A systems administrator looks after the servers, storage, identity systems and cloud accounts that the rest of a business uses without thinking about them. The job sits closer to infrastructure than a network engineer, who works more narrowly on the switches and traffic between systems, and it carries more responsibility for production systems than an IT support officer answering helpdesk calls. Most work inside a dedicated IT team, a cloud provider or a managed service provider, and many take on-call cover for after-hours incidents.
How much do systems administrators earn?
The median full-time salary for a systems administrator is $128,000 per annum, before tax, up $27,200 since 2018.
Pay moves with the sector and the size of the employer, so government departments and large enterprises usually work under an enterprise agreement with defined increments, while managed service providers often pay less for the same title. Certifications in cloud platforms and virtualisation can lift what an employer offers, and on-call allowances and after-hours penalty rates add to a base salary. In a small IT team you may cover everything, while specialists in larger organisations are paid for depth in one area.
What does a systems administrator do day to day?
The list below is what fills most weeks; the exact mix shifts with seniority and whatever stage the current work is at.
- Patching and updating servers in a maintenance window, usually outside business hours so as few people as possible are affected
- Working through a queue of support requests while a longer migration or upgrade sits half-finished
- Setting up accounts, permissions and group policies in Active Directory as staff join, change teams or leave
- Checking monitoring alerts in Nagios or Zabbix and working out which ones need attention now and which can wait until morning
- Building or resizing a virtual machine in VMware or a cloud platform for the team that asked for it

Is the job growing?
About 14,700 people work as systems administrators in Australia, and employment is projected to grow 24% over the decade to 2035. That's very strong growth. Few roles in Australia are expanding this fast, and it points to solid demand for years to come.
How do you become a systems administrator?
Here's the path most systems administrators take, step by step.
- 1Study IT at university or TAFE
A bachelor degree in information technology or computer science is held by about 35% of the people working as systems administrators today. A diploma or advanced diploma takes less time and costs less, and many employers accept it alongside vendor certifications.
- 2Start in a support role
Many systems administrators begin on a helpdesk or as an IT support officer, where they learn the ticketing system, the users and the shape of the environment before taking responsibility for servers. That work is paid, and some employers value it more than a stronger academic record.
- 3Add vendor certifications
Microsoft, AWS, VMware and Linux certifications such as the Red Hat RHCSA show platform-specific knowledge that employers ask about at interview, and most are short courses you can take while working. They matter most where your degree or diploma did not cover the platforms the employer actually runs.
- 4Get used to on-call and scripting
An on-call rotation is common, so new starters should expect some nights and weekends on the roster. Learning PowerShell, Bash or Python and infrastructure-as-code tools such as Terraform is what separates administrators who keep a system running from those who automate it.
- 5Expect background checks in some sectors
No licence or registration is required to work as a systems administrator in Australia, but roles in government, defence, health and finance usually need a police check and sometimes a security clearance, which has to be granted before you start.
Ready to apply as a systems administrator?
Whether you're working toward becoming a systems administrator or already are one and want a hand with the next step (sharpening your resume for ATS screening, tightening your cover letter, or knowing what you'll actually be asked at interview), here are examples grounded in this specific role, not generic templates.
What jobs can a systems administrator move to?
Moving into DevOps Engineer typically comes with the biggest pay rise, worth $3,900 a year more on average.
| Move to | Typical pay change | Overlap | Retraining |
|---|---|---|---|
| DevOps Engineer Systems administrators automate servers and deployments, so moving into DevOps engineering extends those skills into pipelines and infrastructure as code.Known move | +$3,900 | 31% | reskill |
| Database Administrator Database administration is a close specialism, with systems administrators already handling servers and backups, so the move needs little extra training.Known move | +$0 | 61% | minimal |
| Cyber Security Analyst Systems administrators know systems and access controls, so they can specialise in cyber security analysis with further study in threat detection.Known move | +$0 | 44% | reskill |
| Network Engineer Systems administrators already manage networks, so moving into network engineering builds on that routing and switching knowledge with a short course.Known move | −$7,900 | 48% | short course |
| Cloud Engineer Systems administrators work with servers and virtualisation, so cloud engineering is a natural step after a short course in cloud platforms. | −$16,200 | 50% | short course |

