Quick answer: A plant and equipment register is a WHS document that records every significant piece of plant and equipment in your workplace, along with its maintenance history, inspection and test dates, registration details for registrable items, and operator licence requirements. It helps you meet your duty of care under Australian WHS law and ensures plant is safe to use.

If you operate a business that uses machinery, vehicles, powered tools, or pressure equipment, you are required under Australian WHS legislation to manage the risks associated with that plant. A plant and equipment register is the document that makes that management visible, trackable, and auditable.
This guide explains what a plant and equipment register is, what it needs to record, why it matters, and how it differs from a simple asset register.
What is a plant and equipment register?
A plant and equipment register is a centralised WHS record that lists every significant piece of plant and equipment your business owns, leases, or manages — and captures the safety-critical information associated with each item.
Under the Model Work Health and Safety Act 2011 and associated Model WHS Regulations, PCBUs (persons conducting a business or undertaking) must manage risks arising from plant. This includes ensuring plant is designed, manufactured, used, and maintained so that it does not create a risk to health and safety. The plant register is the primary document that demonstrates you are meeting those obligations.
"Plant" under Australian WHS law covers a wide range — from hand tools and ladders to forklifts, cranes, boilers, pressure vessels, excavators, and elevating work platforms. Not every item needs to be on your register, but anything that poses a meaningful risk — or is classified as registrable plant — must be included.
What a plant and equipment register records
A well-maintained plant and equipment register captures the following for each item:
Item description
The common name and type of equipment — for example, "Scissor Lift — Electric" or "Air Compressor — Reciprocating." This should be descriptive enough that anyone reading the register can identify the item without ambiguity.
Make, model, and serial number
The manufacturer name, model designation, and unique serial number. This information is essential for sourcing the correct operator manuals, confirming inspection intervals, and verifying manufacturer specifications — particularly after an incident.
Registration number (for registrable plant)
Certain categories of plant must be registered with the relevant state or territory WHS regulator before they are used. Your register must capture the registration number, the issuing regulator, and the registration expiry date for every registrable item. Allowing a registration to lapse while continuing to use the plant is a breach of the WHS Regulations and can attract significant penalties.
Service and maintenance dates
A record of every scheduled and unscheduled service — including the date the service was performed, who performed it, and what was done. This creates an auditable trail and helps you identify items that are overdue for service before they become a hazard.
Inspection and test dates
Many plant items are subject to mandatory periodic inspections or testing — for example, electrical testing and tagging, pressure vessel inspections, load testing for cranes and hoists, or fall-arrest equipment inspections. Your register should record the date of the last inspection, who conducted it, the outcome, and the date the next inspection is due.
Risk assessment reference
A reference to the risk assessment or safe work method statement (SWMS) that applies to the item. This links your plant register to the rest of your WHS management system and confirms that the hazards associated with operating the equipment have been formally assessed.
Operator licence requirements
Some plant can only be operated by a person who holds a specific high-risk work (HRW) licence — for example, forklifts, cranes, pressure equipment, and elevated work platforms. Your register should record what licence class is required to operate the item. This prevents unlicensed operation and supports your induction and training planning.
Why the plant and equipment register matters
Maintenance and safe operation
Plant that is not maintained in accordance with manufacturer specifications and WHS requirements creates a foreseeable risk of injury. The register is your system for ensuring nothing falls through the cracks — it tells you at a glance when the next service is due, who is responsible for arranging it, and whether any items are currently out of service.
Registrable plant obligations
For plant that must be registered with a WHS regulator, the consequences of failing to register — or allowing a registration to lapse — are serious. A plant register helps you track each registration's expiry date and ensure renewals are completed on time. This is one of the most common compliance failures identified during WHS inspections of workplaces that use heavy plant or pressure equipment.
Scheduled inspections and testing
Many inspections are legally required at set intervals — they are not optional. A register that tracks inspection due dates helps you schedule them in advance rather than react after the fact. It also provides documented evidence, which matters when you are responding to an incident investigation, a regulator inquiry, or a principal contractor's pre-qualification requirements.
How a plant register differs from an asset register
These two documents are often confused — sometimes the same spreadsheet is used for both purposes — but they serve entirely different functions.
An asset register is an accounting and financial document. It records what the business owns, when it was purchased, its purchase price, its depreciation rate, and its current book value. It is used for financial reporting, insurance purposes, and tax compliance.
A plant and equipment register is a WHS document. It exists to protect workers. It records safety-critical information: registration numbers, inspection dates, service history, risk assessments, and operator licence requirements. It is used to manage risk, demonstrate duty of care, and satisfy WHS regulators.
An asset register does not replace a plant register, and a plant register is not a substitute for an asset register. You need both — but for different reasons.

