Virtual assistant vs AU temp agency – short-term and ongoing trade-offs

The table gives you the headline rates. What it can’t show is what either option actually costs once the engagement is running and the hidden line items appear. Below is a worked example in AUD, the factors that genuinely decide the call, where each model fails, and a plain read on who should pick which.

What 20 hours a week for six months actually costs

Take a common scenario: a Melbourne services business needs roughly 20 hours a week of admin, inbox triage, and customer follow-up for six months. That’s about 520 hours over the period.

A DotVA admin placement sits at $12-17/hr. Call it $15/hr at the admin tier, so 520 hours lands around $7,800. The management overhead is real but small: you brief one dedicated person who learns your systems and stays, so by week three the back-and-forth has mostly stopped. Recruitment risk is carried by the 30-day satisfaction guarantee (free replacement) and the $500 refundable deposit, so a bad fit costs you a reset, not the engagement. No super, no leave loading, no payroll tax, no desk. Total true cost over six months: roughly $7,800-8,800, including a modest allowance for your own onboarding time.

A temp agency is solving a different problem, and the price reflects it. Temp rates in Australia typically run $50-80/hr inclusive of the agency margin at time of writing, so 520 hours lands somewhere near $26,000-41,600. The work gets covered fast and the person can be in your office, but you’re often onboarding a new face each assignment, so your context-building time resets and continuity suffers. For a strictly short engagement that premium can be worth every dollar. For six months of the same recurring admin, you’re paying emergency-cover rates for a baseline function.

For reference, a comparable local AU hire runs roughly $35-45/hr loaded once you add super, leave, and on-costs (our estimate), so the temp premium is real, but so is the speed and presence you’re buying. To model your own hours and tiers, the VA cost calculator does the arithmetic, and the 2026 guide to VA costs in Australia breaks down the on-cost maths behind that loaded figure.

The factors that actually decide it

Three things matter day to day, well beyond the hourly number.

Duration fit comes first. Temp margins are built around short, high-rate placements, so they’re priced to be temporary. The moment a role becomes ongoing, the rate that felt sharp for three weeks becomes the most expensive way to staff a permanent function.

Continuity is second. A temp who rotates off after an assignment takes your process knowledge with them. A dedicated VA working your local Australian hours is the same person every day, which is why an ongoing function like executive assistant work or general admin support compounds in value rather than resetting each month.

Presence is third. Some work genuinely needs an Australian resident physically on site: signing for deliveries, covering a front desk, handling documents that can’t leave the building. That requirement alone can settle the decision before cost enters the conversation, because a remote-by-design model can’t do it.

Where each option falls down

Both models fail in predictable ways, and we’d rather you know ours.

The temp agency’s weakness is cost-per-context. You pay top rates and still risk a different person each engagement, so anything needing deep familiarity with your business gets re-learned repeatedly. Continuity is structurally not what they sell.

DotVA’s managed model is the wrong choice in several situations, and we’ll say so plainly. If the work must happen in person, we can’t help: we’re remote-by-design with no offices. If you need someone starting tomorrow, our 7-10 day matching window is too slow, and a temp wins on speed. If the role is genuinely a few weeks of cover for parental or sick leave with an AU-presence requirement, paying for an ongoing dedicated relationship makes no sense. And if you want to hand over a vague brief and have it figured out from day one, a VA needs clearer direction than a senior temp who’s done the role a dozen times. We vet hard, which is why we publish exactly how we screen and match, but vetting doesn’t replace a clear scope.

Pick this if, pick that if

Pick a temp agency if you’re covering a defined short gap, the work needs an Australian on the ground, or you need someone in the seat within days. A retailer staffing a December peak, or a clinic covering eight weeks of parental leave at the front desk, should call a temp and not us.

Pick a DotVA placement if the function is ongoing and remote: recurring admin, inbox and calendar, customer follow-up, bookkeeping support, content production. A consultancy drowning in scheduling, or a trades business chasing invoices and tidying its CRM every week, reclaims 15-20 hours a week with one dedicated person at a fraction of temp rates. Our pricing tiers are published in full so you can sanity-check the maths against your own situation.

Often the smartest AU small business does both: a VA for the ongoing baseline, a temp agency on standby for the genuine emergency. They aren’t rivals. They cover different gaps.
