SOC 2 cost is the question that comes up first and gets the least straight answers. The audit fee is only one part of it, and often not the biggest. This article sets out what drives the cost for an Australian business, where the money actually goes, and how to keep the total down without weakening the report your customers will read.
Short answer
For an Australian business, the CPA firmโs audit fee is typically in the range of about A$15,000 to A$100,000 or more, depending on scope, the Trust Services Criteria included, Type I or Type II, and the size of the firm. Add the internal effort to build and run the controls, any readiness support, a penetration test, and tooling. A business that already runs ISO 27001 spends far less getting there than one starting from scratch.
Where the money goes
| Cost | What it covers | What moves it |
|---|---|---|
| Audit fee | The CPA firmโs Type I or Type II examination and report. | Scope, criteria, systems, locations, firm size, observation period. |
| Readiness and build | Defining scope, writing policies, setting up controls and evidence, and a readiness assessment. | How mature the current controls are; whether ISO 27001 is already in place. |
| Internal time | Staff running access reviews, change approvals, training and evidence collection. | How much is automated and how disciplined the routine is. |
| Technical testing | Penetration testing and vulnerability scanning the auditor will expect to see. | Number of applications and environments in scope. |
| Tooling | Compliance platforms, logging, endpoint and identity tools. | What is already licensed through existing cloud and identity providers. |
What drives the audit fee
- Type I or Type II. Type I checks control design on a single date. Type II tests operation over a period, usually three to twelve months, and costs more.
- Trust Services Criteria. Security is always included. Availability and Confidentiality are common additions; Processing Integrity and Privacy add more testing.
- Systems and locations. Each system, environment and site in scope adds testing.
- Subservice organisations. Heavy reliance on cloud and outsourced providers affects how the report is structured and what the auditor checks.
- The firm. Large firms price higher than mid-tier and specialist firms for similar scopes. Our guide to choosing a SOC 2 auditor covers what else to compare.
Published ranges for Australian firms give a sense of the spread: a small Type I with a specialist firm can start around A$15,000, mid-tier firms commonly quote tens of thousands for a Type II, and the largest firms quote into six figures for broad scopes. Treat any published range as a starting point and compare quotes on the same scope.
How to keep the total down
- Scope tightly. Include the service customers are actually buying and the systems that support it, not the whole company.
- Start with Security. Add other criteria only when customers ask for them.
- Build on ISO 27001. The risk assessment, policies, supplier controls, access management and internal audit already exist, so SOC 2 is mostly about evidence habits. Our ISO 27001 vs SOC 2 comparison explains the overlap.
- Run a readiness assessment first. Finding gaps before the observation period starts is far cheaper than finding exceptions in the report. See our SOC 2 readiness checklist.
- Use the tools already licensed. Cloud and identity platforms often produce most of the evidence. A compliance platform can help, but weigh it carefully; our article on compliance platforms covers the trade-offs.
How Streamline helps
We help Australian businesses scope SOC 2 sensibly, build the controls and evidence, and run the readiness assessment before the auditor arrives. We are independent of the CPA firm that issues the report, so we prepare you properly rather than marking our own homework, and we usually build on an ISO 27001 foundation so the same work supports both. Read about our SOC 2 readiness and advisory or talk to us about SOC 2.

Frequently asked questions
How much does a SOC 2 audit cost in Australia?
Published Australian ranges start at roughly A$15,000 for a small Type I with a specialist firm and run well into six figures for a broad Type II with a large firm. Scope, the number of Trust Services Criteria, the number of systems and the firm you choose drive most of the difference.
Is Type II more expensive than Type I?
Yes. A Type II tests how controls operated over a period, so the auditor samples evidence across months rather than checking design on one date. It also carries the internal cost of running the controls and keeping evidence for the whole period.
Do we have to buy a compliance platform?
No. Platforms can help with evidence collection and monitoring, but they are a cost, not a requirement. The CPA firm tests your controls, not your software. Weigh the subscription against how much of the evidence your existing tools already produce.
How often do we pay?
SOC 2 reports are usually renewed every year, so the audit fee recurs. The first year carries most of the build cost; later years are mainly the audit, the evidence effort and any changes to scope.
