Sustainability is embedded throughout the estate via its alignment with EnviroDevelopment certification, supported by comprehensive Design Guidelines covering climate‑responsive design, energy efficiency, renewable energy, waterwise irrigation, and waste reduction. Mandatory requirements include WELS‑rated water‑efficient fixtures, Department of Health‑approved Secondary Treatment Wastewater Systems, and integrated waterwise irrigation delivering 100% reuse of onsite treated wastewater for landscaping and tree establishment. This approach is particularly innovative given the region’s arid desert climate, absence of groundwater, and reliance on scheme water, which is pumped 600km from the Perth Hills.
Energy initiatives further strengthen environmental performance, mandating a minimum 6.6kW solar PV (photovoltaic) system for every development, with best‑practice recommendations for expanded PV and battery storage. Independent modelling shows this combination can reduce emissions by up to 19%, and further reductions are achieved through design measures such as light‑coloured roofs, high‑performance glazing and effective shading.
Environmental protection measures ensure the estate delivers an ecological net gain, including retention of Priority 1 flora, revegetation using local seed mixes, fauna‑sensitive clearing practices, and topsoil conservation. Waste management requirements ensure at least 80% of construction and land‑clearing material is reused or recycled, including vegetative debris processed onsite into mulch to support landscaping.
The project’s sustainability focus is strengthened by a community education program, using design guidelines, factsheets, and interpretive materials to communicate waste hierarchy principles, water and energy efficiency, and the use of environmentally responsible materials.
Extensive engagement with State Government agencies, the City of Kalgoorlie‑Boulder, industry stakeholders and local First Nations representatives has informed planning, ensuring the estate responds to market needs, cultural values and environmental sensitivities. “Yilkari Industrial Park demonstrates DevelopmentWA’s commitment to delivering industrial land that is resilient, efficient and environmentally responsible. EnviroDevelopment certification provides a clear and trusted framework that ensures sustainability remains central to every stage of the project,” said DevelopmentWA Development Director Breanne Chrimes.
