5 Common privacy risks for businesses (and how to fix them)

When you’re busy running a business in regional Queensland, privacy risk can feel abstract compared to running day-to-day operations. But regulators don’t distinguish between metro and regional postcodes – your leadership team, board and internal IT team are on the hook, no matter your location.

Many businesses assume “IT” covers everything, while real data privacy risks remain unchecked.

Let’s break down five common privacy risk areas and how to address them before they can impact your organisation.

Why is privacy risk management critical for Australian organisations?

During the first half of 2025 alone, the OAIC was notified of 532 data breaches, with health, finance and government agencies heavily represented. Medical, NFP, education and professional services organisations are also often targeted.

For leadership teams still relegating privacy risk to the bottom of the to-do list, this is a wake-up call.

Across Australia, more organisations are prioritising privacy as a whole-of-business and board-level risk.

Effective privacy risk management means incorporating privacy into your broader governance, risk and compliance approach – a discipline you can support with a dedicated GRC service provider to align privacy controls with your everyday operations.

What are the most common privacy risks affecting businesses in Australia?

Rather than standing out as glaring concerns, privacy issues often creep through everyday habits and blind spots. Some of the most common privacy risks impacting Australia business typically fall into five patterns:

• poor data handling practices
• third-party vendor risks
• access mismanagement
• inadequate privacy policies and training
• insufficient data breach response plans.

Understanding these risk areas is the first step toward remedying them.

Risk 1: Poor data handling practices

How do poor data handling practices become a privacy risk for businesses?

Many businesses underestimate how everyday data practices (like storing client or patient records in email inboxes, spreadsheets or USB drives) can quickly create serious exposure points.

Ad-hoc data storage

When sensitive personal or health information is scattered across unsecured emails, shared drives, spreadsheets or removable drives, it becomes far more vulnerable to accidental disclosure or loss – especially if devices go missing or credentials are compromised.

The Office of the Australian Information Commissioner (OAIC) has repeatedly warned that emailing personal data is a leading cause of human-error breaches.

Lack of data minimisation & unclear consent

Under the Privacy Act 1988 and its Australian Privacy Principles (APPs), organisations must only collect personal information that is “reasonably necessary” for their functions, and must be clear about how that data will be used.

If your organisation lacks robust consent procedures or data-minimisation policies, you may over-collect or retain data indefinitely, increasing compliance risks.

These concerns are especially common for smaller organisations in medical, NFP or professional-services sectors that may lack formal records-management or privacy governance frameworks.

For regional or smaller organisations without a mature privacy/risk function, an experienced privacy advisory service provider can help you map data storage, assess data lifecycles and implement policies to reduce unnecessary exposure.

Risk 2: Third-party vendors handling sensitive information

What privacy risks arise when third-party vendors handle sensitive information?

Many organisations don’t realise that providing system access or handing over data to third-party vendors can multiply risk.

Risks from EMR systems, cloud CRMs and outsourced IT

If you use external electronic medical record (EMR) software, cloud-based CRMs or outsource IT support, sensitive records can leave your direct control. If vendors misconfigure storage or lack robust security, breaches can expose personal or health data, even if your internal systems are secure.

Offshore data storage considerations

Some vendors store or back up data overseas. This can create complexity around jurisdiction, foreign laws with weaker data protections, different security standards and potential unauthorised access by foreign entities.

Compliance frameworks: ISO 27001, SOC 2, NIST

Effective vendor risk management requires vendors to meet recognised security standards and follow continuous monitoring.

Consider getting support with a formal vendor risk assessment to confirm if third party providers meet required standards (at present and over time).

Risk 3: Access mismanagement

Why is staff access mismanagement one of the biggest privacy liabilities?

Even with secure systems and vendor controls, mismanaged staff access is one of the most common paths for privacy failures. Here’s why.

Over-permissioning and shared logins

When staff have more permissions than needed or share generic logins, it becomes impossible to trace who accessed what — opening doors for accidental or malicious data exposure.

No IAM policies

Small organisations, especially clinics or professional-services firms, often lack formal identity and access management (IAM) frameworks. This means outdated permissions, old accounts or excessive privilege may go unnoticed.

Lacking modern standards: Zero trust, IAM, least-privilege access

Adopting frameworks such as the Australian Signals Directorate’s restricted administrative privileges (zero trust, IAM, least-privilege access) is best practice for ensuring staff only access what’s needed and reducing the risk of potential breaches.

