Security Policy Template Australia: What to Include (2026)

A broker renewing your cyber insurance asks for "your security policy." A big customer's vendor questionnaire has a line for it. Neither explains what that actually means, and you're left staring at a blank page wondering what counts.

Here's the short version: a security policy is a written statement of the controls your business runs and who's responsible for them. Below is what an Australian small-business version needs to cover, what a generic template won't do for you, and a faster path than starting from a blank Word document.

Why this request landed on your desk

It's rarely random. Three things tend to trigger it:

1. Insurance renewal. Cyber insurance proposal forms grow more detailed each year, and "do you have a written security policy?" is now a common line item.
2. A bigger customer's due diligence. Once your revenue depends on a larger client, their procurement team runs a security questionnaire before signing.
3. The Essential Eight became the reference point. The Australian Signals Directorate's Essential Eight is the baseline most Australian guidance points to, so "security policy" questions increasingly assume it.

None of this means you're in trouble. It means someone wants to see the rules written down instead of taking your word for it.

What an Australian security policy actually needs to cover

Skip the padding. A policy that actually answers a broker's or customer's question covers five things:

• Scope. Who and what it applies to: staff, contractors, every device used for work.
• Roles and responsibilities. Who owns the policy (usually the business owner), and what staff are expected to do day to day.
• The controls themselves. This is the substance. Most Australian guidance, including cyber insurer questionnaires, maps back to the ACSC Essential Eight Maturity Model: application control, patching, restricted macros, multi-factor authentication, restricted administrative privileges, and regular, tested backups among them. Writing a section per control, stating honestly where each one actually stands, is most of what a reviewer wants to see.
• What happens when something goes wrong. Even a short pointer to an incident response process matters here, because "we have a policy but no plan" is a gap reviewers notice.
• A review date. Once a year, or whenever something material changes. A policy with no review date reads as something nobody has looked at since it was written.

What a generic template won't do for you

Search for a security policy template and you'll find two kinds: a free Word document covering generic best practice, or a paid one drafted by a law firm. Both are a reasonable starting point. Neither reflects what your business actually does, and neither knows whether you've actually turned MFA on, or whether your last backup restore was ever tested.

That gap matters more than it sounds. A policy that claims controls you don't actually have is worse than no policy at all, because the next step for an insurer or reviewer checking your answers is usually a direct question about your real setup. The safest policy is the honest one: it describes what you run today, and your remediation plan for the rest. That's also the harder document to produce from a template, because a template has no way of knowing what "today" looks like for your business.

A section-by-section outline you can draft from today

You can start writing this afternoon. Here's the structure:

1. Purpose. One paragraph: why the business has a security policy and what it protects.
2. Scope. All staff and contractors, any device used for work.
3. Roles. Who approves the policy, who's responsible for each control.
4. Controls. A short section per control you run: application control, patching, restricted macros, user application hardening, admin access, OS patching, MFA, backups. Say what you actually do, not what the textbook says to do.
5. Incident response. A pointer to your plan, or a short outline if you don't have a separate one yet.
6. Review. Who owns this document and the date it's next reviewed.

That's the whole shape. The work isn't length, it's accuracy.

The faster way: generated from your own self-assessment

Writing all of that from scratch, and keeping it honest about what you actually have in place, is the slow part. There's a shorter path: our free Essential Eight self-assessment takes about 20 minutes, and the paid document pack generates an Information Security Policy from your actual answers, alongside four further policies covering access control, patch management, backup and recovery, and acceptable use, plus an Incident Response Plan and a prioritised remediation roadmap for anything the assessment finds short.

It is not a certification, audit, or guarantee of security or insurance outcomes, and it won't tell an insurer your business is risk-free. The documents reflect your self-assessment, not an independent review, and they aren't legal or insurance advice. What they do is turn "do you have a written security policy?" into a document you can actually hand over, built from what your business is doing today rather than a stranger's generic template.

If you've already looked at the AI side of this, our AI use policy template covers the same ground for that specific control, and does your business need an AI policy at all is worth a read first if you're not sure.

FAQ

Is a security policy legally required in Australia? No single law requires a stand-alone security policy for most small businesses. The pressure is indirect: insurers and big customers increasingly ask for one, and the Privacy Act's reasonable-steps expectation means you need to be able to show how information is actually protected, policy or not.

What should a small business security policy include? At minimum: scope, who's responsible for what, the controls you run (commonly the ACSC Essential Eight: MFA, patching, backups, restricted admin access and the rest), and a review date. Most insurer and vendor questionnaires are really asking whether these things are written down and current, not whether the document is long.

How is a security policy different from an Essential Eight assessment? The assessment measures where your controls actually stand, control by control. The policy is the written statement of what you commit to doing. They work together: a policy with nothing backing it is paperwork, and an assessment with no policy has nothing written down for a broker to read.

Do I need a lawyer to write a security policy? Not for the baseline document most small businesses need. A security policy describing your technical controls is different from a contract or a legal obligation. If your business handles unusually sensitive data, health or financial records for example, it's worth having a professional review the final draft.
