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.

Located on Perth’s northern coastline, Ocean Reef Marina is transforming a former boat harbour into a vibrant, world-class coastal destination. Upon completion, the development aims to deliver more than 1,000 new homes, 12,000 square metres of retail and commercial space, and over five hectares of public amenities – including Perth’s first metropolitan coastal pool and a family-friendly beach.

Sustainability has been embedded in the development from the outset, with innovative measures aimed at reducing environmental impact while enhancing community outcomes. A standout initiative is the integration of a renewable energy microgrid, operated by Ocean Reef Renewable Energy (a Zenith Energy company). This system will reduce energy bills by up to 30 per cent for future residents and businesses while supporting greater energy resilience.

Smart city technologies and sustainable construction practices further reinforce the development’s sustainability credentials. . More than 80 per cent of construction waste is being diverted from landfill, with recycled materials used in roads, car parks, drainage and more. The project also prioritises native landscaping and urban greening to support local biodiversity and improve urban cooling.

The EnviroDevelopment certification, independently awarded by the Urban Development Institute of Australia, recognises excellence in sustainable design and construction. In achieving full certification across all six categories affirms DevelopmentWA’s commitment to delivering leading-edge projects that protect the environment, support communities, and set new standards for sustainable urban development.

“We’re incredibly proud to be delivering the first marina in Australia to achieve full EnviroDevelopment certification. This milestone reflects our focus on innovation and long-term sustainability — not just for the environment, but for the people who will live, work and visit Ocean Reef Marina,” Dean Mudford, DevelopmentWA CEO.

In late 2026, key public amenity is anticipated to open to the public, including the protected family beach and beach playground. Ocean Reef Marina is on track to become a thriving, sustainable hub for tourism, recreation and coastal living.

The development will activate the north-western entry into Latitude 32 and combined with the Flinders Precinct, will ensure an ongoing supply of industrial opportunities in Perth’s premier industrial corridor.

Ecosystem: Orion manages all stormwater on-site, preventing any discharge into other catchments or wetlands. Estate Design Guidelines ensures the prevention of pollutants from leaching into the water table and conservation areas. Native plant species are integrated into streetscapes to reduce the urban heat island effect and maintain biodiversity corridors. Seedlings propagated from seeds collected from the local area have been used in the landscaping,

Waste: Orion reused vegetation cleared from the land as mulch on-site and repurposed clearing material from the quarry area. A comprehensive recycling system was placed for civil works materials, including metal, PVC, concrete, and concrete with steel. Furthermore, concrete is recycled into base course pavement products. New proponents are required to incorporate waste management into their designs.

Energy: Energy efficiency is achieved by mandating efficient building orientation, external shading devices, skylights and Solar PV arrays through the Estate Design Guidelines. The measures outlined in the Estate Design Guidelines lead to a 20% total greenhouse gas emissions reduction over BAU.

Materials: Roads within the estate incorporated site-won limestone subbase, recycled road base, and blending of recycled concrete and asphalt. Shell waste and topsoil material are blended and reused, and specified piping is procured from environmentally responsible sources.

Water: Orion includes waterwise landscaping, the use of bio-retention basins, and the installation of rainwater tanks for toilet flushing and irrigation systems for private lots. Water-efficient fixtures and appliances are mandated.

Community: Orion Industrial Park will generate job opportunities and support local businesses. The drainage basin has been redesigned to incorporate public amenities for local users.

OneOneFive Hamilton Hill has achieved UDIA’s EnviroDevelopment Excellence certification for its ambition and achievement across a range of sustainability initiatives. The gas-free and environmentally sensitive development also minimises waste and reduces water and energy consumption, while retaining the site’s landform, mature trees and biodiversity. Climate-responsive planning mitigates and monitors urban heat through careful material selection, shading, and water sensitive urban design initiatives designed to hydrate and cool the landscape. The development includes two hectares of high quality, inclusive public open space that is connected via retained trees, and features nature play areas, kick-about space, remnant bushland, and waterwise landscaping. A 30% tree canopy target supports shaded, walkable streets and cooler neighbourhoods. The project honours the site’s educational and Indigenous heritage through interpretive design, material reuse, street naming, and public art. Community engagement and connection with surrounding residents has also shaped project delivery, including a pocket park co-design process and a waterwise verge upgrade initiative.

OneOneFive focuses on industry advancement by demonstrating best practice resource recovery, climate resilient and water sensitive urban design, and built form outcomes. The built form responds to physical site requirements, experiments with compact lots, and promotes timber framed construction. Design Guidelines and a Waterwise Incentive Package support residents and their builders to exceed minimum regulatory sustainability standards.

OneOneFive also serves as a living laboratory for applied research to verify sustainable design. The Waterwise Exemplar project trials waterwise initiatives, documents implementation, monitors household water use and via sensors and data visualisation and communicates learnings via presentations and site tours to assist with mainstreaming. The Smart Neighbourhood Waterwise Performance Monitoring and Evaluation project includes microclimate monitoring and modelling to understand how specific materials, vegetation, density and urban layout impact urban heat. OneOneFive is also the subject for research into circular economy construction practices.

Insights from these initiatives are informing future sustainable infill developments across Perth, advancing the city’s transition toward a cooler, more resource-efficient, and resilient urban future.

The Alkimos Beach development, a partnership between DevelopmentWA and Lendlease, is one of the biggest coastal developments in Perth’s northern growth corridor in more than 50 years.

In line with the development partners’ goals to create carbon neutral ‘all-electric’ communities, the development of Alkimos Beach is taking a long-term view to ensure the commercial, retail, employment and lifelong learning opportunities created today are relevant and sustainable in the future. Alkimos Beach is positioned as a leader in sustainable living through a range of initiatives that allow residents to minimise their energy and water consumption, thus strengthening the community’s resilience today and in the future.

The built form outcomes have a strong focus on achieving significant energy and water efficiencies for residential households, with financial savings for householders as a result. To achieve all-electric living, all homes at Alkimos Beach are required to install a solar PV system, and a solar electric or pump water heating system. Installation of induction cooktops are also incentivised.

Retention of existing key landscape features has been a major driver in the design of the beach development and involves creating landscape corridors connecting urban areas with the coast and areas of retained open space and dunes.

Implementing best practice for waste management and using environmentally responsible materials in construction ensures the built component of Alkimos Beach is a leading example of sustainable development.

There is also a very strong commitment by the development team to expand community knowledge of how to create and live a more healthy and sustainable life.
