Quick answer: WHS documents must be reviewed on a schedule and updated whenever legislation changes, work changes, an incident occurs, or new plant or chemicals are introduced. A document register, clear ownership, and version control turn document management from a reactive task into a repeatable process.
Last reviewed: June 2026 by the BlueSafe Technical Team. Reflects current Australian WHS laws and regulations.
A WHS document is only useful if it reflects the way work is actually done and the law as it currently stands. A procedure written three years ago for a task that has since changed is not a safety document — it is a liability. Keeping WHS documents current is one of the most overlooked aspects of safety management, and one of the first things a regulator or auditor will check.
Why currency matters
Legislation and regulations change
Safe Work Australia regularly updates the Model WHS Regulations, Codes of Practice, and associated guidance. State and territory regulators also issue updates and amendments that affect specific industries or activities. If your documents reference superseded requirements, you may be directing workers to follow outdated controls, using incorrect risk ratings, or failing to meet obligations that have since been strengthened.
Common areas where legislation shifts include: silica and crystalline silica exposure standards, psychosocial hazard obligations, high risk construction work requirements, plant registration and inspection rules, and hazardous chemicals classification and labelling under the GHS system.
Work changes over time
A risk assessment or SWMS written for a specific task, site, or piece of equipment becomes unreliable the moment any of those variables change. Businesses that grow, take on new work types, move locations, or change their plant and equipment without updating their documents create a gap between what is written and what is actually happening.
This matters because the defence of due diligence depends in part on having documentation that reflects reality. A document that describes a process no longer used in that way does not demonstrate control — it demonstrates that the system is not being maintained.
Audits and tenders
Many contracts, particularly in construction, resources, and government, require current WHS documents as a condition of engagement. Auditors and client prequalification teams are trained to check review dates, version histories, and whether the content aligns with the actual work scope. Submitting a SWMS or management plan with a review date three years old is a red flag that often results in failed prequalification or delayed contract start.
Regulator inspections also focus on document currency. An inspector who sees a risk assessment with an old date, or a procedure that references plant no longer on site, has grounds to question whether the broader safety system is being actively managed.
Incidents and near misses
When a notifiable incident or near miss occurs, it is usually a sign that something in the control framework did not work as intended. That almost always requires a review of the relevant documents — not just to update them, but to understand whether the control was correctly specified, whether workers were trained in it, and whether it was being followed in practice.
Failing to update documents after an incident — and failing to record that the review occurred — is one of the most common findings in incident investigations.
Setting up a document review schedule
A review schedule is a planned calendar of when each document will be assessed for currency and accuracy. Without a schedule, document reviews happen only when someone notices a problem, which is often too late.
A practical review schedule assigns every WHS document one of the following review frequencies:
| Review frequency | Applies to |
|---|---|
| Every 6 months | SWMS for high-risk construction work, documents for tasks with high injury rates, chemical registers and SDS |
| Annually | Risk assessments, most SWMS, safe work procedures, WHS policy, consultation processes, emergency plans |
| Every 2 years | Lower-risk procedures with stable activities, training matrices, contractor management forms |
| On trigger only | Documents specific to a single project, site-specific documents, documents for decommissioned tasks |
The schedule should be recorded in your document register. At the start of each review period, the nominated document owner receives a reminder and is responsible for completing the review or escalating it if the work is no longer performed.
A review does not always mean the document changes. It means the document has been checked, confirmed as current, and the review has been recorded with a new date and reviewer name.
Version control and the document register
Version control
Version control is the practice of tracking changes to documents over time so that the current version is always clearly identified and previous versions are not confused with the current one.
A simple version control system uses:
- a version number (e.g. Version 1.0, 1.1, 2.0) or revision date in the document header or footer;
- a change summary section that notes what was altered and why;
- an approval date and approver name;
- a clear label on superseded versions (e.g. "Archived — superseded by Version 2.1, June 2026").
Without version control, it is easy for workers to use an old version of a procedure because it is saved locally on a device or printed and filed in a site folder. That risk increases significantly when documents are stored in shared drives with no clear naming convention.
The document register
A document register is a single controlled list of all current WHS documents. It is the master reference for what exists, who owns it, and when it was last reviewed.
