Great administration is often invisible. Everything is simply where it needs to be, when it needs to be.

Trinity Grammar School is seeking a polished, highly reliable and exceptionally organised Administration Assistant – Operations to join our team at the Summer Hill Campus.

This is a varied, hands-on role supporting the smooth day-to-day operation of the School. You will coordinate administration for student excursions, incursions and camps, maintain accurate School calendar information, provide professional front-of-house and switchboard support, and assist with general operational administration.

What will matter most to us is how you work.

We are looking for someone who takes pride in getting the details right, follows things through without needing to be chased, presents professionally and can be trusted to manage their responsibilities independently.

Why Trinity?

Trinity is a workplace designed around more than just work

At Trinity, we want to be a workplace of choice, attracting people who are excellent at what they do and who want to contribute to a strong, values-driven community.

The working pattern offers an unusually attractive opportunity for an experienced administrator seeking a role that can work well alongside family and personal commitments, without stepping away from a meaningful and professionally engaging career.

Trinity Grammar School provides boys with a thoroughly Christian education in mind, body and spirit, and employees are expected to positively support the traditions, values and Christian ethos of the School.

If you are the person who spots the missing detail, follows up before being asked and takes genuine pride in making things run smoothly, we’d like to hear from you.

What we offer?

- Family-friendly hours: 7.30am to 2.30pm, Monday to Friday.
- Workplace of choice: join a professional, supportive Christian School community where your contribution is visible and valued.
- Variety:



your day might move between calendar coordination, excursion documentation, Reception, event logistics and operational administration.
- Autonomy: this would suit someone who enjoys taking ownership of their work and keeping things moving.
- Community: work in office as part of the daily life of a busy and highly engaged School.

This is an on-site position at our Summer Hill Campus, with no remote-working arrangement available. Hours will ordinarily be 7.30am to 2.30pm Monday to Friday, although some flexibility may occasionally be required to meet operational needs.

What you’ll be doing

Working as part of the wider operations team, you will work closely with the Director of Campus Administration to provide practical administrative support across several important areas of School operations, including:

- coordinating records and documentation and proactively following up outstanding information and documentation for excursions, incursions, camps, tours and overnight activities
- creating and maintaining accurate School calendar entries using Trumba
- providing a welcoming and professional Reception and switchboard service
- assisting visitors, parents, contractors, staff and other members of the School community

The person we’re looking for

You will ideally be someone who:

- is extremely reliable, punctual and dependable
- has a polished and professional presentation and communication style
- demonstrates strong attention to detail and notices when something does not look right
- works confidently and independently, while knowing when to ask or escalate
- takes ownership of tasks and follows them through to completion
- can manage interruptions and competing priorities without losing accuracy




- is comfortable following up others when information or documentation is outstanding
- communicates warmly and professionally with a wide range of people
- exercises discretion when handling confidential information
- is proficient in Microsoft 365 and comfortable learning systems such as Trumba.

Previous administration experience is essential, while experience within a school, education, events, calendar administration, reception or another busy multi-stakeholder environment would be particularly valuable.

The position requires a valid NSW Working With Children Check in employment status and First Aid/CPR qualifications, or willingness to obtain them.

We recognise that flexibility looks different for different people. This position can be structured to work either 44 weeks or 48 weeks per year, (plus four weeks’ paid annual leave) depending on the preference of the successful applicant. This provides the opportunity to choose the working arrangement that best suits your family, lifestyle and personal commitments.

The full-time equivalent salary range is $81,360 to $87,309 per annum, with salary paid pro rata according to the number of weeks worked. Your actual salary will therefore reflect whether you choose the 44-week or 48-week working arrangement.

Combined with the regular 7.30am to 2.30pm, Monday to Friday hours, this is an attractive opportunity for someone seeking meaningful, professional work while maintaining greater flexibility around life outside work.

At Trinity, people matter. While technology supports many aspects of our work, we believe recruitment should remain genuinely human. Your application will be considered by people, not selected by an algorithm or AI, because we want to understand the person, experience and potential behind every application.

In the same spirit, we encourage candidates to prepare their application in their own words rather than relying on AI to generate it for them. We are interested in hearing your voice, understanding your experience and getting a genuine sense of what you would bring to Trinity.
