Certifications
The Challenge
A 280 km transmission corridor passing through active native title claims, critical habitat for four listed threatened species, and across country held by three separate Traditional Custodian groups - each with distinct consultation requirements.
Our Solution
Le Gardenz embedded a dedicated environmental and cultural heritage team 12 months before construction, completing all flora and fauna surveys, heritage assessments, and Traditional Owner negotiations ahead of the contractor's mobilisation. This front-loaded approach prevented any construction programme impacts from environmental approvals.
Scope of Works
Flora and fauna surveys - 280 km corridor
Cultural heritage assessment - three native title areas
Construction-phase environmental monitoring
ESC installation and compliance across 8 work fronts
68 ha offset revegetation and establishment
End-of-construction rehabilitation and audit

Zero non-compliances issued by DWER or EPA
- -
All threatened flora translocation targets met within growing season
- -
Cultural heritage clearance completed on time across all fronts
- -
68 ha of offset revegetation established and certified
