You didn’t build your business so you could spend your days deciphering highly complex, industry-specific pay rates and conditions hidden within the Australian Modern Awards and second-guessing HR decisions.
Yet for many growing businesses, HR quietly becomes something you manage by default.
The question isn’t just whether to hire internally. It’s whether you can justify the remuneration, on-costs, time and risk of bringing one person in-house before there’s enough scale to truly support them.
This is where the choice between outsourcing HR and hiring internally comes into focus for small and medium-sized businesses.
Many leaders wonder why they should use external HR support at all when an in-house HR role sounds more familiar.
Growth naturally changes how you manage your team. In the early stages, handling a quick leave request or an onboarding question over coffee feels manageable. However, as your headcount increases, these interactions multiply.
Gradually, the time spent managing day-to-day people matters begins to outweigh your focus on core business operations.
As businesses grow, the question becomes less about whether HR should exist and more about how it should be resourced and supported.
When considering an internal HR hire, it’s important to look beyond salary alone and understand the broader investment involved, including ongoing employment costs, on-costs and operational overheads.
We’ll break down the differences, explore when each approach may be the right fit and help you assess what makes sense for your business stage and goals.
The Cost and Capability Equation
An internal HR hire adds salary, on-costs and overheads:
- Salary
- Super
- Payroll Tax
- Workers Compensation
- Bonuses/salary reviews
- Onboarding
- Software subscriptions
- Leave accruals (annual, personal, parental, long service)
- Cover when they take leave
- IP when they leave
Looking at that list brings the real cost of a dedicated role into focus. Internal HR professionals do incredible work, and hiring a full-time generalist makes perfect sense once your headcount is large enough.
But if your business is still in that middle growth phase, paying a full-time salary (often upwards of $90,000 base plus super) for a role that might only require part-time hours can stretch your budget unnecessarily.
A simple, practical step is to log your team’s HR hours over a typical two-month period.
If the HR work, like interpreting Modern Awards, updating policies, or managing leave accruals, only takes up 10 to 15 hours a week, a full-time hire isn’t required just yet.
Comparing that fixed salary to the flexible support of an outsourced HR partner gives you a much clearer picture of your options.
When you outsource HR, you only pay for what you need:
- The right level of compliance support
- Strategic advice when it matters
- Hands-on support when things get complex
- Legislatively compliant employee relations advice and guidance
- Recruitment, hiring and onboarding rhythm
- Proactive policy updates and legislatively compliant documentation to manage and protect sensitive employee data from breaches under the Privacy Act 1988
- Leadership coaching and capability support in real time
When you outsource HR the right way, you only pay for what you need:
Access to experienced HR professionals who understand your business, operate as part of your team, and step in at the right level at the right time, which for small to mid-sized businesses provides a fraction of the fixed costs of an internal HR generalist, with the added benefit of senior-level expertise.
The upside isn’t only dollars; it’s breadth. Outsourcing gives you access to a team of knowledgeable HR consultants who can support you across a variety of HR tasks, including compliance, employee retention, org design, talent and culture.
Signs you may be outgrowing your current HR approach include:
- Managers spending increasing amounts of time dealing with people issues.
- Onboarding and employee experiences becoming inconsistent.
- Policies and processes being updated reactively (or not at all) rather than proactively.
- The Founder becoming the default contact for all people-related matters.
- Employee issues becoming more complex as the business grows.
- Important HR initiatives continually being pushed down the priority list.
Recognising these signs can help you determine whether additional internal capability, outsourced HR support or a co-sourced approach may be needed.
Australian HR Compliance and Risks You Can’t Ignore
Australian employment law moves quickly. Getting it wrong can cost you thousands in fines, back pay and/or lost time.
Clear frameworks and processes help leaders navigate workplace issues consistently and confidently. They also make it easier to respond fairly when challenges arise and reduce the likelihood of problems escalating unnecessarily.
We take the pressure off by turning the main legislation governing Australian workplaces – the Fair Work Act 2009 – into simple, manageable actions that you or your leaders can actually follow.
For example, employers must manage psychosocial risks such as:
- Excessive workload
- Conflict
- Poor role clarity
And managing that requires:
- Psychosocial Risk Assessments
- The right policies
- Practical training
- Consistent follow-through
…not just posters on the wall.
Authoritative guidance sits with the Fair Work Ombudsman and Safe Work Australia. We create fit-for-purpose HR documentation bespoke to your unique business and align your day-to-day practices to those expectations so leaders can make decisions with confidence.
Speed, Scale and Continuity
Growth brings surges: new sites, restructures, increased headcount, seasonal hiring or a sudden lift in employee relations issues. A single internal HR generalist can struggle to keep up when the volume spikes. Relying on external HR support lets you scale on demand, without pulling you or your managers away from day-to-day work, customers, clients or operations.
Continuity matters too. If an internal HR hire resigns, valuable IP and knowledge walks out the door with them. A team-based outsourcing model protects your momentum with shared context, documented processes and service levels that don’t rely on one person.
Culture, Engagement and Performance
Great HR is more than policies and contracts. It’s clarity, coaching rhythms and building leadership capability to help managers confidently and competently handle the tricky conversations sooner rather than later.
We support people leaders to:
- Set clear expectations
- Build practical, proactive performance processes
- Improve role clarity so people know how to succeed
Strong performance practices help managers move beyond annual reviews and create more regular, meaningful proactive conversations that support employee growth and development.
This blend of human support and simple systems is where outsourced HR shines. You get the cadence and someone beside you to help build confidence. At Purple Playground HR, we call it ‘Systemising the process, Humanising the experience’.
When Does In-House HR Make Sense?
There’s a point where bringing HR in-house is the right move. For example, if you have 250+ employees, operate in a high-risk environment or operate in complex enterprise bargaining or unionionsed environments.
But even then, many businesses co-source. They’ll keep strategic and/or administrative HR work internal, and partner on specialist projects like workforce planning, recruitment, HRIs optimisations, engagement diagnostics or compliance reviews.
To help you draw the line, here is a quick guide on when to choose which strategy:
- Outsource HR If: You need access to professional HR expertise, additional capacity, or specialist support without commitment to a full-time role.
- Hire HR Internally If: You have the scale, complexity or day-to-day people requirements to justify a long-term dedicated internal HR function.
Use This Checklist to help you decide:
- Headcount and growth rate: Steady or surging?
- Complexity: Multiple Awards or enterprise agreements, shift patterns, operating across multiple states (like Qld, NSW and Victoria), or heavy union involvement.
- Risk exposure: Safety, psychosocial hazards and high employee relations load.
- Leadership expertise and bandwidth: Do managers need hands-on coaching?
- Budget flexibility: Fixed internal costs vs variable outsourced spend.
- Systems: Human Resource Information Systems (HRIS) maturity and reporting needs.
Where Does Purple Playground Fit?

For businesses weighing up outsourced or fractional HR, internal HR or a combination of both, we can help you assess your needs, growth plans and internal capability so you can choose the right approach for your stage of growth.
Still Deciding?
If you’re comparing HR outsourcing vs in-house HR, remember the trade-offs:
- Outsourcing: variable cost, broader expertise, no single point of failure
- In-house: closer day-to-day proximity, single expertise, higher long-term fixed cost
- Co-sourced: the best of both when you are ready, depending on your needs
The “right” model depends on your headcount, complexity, growth stage and internal capability.
Managing your team should feel like a natural part of your business rather than a late-night administrative burden. Having the right human-centred support and frameworks in place gives you greater clarity, consistency and confidence as your business grows.
