How Much Does a Penetration Test Cost in Australia?

In Australia, a professionally delivered penetration test typically costs between AU$6,000 and AU$18,000+, depending on what is being tested and how big it is. Rather than make you email three vendors to find that out, here are our actual guide prices, what pushes a quote up or down, and how fixed-price scoping works.

Ironbark's guide prices

These are our real public guide ranges, not bait:

Web application or API penetration test: AU$8,000–18,000 (5–10 days of testing)
External network penetration test: AU$6,000–12,000 (4–7 days)
Cloud penetration test (AWS, Azure, GCP): AU$6,000–14,000 (4–8 days)
ISO 27001-scoped penetration test: AU$8,000–16,000

Where your engagement lands within a range depends entirely on scope — which is why every quote starts with a scoping conversation, and why we give a fixed price rather than an estimate.

What you are actually paying for: days

Penetration testing is priced on skilled human time. The cost of an engagement is essentially the number of testing days your scope requires, multiplied by a day rate that reflects the seniority of the people doing the work. Everything that moves a quote — up or down — moves it by changing one of those two numbers.

That is also why prices vary between vendors quoting the 'same' test: different day rates, different seniority, different amounts of actual manual testing, and sometimes a different product entirely (an automated scan wearing a pentest label — see penetration test vs vulnerability scan).

What drives the cost up

For a web application or API test, the big drivers are:

Application size. More screens, endpoints and workflows mean more to test. A 20-endpoint API and a 300-endpoint platform are different engagements.
Number of user roles and tenants. Authorisation testing effort grows with every role and tenancy boundary, because each pair of roles is a set of access-control checks to attempt.
Complex authentication and integrations. SSO federation, payment flows, third-party integrations and file handling all add depth worth testing properly.
Multiple environments or scopes. Web app plus API plus cloud review is more days, though combining them in one engagement is cheaper than three separate ones.
Compliance-grade reporting. Mapping findings to ISO 27001 or PCI DSS requirements, attestation letters, and auditor-ready documentation add reporting effort.
Constraints. After-hours-only testing windows or urgent turnarounds compress schedules and add cost.

For external network testing, the driver is simpler: the number of live hosts and exposed services. For cloud testing, it is the number of accounts/subscriptions and the sprawl of services in use.

What drives the cost down

You have more control over price than you might think:

A tight, honest scope. Testing your crown jewels deeply beats testing everything shallowly. Rotate lower-risk systems into future engagements instead of cramming them all in.
Good documentation. An accurate OpenAPI spec or Postman collection can save a day of reverse-engineering an API — that saving flows straight into the quote or into deeper testing.
Preparation. Test accounts created, VPN access working, staging seeded with data. Wasted days get scoped into quotes; well-prepared clients do not pay for them.
Scheduling flexibility. If your test can slot into a quieter period rather than demanding a specific week, that is worth mentioning.
Combining scopes. One engagement covering web, API and external network shares overhead (setup, recon, reporting) across the lot.

How fixed-price scoping works

We do not do open-ended time-and-materials billing for standard engagements, because nobody budgets well against 'it depends'. The process:

A free scoping call. Half an hour where we ask about your application, environments, roles, objectives and deadlines.
A fixed quote within one business day. A specific price for a specific scope, with the number of testing days stated. If the scope changes later, the price changes transparently — but it never drifts on its own.
A free retest of fixed issues within 90 days. Remediation verification is part of the engagement, not an upsell, and you get updated reporting to show customers and auditors the findings were closed.

Fixed pricing also keeps the incentives honest: our job is to spend the scoped days finding as much as possible, not to find reasons to extend the meter.

Beware the pentest that costs too little

If one quote is AU$900 and the others are AU$9,000, the cheap one is not a bargain — it is a different product. Automated scan reports dressed as penetration tests are common at the bottom of the market, and they tend to surface exactly when an enterprise customer or auditor reads the report and rejects it. The re-test you then commission at full price makes the cheap option the most expensive one. Our guide to choosing a penetration testing company covers the red flags in detail.

FAQ

Why do penetration test quotes vary so much between vendors?

Day rates, tester seniority, how much of the work is genuinely manual, and whether delivery is in-house or subcontracted. Some variance is also products being quietly different — a vulnerability scan, a 'pentest lite', and a senior-led manual engagement can all arrive under the same label. Compare the number of testing days and a sample report, not just the bottom line.

Is a penetration test a one-off cost?

Treat it as an annual line item. Most organisations test at least yearly — auditors and enterprise customers expect a report less than 12 months old — plus after major changes. Budgeting it annually also gets you better scheduling and scope planning than scrambling when a deal depends on it.

Do you charge extra for retesting?

No. We retest fixed issues free within 90 days of the report and update your documentation to reflect what was remediated. Retesting is how the engagement actually delivers its value, so it belongs in the price.
