Western Australia Tenders

Western Australia's resource-driven economy generates substantial government procurement in mining services, infrastructure, and environmental management. Tenders WA is the centralised portal, with major opportunities from the Department of Finance, Main Roads WA, Water Corporation, and regional development commissions across the state.

WA Government procurement thresholds require open tenders for goods and services valued above $250,000, and for construction works above $250,000. Between $50,000 and $250,000, agencies must seek at least three written quotations. The Department of Finance oversees procurement policy and maintains a range of common-use arrangements (CUAs) that pre-qualify suppliers for frequently purchased goods and services. Getting onto a relevant CUA can provide a steady flow of work without needing to compete for individual tenders.

To register on Tenders WA, visit tenders.wa.gov.au and create a free supplier account. You will need your ABN, contact details, and information about your products or services. The portal allows you to set up watchlists and email notifications based on category codes, agency names, or keywords. Registration also gives you access to contract award information and forward procurement plans published by agencies.

Western Australia's Buy Local Policy is one of the most supplier-friendly policies in the country. It provides a price preference of up to 20% for regional businesses when evaluating tenders — 10% for businesses based in the Perth metropolitan area and up to 20% for businesses in regional WA. The WA Government also maintains an Aboriginal Procurement Policy targeting 3% of contracts awarded to Aboriginal businesses. The Western Australian Industry Participation Strategy encourages maximum local industry involvement in government projects, particularly for major resource and infrastructure developments.

The WA budget is typically delivered in May, with peak procurement activity from July through November as agencies begin spending new allocations. The resources sector cycle also influences government procurement patterns, as royalty revenues affect state spending capacity. Construction and infrastructure tenders maintain relatively steady volumes year-round due to long-term project commitments, though the extreme heat in northern WA can influence the timing of outdoor works in the Kimberley and Pilbara regions.

Major project pipelines driving tender opportunities include METRONET (Perth's rail expansion program), Westport (the new Kwinana container port), and significant road upgrades across the metropolitan and regional network. The state's renewable energy transition, including green hydrogen projects in the Pilbara and large-scale wind and solar developments, is creating a new wave of procurement. WA's hospital program, including the Women and Babies Hospital relocation, generates substantial health infrastructure tenders.

New suppliers should register on Tenders WA and investigate relevant common-use arrangements, as these provide an efficient path to government work. Understanding the Buy Local Policy is essential — if you are a WA-based business, make sure your tender responses clearly state your local presence and the policy preference you are entitled to. For regional opportunities, consider establishing a regional office or partnering with a regional business to maximise your price preference advantage.
