Expression of Interest (EOI) Writing Services Australia

An Expression of Interest (EOI) is often the first step in a multi-stage procurement process — and a poorly written EOI means you won’t make it to the next stage. At Public Sector Contracts, we write EOI submissions that clearly articulate your capability, your experience, and your fit for the opportunity — giving you the best possible chance of being shortlisted.


EOIs require a different approach to full tenders — they need to be concise, targeted, and focused on the evaluation criteria that matter most at the shortlisting stage. We understand how to make a strong first impression in a limited word count.


We offer both standalone EOI writing and a combined EOI-to-tender package for multi-stage procurement processes, ensuring strategic consistency if you’re invited to submit a full tender.

Shortlisting Strategy

We write EOIs with the shortlisting criteria in mind — focusing on the evidence and capabilities most likely to secure your place in the next stage.

Concise and Compelling

EOIs are usually subject to strict word or page limits. We write tightly, making every word count without sacrificing clarity or persuasiveness.

Stage-One to Stage-Two Continuity

For multi-stage procurement processes, we plan your EOI response with the full tender in mind — ensuring consistency and strategic alignment across both stages.

Frequently Asked Questions

What is an Expression of Interest (EOI) in government procurement?

An EOI is a formal document submitted to a government agency or organisation to indicate your interest in a procurement opportunity and demonstrate your capability to deliver. EOIs are commonly used as the first stage of a multi-stage procurement process, with shortlisted respondents then invited to submit a full tender or proposal.

An EOI is typically shorter and less detailed than a full tender — it’s designed to assess whether a supplier has the basic capability and interest to proceed. A tender is a full, evaluated submission in response to a Request for Tender (RFT). EOIs are often the gateway to being invited to tender.

A strong EOI typically includes a brief overview of your business, evidence of relevant experience and past performance, an outline of your proposed approach, and confirmation that you meet any mandatory eligibility criteria — all presented as concisely as the word limit allows.

EOI length is usually set by the issuing agency, often somewhere between 2 and 10 pages depending on the opportunity. We always work within the stated limit, since exceeding it can result in a non-compliant submission.

Yes — because EOIs are shorter than full tenders, we can often turn around a quality response relatively quickly, even with limited notice. Get in touch as soon as you see the opportunity and we’ll assess what’s achievable.
