That can make the role difficult to define. One organisation may need an administrator who keeps schedules, documents and internal systems in order. Another may rely on theirs to coordinate suppliers, support projects, assist senior staff and solve the small operational problems that otherwise land on someone else’s desk.

The common thread is that a capable office administrator creates capacity. By keeping work organised and making sure the right things happen at the right time, they allow other people in the business to spend more of their time on the work they were hired to do.

‍

What does an administrator do in an office?

There is no single answer, because office administration can cover a surprisingly broad range of responsibilities.

An office administrator may coordinate meetings and appointments, prepare documents, manage records, maintain databases, respond to enquiries, organise travel, order supplies, support internal processes or assist with projects and events.

The Australian Bureau of Statistics classifies clerical and administrative workers broadly as people who support managers, professionals and organisations by organising and managing information. Within that wider category sit a number of distinct occupations, from receptionists and executive assistants to office managers and project administrators.

In practice, that means the role of an administrator is usually shaped by the organisation around them.

A small business may need one person who works across several areas of office assistance. A larger organisation may have more specialised administrative professionals supporting particular teams, executives or functions. The needs of a professional services business in central Melbourne may look quite different from those of an organisation looking for office administration support in South East Melbourne.

‍

Office administrator, administrative assistant or office manager: what’s the difference?

Titles across administrative roles often overlap, which can make hiring confusing.

An administrative assistant will generally provide administrative support to an individual, team or business function. An executive assistant is more likely to work closely with senior leaders, often taking greater responsibility for diary management, stakeholder coordination, correspondence and competing executive priorities.

An administrative coordinator may have greater responsibility for coordinating a particular process, program or area of activity, while an office manager will generally have broader responsibility for the operation of the workplace itself.

Even these distinctions are not universal.

An “office administrator” in one business may perform work that another organisation assigns to an office manager or administrative assistant. For employers, the job title matters less than being clear about the work that actually needs to be done.

‍

The office administrator role is getting broader

Traditional administrative skills still matter, but good administrators increasingly contribute well beyond routine office tasks.

They may become a central point between departments, manage processes that cross several teams, pick up gaps in coordination or become the person others turn to when something needs to be organised, followed up or resolved.

This is part of what makes experienced administrative professionals so valuable. They develop an understanding of how an organisation works, who needs to know what, where information lives and which issues need attention before they become bigger problems.

The best administrators don't simply complete a list of tasks, but rather support team productivity by helping flow through the business.

‍

What skills does an office administrator need?

Technical capability remains important. Depending on the workplace, that may mean confidence using Microsoft 365, customer relationship management systems, databases, document management platforms, scheduling software or other business systems. But employers are also looking for qualities that are harder to capture in a software checklist.

Organisation is an obvious one, particularly when several people are relying on the administrator at once. Good communication matters because administrators regularly work across different teams, customers, suppliers and managers. Judgement is important when priorities compete or information is sensitive. Initiative becomes particularly valuable when the administrator can recognise what needs to happen without waiting for every task to be assigned.

This also helps explain what qualifies as useful administrative experience. Years spent in a particular job title can be relevant, but employers should also consider the responsibilities a person has managed, the environments they have worked in and the level of autonomy they are accustomed to.

Someone who has coordinated a busy team, managed several systems and dealt confidently with competing requests may bring highly relevant administrative experience even if their previous title was different.

How is technology changing office administration?

Technology has been changing administrative work for a long time, and AI and automation are adding another layer to that change. Jobs and Skills Australia’s Australian Jobs 2026 (which can be downloaded here) reports that jobs are more likely to be augmented by generative AI than automated, with the technology expected to change tasks, workflows and skill requirements rather than simply replace roles. Human judgement, interaction and oversight remain important across most occupations.

That shift is already starting to show up in the conversations WellsGray is having with candidates. Eleanor Methley says that when she interviews temporary and contract candidates, she will always ask what systems and software they are confident using.

“I don’t ask specifically about AI, but I’m listening for whether it comes up naturally in the way they talk about how they work. Over the past 12 to 18 months, it definitely has,” she says.

For office administration roles, that still means familiarity with the usual business tools and platforms, including Microsoft 365, monday.com, MYOB, Xero, Teams and SharePoint. But AI tools are increasingly becoming part of that same everyday toolkit.

Eleanor continues: “Candidates still talk about the usual admin software, but ChatGPT, Claude, Gemini and Copilot are now coming up much more often in interviews too. They’re increasingly being used to support everyday tasks rather than being treated as something separate.”

The key message here is that developments in technology don’t remove the need for capable administrators. Instead, they change where their value sits.

Software can automate a process, but somebody still needs to understand whether the process makes sense. AI can help prepare information, but somebody needs to know whether it is accurate, appropriate and useful. Systems can generate reminders and workflows, but they don't necessarily understand which competing priority matters most to the business.

As some repetitive work becomes easier to automate, human skills such as judgement, problem-solving, coordination and relationship management become increasingly important.

‍

When should you hire an office administrator?

Sometimes the need is obvious. A team member leaves, someone goes on extended leave or a business grows to the point where an additional position is required.

But there are less obvious signs too. If senior people are routinely spending time scheduling meetings, updating records, chasing information or coordinating routine processes, that may be a sign their capacity is being absorbed by work that could sit elsewhere.

The same can apply when administrative backlogs start to build, customer or internal enquiries are taking longer to manage, a project creates a temporary surge in work, or an existing team simply has more to coordinate than it can comfortably absorb.

The question isn't necessarily, “Do we need an office administrator?” A more useful question can be: “What work is taking up capacity in our business, and what kind of support would free it up?”

‍

A good admin hire starts with understanding what you actually need

Because administrative roles vary so significantly between organisations, hiring an office administrator shouldn't begin with a generic job description. We recommend starting with the work.

What needs to be taken off other people's plates? Which processes need more attention? Who will the administrator support? Which systems will they work in? Do you need someone who follows an established process, or someone confident enough to work things out as they go?

Those answers can also determine whether you need an office administrator, administrative assistant, executive assistant, office manager or another type of administrative professional. They can also help determine whether the need is ongoing.

Temporary administrative support isn't only useful for covering annual leave or an unexpected absence. Businesses may bring in temporary administrators to support projects, manage workload peaks, help during periods of change or create additional capacity while longer-term resourcing needs become clearer.

For employers looking for temporary office staff in Melbourne, that flexibility can be particularly useful when the work needs doing now, but the longer-term shape of the role is still taking form.

Finding the right temporary admin support

Once the need is clear, the next challenge is finding someone who can step into the role and contribute quickly.

This is exactly where experienced administrative staffing agencies can add value. Rather than matching candidates to a generic job title, a good recruiter should take the time to understand the responsibilities involved, the systems they will use, the pace of the workplace and the kind of person likely to work well within the team.