Risk 4: Inadequate privacy policies

How do inadequate privacy policies and training put organisations at risk?

Privacy policies can be useful, but they lack effectiveness if they’re outdated, generic or staff don’t understand how to apply it. Weak policy plus poor training can create some of the biggest privacy risks.

Outdated templates vs. sector-specific policies

Many organisations copy standard templates – but these are often ill-fitting for the realities of medical, NFP or education organisations. Generic privacy policy templates can fail to comply with all applicable laws, match your data practices, reflect your actual operations and stay current as laws change.

Human error as the leading cause of breaches

According to the latest Office of the Australian Information Commissioner (OAIC) data, human error is one of the leading cause of breaches, most recently accounting for 37% of data breaches reported.

It just goes to show how easily an incorrect email recipient or mis-filed document can trigger a privacy incident when teams lack training or improper controls are in place.

Need for privacy governance, compliance culture & training

Compliance with the Privacy Act 1988 and its principles (data minimisation, consent, storage, disposal, etc.) relies on embedding privacy awareness in everyday operations.

For organisations without a mature compliance function, consider engaging a reputable external GRC provider to develop a structured governance, risk and compliance framework and embed GRC into your culture.

Risk 5: Insufficient data breach response plans

What happens when a business doesn’t have a clear data breach response plan?

Even with strong prevention measures, data breaches can still happen. And without a clear, tested response plan, the consequences can be far worse.

The regulatory, financial and reputational consequences of delay response

Under the Notifiable Data Breaches scheme (NDB Scheme), organisations covered by the Privacy Act must notify affected individuals and the OAIC when a breach is likely to cause serious harm.

Without a response plan in place, response delays can amplify harm and lead to legal, financial and reputational fallout.

Lack of clarity across IT, legal, operations and leadership

Strong response plans feature clearly defined roles for different departments, including:

• Who assesses the breach?
• Who communicates externally?
• Who handles containment?
• Who manages evidence?

Without that clarity, response efforts can stall or overlap, amplifying risk.

Effective incident response planning and containment are critical. The Australian Cyber Security Centre (ACSC) emphasises that written, tested incident response plans help organisations contain and manage cyber security incidents and data breaches before they can escalate.

Developing a sound data breach response plan as part of a broader GRC or privacy risk management program can help your organisation prepare well.

Frequently asked questions

What is the fastest way to reduce privacy risk in a small business?

The fastest way to reduce privacy risk in a small business is to focus on quick, high-impact actions that address common vulnerabilities. Begin with a simple privacy review to understand how personal data is collected, stored, and shared, and remove anything unnecessary. Restrict access to sensitive information, enable multi-factor authentication, and keep all software up to date. For more comprehensive actions and tailored recommendations, consult a privacy expert.

How do I know if my organisation is breaching the Australian Privacy Act?

Organisations that are over-collecting data, unclear about consent, storing information indefinitely, or don’t have the capacity to confidently respond to access requests or breaches are likely in breach of OAIC regulations.

What personal data are businesses not allowed to collect?

Organisations must not collect sensitive or personal information unless it is reasonably necessary for operations and proper consent is obtained.

How much can a privacy breach cost in Australia?

The cost of a privacy breach can vary. Regulatory penalties, legal fees, remediation, lost revenue and lasting reputational damage often far exceed the cost of prevention.

What is the simplest privacy framework for small organisations to follow?

The Australian Privacy Principles (APPs) provide a practical baseline for most small and mid-sized organisations to follow.

How can a privacy advisory service help address these risks?

A privacy advisory service can assess how data is collected, used, shared and governed throughout your organisation. They can provide privacy risk assessments, support with policy and consent modernisation, manage vendor risk and help embed privacy with everyday practices.

For boards and senior leaders without in-house privacy capability, privacy advisory services are an invaluable way to gain practical assurance, and translate legal and regulatory expectations into stronger controls.

Engage expert privacy advisory services to move from uncertainty to accountability and confidence in how your organisation’s privacy risk is managed.

What should business leaders do next?

Managing privacy risk doesn’t have to be complex. A simple readiness check starts with three questions:

• Do you know where sensitive data lives?
• Who can access it?
• How you would respond if a breach occurred tomorrow?

For leadership teams and boards, make privacy accountability a whole-of-business priority.
