Mr Andrew Wilson
Office Manager
Brisbane Corporate Solutions
Level 6, 180 Queen Street
Brisbane, QLD 4000
Dear Mr Wilson,
When I saw that Brisbane Corporate Solutions is seeking an Office Assistant to support your expanding team of 40+ staff, I knew this was exactly the opportunity I’ve been preparing for. As someone who streamlined office operations at Queensland Business Group—implementing a new filing system that reduced document retrieval time by 45% and coordinating meeting schedules for 6 executives with zero scheduling conflicts over 18 months—I’m excited about the opportunity to provide the reliable administrative support that keeps busy offices running smoothly.
Over the past three years working as an Office Assistant across Brisbane’s corporate and professional services sectors, I’ve consistently delivered outcomes that align perfectly with your requirements. I managed reception duties greeting 50+ visitors daily, coordinated travel and accommodation bookings, processed invoices and expense reports, maintained office supplies inventory, and provided administrative support including data entry, filing, correspondence preparation, and meeting coordination. My experience with Microsoft Office Suite, scheduling software, and office equipment has taught me that successful office support is equal parts attention to detail and proactive communication—exactly what you need for a professional corporate environment.
What really draws me to Brisbane Corporate Solutions is your reputation as a supportive workplace that values professional development. During my Certificate IV in Business Administration at TAFE Queensland, I developed skills in office procedures, business communication, and customer service, and I’ve since built expertise in calendar management, document preparation, and maintaining confidentiality with sensitive information. I’m passionate about proving that office assistants aren’t just task-completers—we’re essential team members who enable productivity, create positive first impressions, and ensure smooth daily operations.
I’d love to discuss how my track record of providing efficient, professional office support can contribute to Brisbane Corporate Solutions’ continued success. Thank you for considering my application, and I look forward to the opportunity to speak with you soon.
Kind regards,
Emily Roberts

What to Include in an Office Assistant Cover Letter (Australia)
Your Office Assistant cover letter needs to follow a clear structure that demonstrates both organizational capability and professional demeanor:
- Contact Details
- Salutation (Dear Hiring Manager or name)
- Opening paragraph – your hook and intent
- Middle – why you’re the best fit (skills + experience)
- Closing – call to action + sign off
Right vs Wrong Example
Right Opening: “When PwC Australia announced the opening of your new Brisbane office requiring administrative support for 30+ consultants, I immediately saw an opportunity where my experience providing multi-task office support—managing complex calendars for 5 senior executives, coordinating logistics for 20+ client meetings monthly, and maintaining filing systems for 2,000+ confidential client files—could ensure your new office operates efficiently from day one.”
Wrong Opening: “I am writing to apply for the Office Assistant position that was advertised on Seek. I have experience in administration and I believe I would be a good fit for this role at your company.”
Entry-Level Office Assistant Cover Letter Tips
- Focus on coursework, internships, or volunteer administrative experience
- Highlight transferable skills from retail, hospitality, or customer service roles
- Show proficiency with Microsoft Office and willingness to learn new systems
Entry-Level Cover Letter Sample for Office Assistant
Right Entry-Level Approach: “While completing my Certificate III in Business Administration at TAFE NSW, I completed a 10-week placement at Sydney Legal Partners where I answered phones, greeted clients, managed appointment schedules, prepared correspondence, maintained filing systems, and processed incoming mail for a busy 8-lawyer practice. I also worked part-time at Target for two years, developing strong customer service skills, cash handling experience, and the ability to remain professional under pressure during busy periods. This combination of formal business training and customer-facing experience taught me that effective office support requires organization, attention to detail, and friendly professionalism—skills I’m eager to apply in a full-time office assistant role.”
Wrong Entry-Level Approach: “I just finished my admin course and I’m looking for my first office job. I’m organized and friendly. I don’t have office experience yet but I’m good with computers and willing to learn. Please give me a chance to start my career.”
