An Australian Expression of Interest (EOI) is a formal document submitted by a company or individual to a government agency, local council, or corporate buyer to signal their interest in and capability to participate in a procurement process, tender, or standing offer arrangement. An EOI is typically the first step in a multi-stage procurement process: the buyer uses EOI responses to shortlist capable suppliers before issuing a full Request for Tender (RFT) or Request for Proposal (RFP) to a smaller pool of qualified respondents.

In Australian government procurement, EOIs are used across all levels of government — federal, state, and local — as a market engagement tool. At the federal level, EOIs are conducted in accordance with the Commonwealth Procurement Rules 2023 (made under the Public Governance, Performance and Accountability Act 2013 (Cth)). Each state and territory has its own equivalent procurement framework: for example, NSW Government Procurement, the Victorian Government Purchasing Board (VGPB), Queensland Government Procurement, and the Western Australian State Supply Commission. These frameworks all recognise the EOI as a legitimate mechanism for testing the market and building supplier panels.

A well-prepared EOI response demonstrates to the buyer that your organisation has the experience, capability, financial standing, and governance frameworks to successfully deliver the required services. Unlike a full tender response, an EOI does not typically require detailed methodology or a comprehensive priced schedule — instead, it focuses on your organisation's track record, core competencies, key personnel, accreditations, and capacity to respond. EOIs are also used in the private sector for major procurement decisions, commercial property transactions, and infrastructure development projects.

An Australian EOI must include the respondent's ABN and ACN, confirm GST registration status, and address any specific capability or experience criteria set out in the buyer's EOI documentation. A professional, well-structured EOI that clearly addresses all evaluation criteria, provides credible evidence of past performance, and presents the organisation compellingly will maximise the likelihood of progressing to the shortlisted RFT stage.

You should prepare an Expression of Interest whenever a government agency, local council, university, hospital, or major corporate buyer invites suppliers to express interest in an upcoming procurement opportunity before a formal tender is issued. The following are the most common circumstances in which an Australian EOI is required.

Government Procurement Panels and Standing Offers — Many Australian government agencies establish procurement panels or standing offer arrangements through an EOI process. Successful respondents are registered on the panel and can be approached directly for work without a further open tender. Examples include federal government panels under the Digital Transformation Agency's Digital Marketplace, state government procurement panels for professional services, ICT, construction, and facilities management, and local government contractor panels.

Pre-Qualification Registers — State government building and construction agencies (such as the NSW Department of Public Works, Queensland Department of Energy and Public Works, and the Victorian Department of Treasury and Finance) maintain prequalification registers for contractors and consultants. Registration typically requires an EOI or application demonstrating financial capacity, relevant experience, and quality management systems.

Infrastructure and Capital Works Projects — Major infrastructure projects often begin with an EOI to identify interested and capable contractors before a Design-and-Construct or Alliance contract tender is issued. Examples include large road, rail, and building projects.

Not-for-Profit and Community Sector Grants — State and federal government funding programs in the community, aged care, disability services (NDIS), and early childhood sectors often require an EOI from potential service providers before a full funding application or grant agreement process is commenced.

Corporate Supplier Shortlisting — Large private sector organisations in banking, resources, retail, and healthcare regularly use EOIs to shortlist new suppliers for professional services, technology, logistics, and facilities management contracts.

A professional Australian Expression of Interest should contain the following key elements to be competitive in government and corporate procurement processes.

Company Identification and Legal Details — Every Australian EOI must clearly state the respondent's full legal name, ABN, and ACN. These identifiers are required for the buyer's supplier registration and due diligence processes. The registered address and primary business contact (name, title, phone, email, and website) must also be included. Confirm your GST registration status, as government buyers require GST-registered suppliers for most contracts.

Company Overview and Track Record — Provide a concise overview of your organisation's history, size (number of employees), geographic coverage, and principal service lines. Include the year your business was established, as longevity is often used as a proxy for financial stability and operational maturity in government evaluation processes.

Relevant Experience and Past Projects — This is typically the most heavily weighted section in government EOI evaluations. List your most relevant past projects with the client name, scope of work, contract value (if you are permitted to disclose it), and year of completion. Where possible, select projects that demonstrate experience with the specific type of buyer (government, healthcare, education), the specific service type (construction, ICT, facilities management), and the contract scale required. Government buyers are particularly interested in evidence of successful delivery on contracts of comparable size and complexity.

Core Capabilities and Proposed Approach — Describe your organisation's key capability areas relevant to the procurement and provide a high-level outline of how you would approach the engagement. This section should demonstrate that you understand the buyer's requirements and have a credible, structured method for delivering them.

Accreditations, Certifications, and Licences — List all relevant quality, safety, environmental, and industry certifications (such as ISO 9001, ISO 14001, OHSAS 18001 or AS 4801), industry licences (such as building licences, electrical contractor licences, or security licences), and government prequalification registrations.

Referees — Provide at least two referees from relevant past clients, including their name, organisation, role, and contact details. Government buyers will typically contact referees as part of the evaluation process.

Insurance Coverage — Confirm your current insurance coverage for public liability, professional indemnity, and workers compensation. State the policy limit for each type and offer to provide certificates of currency on request.

Declaration of Accuracy — Include a declaration signed by an authorised officer confirming the accuracy and completeness of the information provided, the organisation's legal capacity and financial standing, and its compliance with applicable laws including the Privacy Act 1988 (Cth), the Work Health and Safety Act 2011 (Cth), and the Modern Slavery Act 2018 (Cth) (if applicable).
