, a domain that is statutorily gated and supports the firm's independent review and expert witness work. The business is triple ISO certified (9001:2015, 14001:2015, 45001:2018) and has held Climate Active certification since 2020/21.

Revenue is generated through project-based professional services fees determined by scope, complexity, and client requirements, with anchor engagements running multiple years (e.g., estate-wide Defence PFAS programme, Metronet since 2017, Perth Airport advisory for over a decade). Go-to-market is direct enterprise field sales supported by government panel appointments and professional referrals; there are no reseller or marketplace channels. The firm has grown from a small WA-based operation to a national consultancy of 50+ professionals operating from six Australian offices, and is co-founder-led, with James Gibson serving as Managing Director since 2015 and remaining the principal executive. No institutional investors, parent entities, or funding rounds are disclosed, and growth to date has been organic.
