Copilot Data Governance Policy Template for Australian Organisations

A Copilot Data Governance Policy is not optional for Australian organisations that have deployed or are planning to deploy Microsoft 365 Copilot — it is a Privacy Act compliance obligation. This article provides a complete policy template you can adapt, along with the rationale for each clause and guidance on the Australian regulatory context that drives the requirements.

Why a Standalone Copilot Policy Is Necessary

Standard IT acceptable use policies were written for deterministic systems: you click a button, a defined action occurs. Microsoft 365 Copilot is a generative AI system that aggregates, synthesises, and presents information from across your Microsoft 365 estate in ways that are not always predictable or auditable in real time.

Three Copilot-specific risks that standard IT policies do not address:

Data aggregation across permission boundaries. Copilot can synthesise information from multiple documents that a user can individually access but may not have intended to combine. An employee with access to HR data and financial data can, without policy controls, ask Copilot to correlate salary information with performance reviews — creating a new data product that no individual document authorised.

AI-generated content presented as authoritative. Copilot outputs are often presented in a confident, authoritative tone. Users who rely on Copilot-generated summaries for compliance decisions, legal matters, or client communications may be acting on incorrect information without realising it.

Prompt injection and data exfiltration vectors. Malicious content embedded in documents that Copilot accesses can manipulate Copilot's responses to exfiltrate data or mislead users — a risk category that does not exist in traditional IT environments.

For the technical controls that underpin this policy, particularly sensitivity label configuration, see the Pillar guide which covers the Microsoft Purview information protection architecture in detail.

Policy Template: Microsoft 365 Copilot Data Governance Policy

The following template is structured for an Australian private sector or government organisation. Replace bracketed placeholders with your organisation's specific details.

1. Purpose and Scope

1.1 Purpose

This policy establishes the governance framework for the use of Microsoft 365 Copilot within [Organisation Name]. It defines acceptable use boundaries, data handling obligations, access controls, and audit requirements to ensure that Copilot deployment complies with the Australian Privacy Act 1988, the Privacy Amendment (Notifiable Data Breaches) Act 2017, and [Organisation Name]'s information security obligations.

1.2 Scope

This policy applies to:

• All employees, contractors, consultants, and volunteers who access Microsoft 365 Copilot under [Organisation Name]'s Microsoft 365 tenant
• All Microsoft 365 applications in which Copilot functionality is enabled, including but not limited to Word, Excel, PowerPoint, Outlook, Teams, and Copilot Chat
• All data processed by Copilot, regardless of where that data is stored within the Microsoft 365 environment

1.3 Policy Owner

This policy is owned by [CISO / CIO / Head of IT Security]. It is reviewed every six months or immediately following any material change to Microsoft Copilot's data processing capabilities.

2. Regulatory Context

2.1 Australian Privacy Act 1988

Microsoft 365 Copilot processes personal information as defined by the Privacy Act when it accesses documents, emails, or Teams conversations containing information about identifiable individuals. This policy implements controls required under the following Australian Privacy Principles:

• APP 6 (Use or disclosure of personal information): Copilot must not be used to disclose personal information for a purpose other than the primary purpose for which it was collected
• APP 11 (Security of personal information): Technical and administrative controls must prevent unauthorised access to or disclosure of personal information through Copilot
• APP 13 (Correction of personal information): AI-generated outputs containing personal information must not be treated as authoritative without verification against source records

2.2 Notifiable Data Breaches Scheme

Any incident where Copilot surfaces personal information to an unauthorised person, or where Copilot-assisted data aggregation results in the creation of a new personal information record that was not authorised, must be assessed against the Notifiable Data Breaches (NDB) threshold within 30 days of discovery.

3. Data Classification and Copilot Access Controls

3.1 Sensitivity Label Hierarchy

[Organisation Name] classifies information using the following sensitivity labels, configured in Microsoft Purview:

3.2 Confidential Data Access Rules

Copilot access to Confidential-labelled items is permitted only when:

• The user has been granted explicit access to the relevant SharePoint site or document library
• The Copilot interaction is within the same Microsoft 365 session and tenant
• The output is not shared externally or pasted into an externally-shared document

3.3 Prohibited Data Uses

Copilot must not be used to:

• Process or summarise documents labelled Highly Confidential (enforced technically via Purview data boundary controls)
• Generate content that includes personal information for purposes other than the original collection purpose
• Create new aggregated datasets from personal information without explicit authorisation from the Privacy Officer
• Assist in activities that would constitute a breach of legal professional privilege

4. User Tiers and Acceptable Use

4.1 General Users

All employees with Copilot licences are General Users unless otherwise designated. General Users may:

• Use Copilot to draft, summarise, and edit documents labelled Public or Internal
• Use Copilot Chat for business productivity tasks that do not involve Confidential or Highly Confidential content
• Use Copilot in Teams meetings to generate meeting summaries, provided no Highly Confidential information is discussed

General Users must not:

• Ask Copilot to retrieve, aggregate, or analyse personal information of other employees or customers beyond what is required for their role
• Share Copilot-generated outputs externally without review by a human subject matter expert
• Use Copilot to process information outside the scope of their normal job function

4.2 Power Users

Power Users are employees authorised to use Copilot for Confidential-labelled data. Designation as a Power User requires:

• Line manager approval
• Completion of the [Organisation Name] Copilot Governance Training module
• Annual recertification

4.3 Restricted Users

Users who handle Highly Confidential information as part of their role — including Legal, People and Culture (for sensitive HR matters), and Executive Leadership — may have Copilot access restricted or disabled entirely for specific workloads. IT Security will configure per-user or per-group Copilot access restrictions in the Microsoft 365 admin centre.

4.4 Administrators

Microsoft 365 administrators who configure Copilot settings must:

• Document all configuration changes in the IT change management system
• Not use administrative access to extend Copilot's data access beyond what this policy permits
• Review Copilot audit logs monthly and report anomalies to the CISO

5. AI-Generated Content Standards

5.1 Disclosure Requirements

Employees must disclose when content submitted to clients, regulators, or external stakeholders was substantially generated or drafted by Copilot. "Substantially" means more than 50 percent of the final content originated from a Copilot output.

5.2 Verification Obligation

Copilot-generated content must not be used for:

• Legal advice or legal documents without review by a qualified legal practitioner
• Financial reports or statements without review by a qualified financial officer
• Medical or health information without review by a qualified health practitioner
• Regulatory submissions without verification against primary source data

5.3 Retention of AI Outputs

Copilot interaction logs are retained for 90 days in Microsoft Purview Audit. Employees must not use Copilot to create records that are required to be retained under [Organisation Name]'s Records Management Policy and assume that Copilot logs constitute the retention copy.

6. Security and Incident Reporting

6.1 Mandatory Reporting Obligations

Users must report the following incidents to the IT Security team within 24 hours:

• Copilot surfacing data that the user believes they should not have access to
• Copilot generating outputs that appear to contain personal information of individuals not relevant to the task
• Any Copilot interaction where the output is inconsistent with expected behaviour in a way that suggests data leakage or manipulation

6.2 Incident Response

Upon receiving a Copilot-related incident report, IT Security will:

1. Disable Copilot access for the affected user within four hours
2. Extract relevant audit logs from Microsoft Purview within 24 hours
3. Conduct an initial assessment of whether personal information was involved within 48 hours
4. If personal information was involved, initiate the NDB assessment process within 72 hours

7. Training and Awareness

All users must complete Copilot Governance Training before Copilot access is enabled. Training covers:

• What Copilot can and cannot access in your Microsoft 365 environment
• How sensitivity labels control Copilot behaviour
• Acceptable use boundaries under this policy
• How to report a Copilot-related incident

Training must be renewed annually. Completion is tracked in [LMS / HR System].

8. Policy Compliance and Enforcement

Breaches of this policy may result in:

• Suspension of Copilot access pending investigation
• Disciplinary action up to and including termination of employment
• Reporting to relevant regulatory bodies where the breach constitutes a privacy violation under the Australian Privacy Act

Implementing This Policy in Your Organisation

A policy document is only effective when it is backed by technical controls, training, and an audit programme. The practical implementation order is:

1. Technical controls first — configure sensitivity labels and Copilot data boundary controls before publishing the policy (a policy that cannot be enforced technically creates false assurance)
2. Training before access — gate Copilot licence assignment on completion of the training module
3. Policy publication — distribute the policy and require acknowledgement via your HR system
4. Audit programme — schedule monthly Copilot audit log reviews for the first quarter, then move to quarterly

To understand where your organisation currently sits against these requirements, the free Copilot Governance Assessment provides a structured maturity benchmark across technical controls, policy, training, and audit dimensions.

Keeping the Policy Current

Microsoft releases major Copilot capability updates multiple times per year. Each update has the potential to change Copilot's data access behaviour, introduce new features that interact with sensitivity labels, or enable new data processing scenarios that are not covered by your current policy.

Assign a named owner — typically the CISO or IT Security Manager — to monitor the Microsoft 365 Message Centre for Copilot-related update announcements and trigger a policy review whenever a material change is identified.

The six-monthly review cycle specified in Section 1.3 of this template is a minimum. Organisations in regulated sectors — financial services, healthcare, legal — should review this policy quarterly given the pace of regulatory development around AI governance in Australia.