A basic document register includes:
| Field | Purpose |
|---|---|
| Document name | Identifies the document |
| Document type | Policy, procedure, SWMS, form, register, plan |
| Version number | Confirms current version |
| Date last reviewed | Shows when the last review was completed |
| Next review due | Triggers upcoming reviews |
| Owner | The person responsible for the document |
| Location | Where the current version is stored |
| Status | Current, under review, archived, superseded |
The document register should be reviewed as part of your annual WHS system review. Any documents past their review date should be escalated immediately.
Triggers for immediate review
Scheduled reviews keep documents broadly current. Trigger-based reviews address changes that cannot wait for the next scheduled date.
New or changed work activities. Any time the business takes on a new type of work, changes a process significantly, or moves to a new site, the relevant documents should be reviewed and updated before work begins. A SWMS written for one site configuration should not be used at a different site without review.
Incidents and near misses. After any notifiable incident or near miss, the SWMS, risk assessment, or safe work procedure for the relevant task should be reviewed as part of the investigation process. The corrective actions from the investigation should be reflected in the updated document.
Legislative or regulatory changes. When Safe Work Australia or a state/territory regulator amends the WHS Regulations, issues a new or revised Code of Practice, or changes an exposure standard, any documents that reference those requirements should be reviewed. Subscribing to regulator update notifications makes this easier to track.
New plant or equipment. When new plant is introduced, or existing plant is modified or repaired, any SWMS, inspection checklist, or procedure that covers that plant must be reviewed. The current SDS and any manufacturer instructions should be incorporated.
New hazardous chemicals. When a new chemical is introduced to the workplace, the chemical register must be updated, the relevant SDS obtained and filed, and any risk assessments or work procedures that involve chemical use reviewed.
Contractor or worker feedback. If workers or supervisors identify that a procedure no longer matches how work is done in practice, that is a trigger for review. Workers are often the first to notice when a document has drifted from reality.
Assigning ownership
A document with no owner is a document that does not get reviewed. Every WHS document should have a single nominated owner who is responsible for:
- initiating the review at the scheduled date or when a trigger occurs;
- completing or coordinating the review;
- recording the review outcome in the document register;
- approving the updated version;
- communicating changes to affected workers.
Ownership should be by role, not by name. If ownership is assigned to an individual, it needs to be transferred when that person leaves. If it is assigned to a role — "Site Manager", "Safety Advisor", "Operations Manager" — the responsibility transfers automatically when the role changes hands.
For businesses with a large document library, a simple ownership matrix listing each document and its owner role helps during annual system reviews and management audits.
Software vs manual systems
Manual systems
A manual document management system — using shared drives, printed registers, and calendar reminders — is workable for small businesses with a limited number of documents. The risks are version control drift (old versions accumulating in shared folders), missed review dates without automated reminders, and difficulty generating audit evidence quickly.
Manual systems require more discipline from document owners and more active oversight from managers. They work best when someone is specifically responsible for managing the system and has time to do it consistently.
Software systems
Safety management software adds value by:
- automating review reminders at scheduled dates or trigger events;
- restricting editing to authorised users and recording who made changes;
- maintaining version history automatically;
- providing a dashboard view of outstanding reviews and overdue documents;
- generating a current document register on demand for audits and tenders.
The same principles apply to both approaches. Software does not replace the need for scheduled reviews, clear ownership, and trigger-based updates. It makes those processes easier to run consistently and produces better audit evidence.
Blue Safe Online provides a platform where WHS documents can be stored, reviewed, and managed with version control and review tracking built in, reducing the overhead of manual document management for businesses of any size.

Frequently asked questions
How often should WHS documents be reviewed?
Most WHS documents should be reviewed at least annually. Documents covering high-risk work or frequently changing activities should be reviewed every six months. Certain triggers — an incident, a change in work, new plant or chemicals, or a legislative update — require an immediate review regardless of the scheduled date.
Who is responsible for keeping WHS documents current?
The PCBU carries ultimate responsibility. In practice, ownership is delegated to a nominated role for each document — usually a manager, supervisor, or safety advisor — who initiates reviews, updates content, and records changes in the document register.
What is a WHS document register?
A WHS document register is a controlled list of all safety documents held by the business. It records the document name, version, date last reviewed, owner, review due date, and storage location. It allows the business to see at a glance which documents are current and which are overdue for review.
Does software make WHS document management easier?
Yes, particularly for businesses managing more than a handful of documents. Safety management software automates reminders, enforces version control, and generates audit trails. The same principles — scheduled reviews, ownership, and trigger-based updates — apply whether the system is digital or paper-based.
