Should your Melbourne business hire an internal IT person or use a managed IT provider? A frank comparison of cost, capability, coverage, and risk for businesses of different sizes.
The decision to hire an in-house IT person or use a managed IT provider is one that most Melbourne businesses approach as a cost question. It is actually a capability and risk question — and when framed correctly, the right answer for most Melbourne SMBs becomes significantly clearer.
This guide compares managed IT and in-house IT honestly — not from the perspective of an IT provider who obviously favours managed IT, but from the perspective of what actually works for Melbourne businesses of different sizes and complexity levels.
The True Cost of In-House IT in Melbourne
The salary is the visible cost. Everything else is frequently underestimated.
Base salary
An IT support person (IT coordinator, systems administrator, or IT manager) in Melbourne in 2026:
- IT coordinator/junior sysadmin (1–3 years experience): $65,000–$85,000
- IT manager (5–8 years experience): $95,000–$130,000
- Senior sysadmin / IT director (10+ years): $130,000–$180,000+
For most Melbourne SMBs of 20–50 staff, the appropriate hire is an IT manager in the $95,000–$115,000 range. Budget $100,000 as a working assumption.
Total employment cost
Base salary is typically 65–70% of total employment cost. Add:
- Superannuation (11.5% of salary): $11,500
- Annual leave loading and long service leave accrual: $5,000–$8,000
- Workers compensation and payroll tax: $4,000–$8,000
- Recruitment cost (typically 10–15% of first year salary, amortised over tenure): $5,000–$10,000
Total cost of a $100,000 salary IT manager: approximately $130,000–$140,000 per year.
Additional IT costs that do not disappear
An in-house IT person still needs tools and resources to operate:
- RMM (Remote Monitoring and Management) platform: $3,000–$6,000/year
- Microsoft 365 and licences: same as with managed IT
- Security tooling (EDR, email security, firewall management): $15,000–$30,000/year
- Training and certification to stay current: $3,000–$8,000/year
- Hardware and equipment: same as with managed IT
Additional tooling and training on top of employment: $25,000–$45,000 per year.
Total real cost of in-house IT for a Melbourne 50-person business
Combined employment and tooling cost: $155,000–$185,000 per year.
At $129 per user per month, a managed IT service for 50 users: $77,400 per year — less than half the in-house cost, with more capability (a team versus one person) and no key-person dependency.
The Capability Problem With In-House IT
A single IT person is excellent at some things and limited in others. The challenge is that a growing Melbourne business needs expertise across an increasingly broad range of domains:
- Microsoft 365 administration and security (specialised knowledge)
- Networking and firewall management (different skill set)
- Cyber security — EDR, email security, Essential Eight (requires current specialisation)
- Cloud infrastructure (Azure, AWS — another specialisation)
- Compliance frameworks (healthcare, legal, financial services requirements)
- End-user helpdesk support (operational, not strategic)
- vCIO and IT strategy (senior skill, different from technical operations)
- Vendor management
- Business continuity and disaster recovery planning
No single person is deeply skilled across all of these. An IT manager hired for their networking strength will have gaps in cyber security. One hired for Microsoft 365 expertise will struggle with complex infrastructure. One who is excellent at helpdesk support will not be developing a meaningful technology strategy.
A managed IT provider employs specialists across all these domains. When your business faces a networking issue, a networking specialist responds. When a cyber security incident occurs, a security engineer handles it. The depth of expertise available is simply not replicable in a single hire.
The Coverage Problem
An in-house IT person works approximately 220 days per year. They are on leave for the remaining 28 working days. They get sick occasionally. They attend training. They sometimes leave — voluntarily, suddenly, and inconveniently.
During all of those periods, your IT coverage depends on their goodwill (checking emails on holiday), expensive contractor arrangements, or simply no coverage at all.
A managed IT team covers your environment 5 days per week regardless of any individual’s leave or departure. After-hours coverage, if required, is an escalation model rather than a single person’s personal availability.