Sample register rows
The following example shows how two common plant items might appear in a plant and equipment register.
| Item Description | Make / Model | Serial No. | Registration No. | Registration Expiry | Last Service | Next Service Due | Last Inspection | Next Inspection Due | Risk Assessment Ref | Licence Required |
|---|---|---|---|---|---|---|---|---|---|---|
| Scissor Lift — Electric (10 m) | JLG / 3246ES | SN-JLG-00442 | EWP-QLD-29841 | 30 Nov 2026 | 14 Mar 2026 | 14 Sep 2026 | 14 Mar 2026 | 14 Sep 2026 | RA-PLANT-007 | HRW Licence — EWP (Class WP) |
| Air Compressor — 60 L Reciprocating | Ingersoll Rand / SS3L3 | IR-2024-08811 | PV-NSW-50123 | 15 Jul 2026 | 01 Feb 2026 | 01 Aug 2026 | 01 Feb 2026 | 01 Aug 2026 | RA-PLANT-012 | None |
In a working register, each row would also include the responsible person for scheduling services and inspections, the item location, and its current status (in service, out of service, decommissioned).
Linking your plant register to your pre-start checks
The plant register gives you the big picture — it tells you what plant you have, when it was last inspected, and whether it is due for service. But it does not replace day-to-day operational checks.
A plant pre-start checklist is the document your operators complete before using a plant item each day or each shift. It captures visible defects, fluid levels, safety devices, and operational checks that the operator can see and test before starting work. Where the register tracks scheduled maintenance and formal inspections, the pre-start checklist picks up issues that develop between those events.
These two documents work together. If a pre-start check identifies a defect, that information should flow back into the register — either as an out-of-service notation or as a trigger for an unscheduled service.

Frequently asked questions
What is the difference between a plant register and an asset register?
An asset register tracks the financial value and ownership of business property for accounting purposes. A plant and equipment register is a WHS document — it records safety-critical information such as registration numbers for registrable plant, inspection and test dates, operator licence requirements, service history, and risk assessment references. An asset register does not replace a plant register for WHS purposes. See our guide on plant register vs asset register for a full comparison.
What plant items need to be registered in Australia?
Under the Model WHS Regulations, certain plant items must be registered with the relevant state or territory WHS regulator before use. These are known as "registrable plant" and include pressure vessels, cranes, forklifts, boilers, elevating work platforms, and amusement devices. Each jurisdiction publishes its own list. Your plant register should record the registration number and expiry date for every registrable item you own or manage.
Who is responsible for maintaining the plant and equipment register?
The person conducting a business or undertaking (PCBU) is ultimately responsible for ensuring the register is maintained. In practice, day-to-day management is often delegated to a safety officer, facilities manager, or operations manager. Whoever manages it must ensure the register is kept up to date, reflects current inspection and service records, and captures any changes to plant status — such as decommissioning, sale, or transfer to another site.
How often should the plant and equipment register be updated?
Your plant register should be updated whenever a new item is acquired, whenever a scheduled service or inspection is completed, when a registration is renewed, when an item is decommissioned or disposed of, and after any incident involving the plant. At a minimum, review the entire register annually to check that all scheduled inspections, services, and registrations are current and that no entries are out of date.
