"I'll just hire someone part time, it'll be cheaper than a virtual assistant service." I hear a version of this from Australian business owners constantly, and on the surface it sounds reasonable. Fewer hours should mean a smaller bill. The problem is that this assumption skips over exactly the costs that make part time employment genuinely expensive, costs that do not actually shrink just because the hours do. Let me walk you through the real numbers.

The Part of Part Time Employment Nobody Budgets For

A part time employee in Australia is a permanent employee, just working fewer hours, and permanent status brings the full weight of statutory on-costs with it, calculated proportionally rather than waived. Superannuation sits at twelve percent of ordinary time earnings as of the current financial year, and it applies to every dollar of wages regardless of whether that person works fifteen hours a week or thirty eight. Annual leave, personal leave, and long service leave all accrue on a pro rata basis for part time staff, exactly as they do for full time employees, just calculated against fewer hours.

Once you add workers compensation insurance, typically one to three percent of wages for an office based role, the combined statutory on-cost for a permanent employee, part time or full time, commonly lands somewhere between twenty five and thirty five percent above the base wage, sometimes reaching closer to forty percent once payroll administration and standard operational overhead are factored in. This percentage does not shrink because the role is part time. It applies just the same, proportionally, to a fifteen hour week as it does to a thirty eight hour one.

The Fixed Costs That Do Not Care How Many Hours You Hire For

Here is the part that genuinely catches business owners off guard, and it is the actual heart of why part time hiring often costs more per hour than people expect. Recruitment costs a business somewhere between five thousand and twenty five thousand dollars per hire in Australia, depending on the role and location, and that cost is essentially identical whether you are hiring someone for fifteen hours a week or thirty eight. The same applies to onboarding time, a desk, a laptop, software licences, and the management attention needed to train someone properly in their first few months.

None of these fixed costs scale down with reduced hours. A part time employee working fifteen hours a week still needs the same onboarding investment as someone working full time, which means that investment gets spread across far fewer working hours, quietly inflating the effective hourly cost of a part time hire well beyond what the wage alone suggests.

What This Actually Looks Like in Real Numbers

Take a genuinely common scenario, a part time admin hire working fifteen hours a week at thirty dollars an hour base wage. That is four hundred and fifty dollars a week in base wages, or roughly twenty three thousand four hundred dollars a year. Add a thirty percent on-cost loading for superannuation, leave accrual, and workers compensation, and the true annual cost climbs to somewhere around thirty thousand dollars. Spread that across the actual seven hundred and eighty hours worked in a year, and the effective loaded hourly rate sits closer to thirty nine dollars an hour, well above the thirty dollar figure on the offer letter, before recruitment and onboarding costs are even factored in separately.

What a Virtual Assistant Actually Costs by Comparison

Virtual assistant services in Australia typically run thirty five to sixty five dollars an hour for an Australian based assistant, or eight to twenty dollars an hour for a properly vetted offshore assistant, commonly based in the Philippines. Critically, there is no superannuation, no leave accrual, no workers compensation, and through a managed provider, no separate recruitment fee sitting on top. You pay for the hours actually worked, and nothing else.

Run the same fifteen hour a week comparison using an offshore virtual assistant at fifteen dollars an hour, and the annual cost sits around eleven and a half thousand dollars, against roughly thirty thousand dollars for the part time employee once every true cost is included. Even comparing against an Australian based virtual assistant at fifty dollars an hour, the annual cost lands close to thirty nine thousand dollars, broadly comparable to the part time employee once loaded properly, but without the fixed recruitment cost, the management overhead of training someone from scratch, or the risk of a bad hire requiring you to start the entire process again.

Where the Comparison Genuinely Gets Closer

I want to be fair here rather than present this as an obvious win in every scenario. Comparing a part time employee against an Australian based virtual assistant specifically, the total cost gap is real but not always dramatic once everything is loaded properly. The clearest, most consistent cost advantage shows up specifically when comparing against a properly vetted offshore virtual assistant, where the gap regularly runs to tens of thousands of dollars a year for a comparable weekly commitment.

Where Part Time Employment Still Makes Sense

A part time employee still makes more sense when a role genuinely requires physical presence, a receptionist greeting people at the front desk, someone required on site for compliance or safety reasons, or a role you are specifically building as a long term career pathway toward a more senior position within your business. Virtual assistant arrangements are generally better suited to defined operational scope than long term in-house career development.

Why the Onboarding Risk Matters as Much as the Dollar Figure

Beyond the raw numbers, there is a genuine risk difference worth weighing. If a part time hire does not work out, you are looking at a fresh recruitment round, another five to twenty five thousand dollars in hiring costs, and months of lost productivity while you find and train a replacement. A properly managed virtual assistant arrangement typically allows a far faster, lower cost replacement process if a specific match is not working out, since a reputable provider carries the vetting and matching responsibility rather than you starting entirely from scratch.

Getting the Comparison Right for Your Specific Business

The genuinely smart approach is not assuming either option is automatically cheaper, it is running the real numbers for your specific situation, hours needed, local wage rates, and whether the role genuinely requires physical presence, before deciding. For most Australian businesses considering part time admin or operational support, that comparison consistently favours a properly matched virtual assistant, particularly once recruitment risk and fixed onboarding costs are counted honestly alongside the hourly rate.

This is exactly the standard we hold every placement to, matching you with a properly vetted, trained virtual assistant rather than leaving you to weigh this decision with incomplete numbers. If you are comparing a part time hire against virtual assistant services and want the real cost picture for your specific situation, our virtual assistant service is built to help you make that call properly.

The Bottom Line

A part time employee is not automatically the cheaper option just because the hours are fewer. Superannuation, leave entitlements, and workers compensation apply proportionally regardless of hours worked, and fixed costs like recruitment and onboarding do not shrink at all just because the role is part time, which quietly inflates the true hourly cost well beyond the number on the wage. For most Australian businesses considering fifteen to twenty five hours a week of admin or operational support, running the honest, fully loaded comparison is worth doing before assuming part time employment is the cheaper path.

Frequently Asked Questions

Do part time employees in Australia get the same entitlements as full time employees?
Yes, on a pro rata basis. Superannuation, annual leave, personal leave, and long service leave all apply to part time employees proportionally based on hours worked, meaning the percentage on-cost above base wage is essentially the same as for a full time employee.

Why does a part time employee sometimes cost more per hour than expected?
Fixed costs like recruitment, onboarding, equipment, and management training time do not scale down with reduced hours. A part time hire working fifteen hours a week still requires the same onboarding investment as a full time hire, which gets spread across far fewer working hours, inflating the effective hourly cost.

Is a virtual assistant always cheaper than a part time employee?
Not always, particularly when comparing against an Australian based virtual assistant specifically, where the gap can be modest once everything is loaded properly. The clearest, most consistent savings show up when comparing against a properly vetted offshore virtual assistant.

What is the biggest hidden cost of hiring a part time employee in Australia?
Recruitment cost is often the most underestimated factor, typically running five to twenty five thousand dollars per hire depending on the role and location, a cost that applies in full regardless of whether the role is fifteen hours a week or thirty eight.
