- In-house IT means employing dedicated IT staff who work exclusively for your organisation. An outsourced MSP provides IT support, infrastructure management, and cybersecurity through an external provider.
- In-house IT gives you deep business knowledge and immediate physical presence, but is limited by headcount, skill breadth, and availability.
- An MSP delivers a full team of specialists, 24/7 coverage, and enterprise-grade tools for a predictable monthly fee — typically at a lower total cost than equivalent in-house capability.
- The co-managed model — combining a small in-house team with an MSP partner — is increasingly popular among Australian businesses with 50–500 employees.
The In-House IT Model
In-house IT means hiring one or more full-time employees to manage your technology environment. They sit in your office, understand your business processes, know your staff by name, and can physically walk to a desk when someone needs help. For many businesses, that on-site presence and institutional knowledge is invaluable.
A typical in-house IT setup for a 50-person business might include one IT manager or systems administrator and possibly a junior support person. This two-person team handles everything: help desk support, server management, network administration, cybersecurity, vendor management, project work, and strategic planning.
The challenge is obvious. Two people cannot be experts in everything. They can't provide 24/7 coverage. When one is on leave or sick, you're down to a single point of failure. And the breadth of skills required — networking, security, cloud, Microsoft 365, backup, compliance, telephony, hardware — exceeds what any individual can master.
The Outsourced MSP Model
An outsourced managed service provider (MSP) delivers IT support and management through a team of specialists, backed by enterprise-grade tools and established processes. Instead of employing your own IT staff, you partner with a provider who takes responsibility for your technology environment.
A typical MSP engagement includes: a dedicated help desk with guaranteed response times (SLAs), 24/7 infrastructure monitoring, patch management and updates, cybersecurity services (endpoint protection, email filtering, backup management), vendor management (liaising with Microsoft, Telstra, your ISP, etc.), strategic IT planning and budgeting, and project work (office moves, cloud migrations, new system deployments).
The MSP model gives you access to a team of 10, 20, or 50+ specialists across all IT disciplines — at a fraction of the cost of employing them directly.
The Cost Reality
In-house IT costs more than most businesses realise. A competent IT manager in Sydney commands a salary of $110,000–$150,000. Add superannuation (11.5%), workers' compensation, leave entitlements, training, and professional development, and the true cost is $140,000–$190,000 per person. For a two-person team providing basic coverage, you're looking at $250,000–$350,000 per year in staff costs alone — before tools, licences, or infrastructure.
In-House IT: 50-Person Business
Two-person team: $250,000–$350,000/year in staff costs alone. Add tools, licences, and training: $280,000–$400,000+ per year total.
Outsourced MSP: 50-Person Business
$5,000–$9,000/month ($60,000–$108,000/year) — full team of specialists, 24/7 monitoring, enterprise security tools, and help desk included.
The cost advantage is even more pronounced when you factor in the tools. A properly equipped in-house IT team needs a remote monitoring and management (RMM) platform, a ticketing system, endpoint protection, SIEM or security monitoring, backup software, documentation tools, and various licences. These tools typically cost $2,000–$5,000 per month for a 50-person environment. MSPs absorb these costs into their monthly fee because they amortise them across all their clients.
| Cost Factor | In-House IT (50 staff) | Outsourced MSP (50 staff) |
|---|---|---|
| Staff Salaries (2 people) | $220,000–$300,000 | Included |
| Super & On-Costs (25–30%) | $55,000–$90,000 | Included |
| Tools & Licences | $24,000–$60,000/yr | Included |
| Training & Certs | $5,000–$15,000/yr | Included |
| After-Hours Coverage | Not included | Included |
| Total Annual Cost | $280,000–$400,000+ | $60,000–$108,000 |
The Co-Managed Model: Best Of Both Worlds
Increasingly, Australian businesses are finding that the optimal approach isn't either/or — it's both. The co-managed IT model pairs a small in-house team (typically 1–3 people) with an MSP partner. The in-house team provides the business context, physical presence, and first-line support that benefits from being on-site. The MSP provides the 24/7 monitoring, specialist expertise, cybersecurity, and infrastructure management that requires a larger team.
In practice, the co-managed model might look like this: your internal IT manager handles day-to-day user support, project coordination, and vendor relationships; the MSP handles monitoring, patching, security operations, after-hours incidents, and specialist projects like network upgrades or cloud migrations. Each party does what they do best.