For Melbourne businesses where IT downtime has significant business impact — professional services with client commitments, healthcare with patient care obligations, financial services with transaction processing — single-person coverage dependency is a genuine business risk that managed IT eliminates.
The Key-Person Dependency Risk
The most underappreciated risk of in-house IT is the knowledge concentration it creates. When your IT person leaves — and over time, they will — a significant amount of institutional IT knowledge leaves with them.
Where are the passwords? Which vendor relationships does the business have? What is the network configured to do and why? Where are the backup keys stored? What is the procedure for a specific system failure?
With a well-run managed IT provider, this knowledge lives in documented runbooks, ticketing systems, and configuration management platforms. It is accessible to the team and survives any individual’s departure. With an in-house IT person, it often lives in their head and their personal note-taking system.
The transition period when an IT manager leaves — typically 2–6 months to recruit and onboard a replacement — is a period of heightened IT risk and reduced capability for Melbourne businesses dependent on a single person.
When In-House IT Makes Sense
In-house IT is the right answer for some Melbourne businesses. The profile where it makes sense:
Over 100–150 staff with significant IT complexity. At this scale, the economics shift. A fully-staffed internal IT team (not a single person) can provide the coverage, depth, and institutional knowledge that managed IT cannot replicate at the same cost. The investment in multiple in-house specialists becomes justified.
Specific regulatory environments requiring dedicated internal expertise. Some Melbourne businesses — certain government contractors, regulated financial services, specific healthcare settings — need IT staff who are employees for compliance reasons, not just preference.
Highly specialised IT environments. Businesses with custom-built systems, legacy infrastructure that requires deep institutional knowledge, or very specific industry applications sometimes benefit from a dedicated internal resource who understands those systems in depth.
Where in-house IT does not make sense is the Melbourne SMB of 15–80 staff with standard Microsoft 365 infrastructure, commercial applications, and a mix of IT needs across cyber security, cloud, and helpdesk. This profile — which describes most Melbourne professional services businesses — is almost universally better served by a quality managed IT provider.
The Co-Managed IT Model: Best of Both
For Melbourne businesses in the 80–200 staff range, neither pure in-house nor pure managed IT is necessarily the optimal answer. The co-managed model combines both:
- An internal IT coordinator (or IT manager) manages the day-to-day IT relationship, handles user requests, manages IT projects, and serves as the internal IT business partner
- A managed IT provider supplies the specialist depth, security tooling, monitoring infrastructure, and 24/7 coverage capability that the internal person cannot provide alone
This model works well when the internal person is strong at relationship management and strategic alignment but needs specialist support for security, infrastructure, or complex technical issues. The managed IT provider fills the gaps without replacing the internal resource.
A Decision Framework
Use this to guide your decision:
Likely managed IT is right if:
- You have 15–80 staff
- Your IT is primarily Microsoft 365, standard applications, and commercial networking
- You have no dedicated internal IT staff currently and are making your first IT investment
- Budget is a constraint and you need maximum value per dollar
- You have compliance obligations (healthcare, legal, financial) that require security expertise
Likely in-house IT is right if:
- You have 150+ staff and can build a team of 3+
- You have genuinely specialist IT requirements (custom systems, specific regulatory environments)
- You already have an IT team and are evaluating whether to expand it
- You need an IT person who is deeply embedded in your business culture and operations
Likely co-managed IT is right if:
- You have 80–200 staff
- You have or need an internal IT coordinator but also need specialist depth
- Your IT complexity has grown beyond what one person can manage alone
- You want internal IT presence with external specialist support
The Bottom Line
For most Melbourne businesses under 80 staff, the business case for managed IT over in-house IT is clear: more capability, better coverage, no key-person dependency, and lower total cost. The comparison looks superficially closer when you compare salary to managed IT fee — but when you account for total employment cost, tooling, training, leave coverage, and the depth of expertise available, managed IT consistently wins.
The right question is not whether managed IT or in-house IT is cheaper. It is which model gives your Melbourne business the right capability, the right coverage, and the right risk profile for your size and complexity.