What's it like being a systems administrator?
The work has a steady rhythm of routine maintenance broken by sudden incidents, and the days rarely go to plan. A quiet morning can turn into an outage call within minutes, so it suits people who are comfortable being interrupted, methodical about documenting what they change, and unruffled when someone is standing behind them waiting for an answer. If you like problems with a definite cause and a definite fix, there is plenty here to keep you interested.
What people like
- Problems with a definite cause. A full disk, a broken DNS record or an expired certificate has an explanation, and tracking it down is the satisfying part of the job.
- Systems you set up disappear into the background. Once a server, a backup routine or an automated deployment is working, it runs for months without anyone noticing, which is the point of it.
- There is always a new platform to learn. Cloud services, server versions and tools change constantly, so the job never settles into a fixed set of tasks, and certifications are easy to fit around work.
- You can specialise without leaving the field. Cloud, security, virtualisation and databases all grow out of the same foundation, so you can shift direction as your interests change.
What people find hard
- You are most visible when something breaks. A year of clean uptime passes without comment, while a two-hour outage gets a review and a set of questions about what happened.
- Interruptions set the day's priorities. Planned work is the first thing to go when production goes down, so projects that need concentration stretch out over weeks.
- Nights, weekends and on-call. Patching and upgrades usually happen outside business hours, and someone has to answer the phone when a system fails at 2am.
- Old systems stay in service. Replacing ageing hardware or an unsupported server needs budget and approval, so administrators often keep a system alive well past its sensible life.

Will AI replace systems administrators?
AI and automation reach a moderate share of this job. Routine patching, alert triage and account provisioning are increasingly scripted or handled by management platforms, but diagnosing an unfamiliar fault in a specific environment remains hands-on work. Monitoring and configuration tools have been reshaping the role for years, moving it from direct server work towards automation, code and cloud platforms, and that shift continues.
Share of typical working time by exposure level
- Patching and scheduled maintenanceUpdate tools now push patches across a fleet on a schedule, so much of the work is approving changes, checking the results and fixing the servers that fail.30%high
- Monitoring and alert triageZabbix, Nagios and cloud monitoring already group and filter alerts, which cuts the noise but still leaves an administrator to decide which alert matters and why one host is behaving differently.25%moderate
- Hardware, on-site work and incident responseReplacing a failed drive, racking a switch or sitting with a vendor while they trace a fault in a legacy system is physical, specific work that automation cannot do.25%low
- Accounts, permissions and access changesCreating users and changing group policies in Active Directory is largely scripted, though requests still arrive by email and have to be matched to the right approval.20%moderate
Common questions about becoming a systems administrator
Straight answers to the questions people ask most.
How much do systems administrators earn?
Systems administrators earn a median of $128,000 per annum, before tax, based on full-time worker figures for the role. Pay varies with the sector, with government and large enterprises generally paying above managed service providers for similar work, and with certifications in cloud platforms or security. The median covers everyone from first-year administrators to people with fifteen years in the job, so it is a midpoint rather than a starting point.
How do you become a systems administrator?
Most people get there through an IT degree or diploma, then a year or two in a helpdesk or support role, adding vendor certifications as they go. You do not need a licence or registration in Australia, but government and defence roles usually require a police check and sometimes a security clearance.
Are systems administrators in demand?
Systems administrators are currently not in shortage, and employment is projected to grow 24% over the decade to 2035. Advertised roles cluster around cloud infrastructure and security, and larger employers in government, education and professional services are among the steadiest sources of work. Employers increasingly want people who can manage both on-premises servers and cloud environments rather than only one.
Will AI replace systems administrators?
AI and automation already handle parts of the job, particularly scheduled patching, alert filtering and routine account changes, so the role is moderately exposed rather than untouched. The harder parts stay with the administrator: diagnosing why one specific server behaves oddly, holding a legacy environment together, and dealing with the people affected by an outage.
What can systems administrators move into?
Network engineering builds on the routing and switching you already manage and needs only a short course, though pay is $7,900 less. Database administration uses much of the same server and backup knowledge, with pay about the same. DevOps engineering extends automation skills into deployment pipelines, with pay $3,900 more.
What is the difference between a systems administrator and a network engineer?
A systems administrator looks after servers, storage, identity and cloud services, while a network engineer concentrates on the routers, switches and traffic that connect them. The two roles overlap in small teams, where one person often covers both, and they separate in larger organisations where each has its own team.
