We outline how to write an effective Australian Public Service (APS) Expression of Interest (EOI) in 2025, including length, font, and structure guidelines. We also provide a full APS EOI written example, to help you understand exactly how to write your own.

APS EOI Length

The first step in preparing your APS EOI is understanding the length requirements. These will be outlined in the application kit provided with the job advertisement, and will take the form of either a word count (e.g. maximum of 600 words) or page count (e.g. maximum of two pages).

APS EOI Font and Presentation

Adhere to any specified presentation guidelines. If none are provided, use a standard font like Arial or Calibri, size 11 or 12. Keep formatting clean and professional. Avoid excessive margins or text that is too small, which can make your EOI harder to read. Aim for 550 words per page, to ensure your font is easy to read.

APS EOI Structure and Content

A strong APS EOI typically has three sections: an introductory paragraph, a body with specific examples, and a conclusion.

1. Opening Paragraph (50–100 words)

Begin with a brief summary of your relevant skills and experience. Explain why you’re interested in the role and how you can contribute meaningfully, referring to any specific departmental goals where appropriate. This section sets the tone and grabs the reader’s attention.

2. Middle Paragraphs: STAR Examples

The STAR method (Situation, Task, Action, Result) is essential for structuring your examples. Select 1–3 key achievements that align with the role’s requirements, combining multiple selection criteria into these examples. Focus on outcomes that demonstrate your ability to excel at the APS level you’re targeting.

3. Closing Paragraph (50–100 words)

Conclude by summarising your interest in the role and your capacity to contribute effectively. Reiterate your commitment to the values and goals of the department or agency.

Selecting Your Examples

To ensure your examples are relevant, ensure they suit the context of the role you are applying for. You will also need to align them with the APS Work Level Standards and Integrated Leadership System (ILS). This ensures your EOI demonstrates the level of responsibility and capability expected for the position.

APS EOI Full Written Example for an Accounting and Finance Officer (APS5)

Expression of Interest: Accounting and Finance Officer (APS5)

Dear [Hiring Manager’s Name],

I am excited to express my interest in the APS5 Accounting and Finance Officer position at [Department/Agency Name]. With over five years of experience in financial management and analysis within both public and private sectors, I bring a strong track record of delivering accurate financial reporting, streamlining processes, and driving compliance with relevant frameworks. My expertise in accounting software, budget preparation, and stakeholder collaboration positions me as a strong candidate to contribute effectively to the goals of [Department/Agency Name].

In my current role as a Senior Financial Analyst at [Company/Agency Name], I led a project to consolidate departmental budgets across multiple divisions. This involved liaising with cross-functional teams to identify discrepancies, resolve reporting issues, and establish consistent financial processes. I developed a new reporting template in consultation with stakeholders and introduced automated tools to streamline data entry and analysis. These changes resulted in a 25% reduction in reporting errors and increased efficiency in preparing quarterly budget updates.

Another key achievement was leading the implementation of compliance measures in line with updated APS financial policies. Following an audit that highlighted gaps in adherence, I was tasked with reviewing existing processes and creating a compliance framework. I conducted workshops with staff to raise awareness and developed easy-to-follow guidelines for meeting financial obligations. This resulted in a 30% improvement in audit outcomes, with the department meeting all compliance benchmarks in subsequent reviews.

Throughout my career, I have demonstrated the ability to manage competing priorities effectively while maintaining a high standard of professionalism. For instance, I successfully managed a $10 million operational budget while ensuring that financial reports met strict deadlines. I utilised my strong analytical skills to identify cost-saving opportunities, achieving a 10% budget surplus that was reinvested into departmental initiatives.

I am genuinely motivated by the opportunity to join [Department/Agency Name] and contribute to its vision of delivering transparent and innovative financial solutions to support public service excellence. I am inspired by the department’s role in ensuring fiscal accountability and enabling impactful programs for the Australian community. My professional values align closely with these goals, and I am eager to bring my analytical mindset, collaborative approach, and commitment to continuous improvement to the team. I would welcome the opportunity to discuss how my skills and experiences align with the requirements of the APS5 Accounting and Finance Officer role and how I can support [Department/Agency Name] in achieving its objectives.
