JSA vs SWMS: The Difference and When You Need Each

The short answer

A SWMS is required by law before high risk construction work starts. If your work is on the list, you need one.
A JSA is a risk assessment tool for any task. WorkSafe Victoria says it is not required under legislation, but your site, client or employer may require one.
A JSA does not replace a SWMS. WorkSafe Victoria says a SWMS is not the same as a risk assessment or a JSA.

What is a SWMS?

WorkSafe Victoria describes a SWMS as a document that sets out the high risk construction work to be done, the hazards and risks that arise from it, and the measures put in place to control those risks. Safe Work Australia lists 18 types of high risk construction work that need a SWMS and says a person conducting a business or undertaking (PCBU) must prepare, keep, comply with and review the SWMS, and give a copy to the principal contractor. WorkSafe WA says the WHS (General) Regulations 2022 and the WHS (Mines) Regulations 2022 require a SWMS before high risk construction work starts, and that none is needed for work of a minor nature (WorkSafe WA SWMS page).

WorkSafe Victoria’s list of high risk construction work, under its own regulations, includes work where a person could fall more than 2 metres, trenches or shafts deeper than 1.5 metres, demolition, confined spaces, work on or near energised electrical installations, work involving explosives and work in a tunnel. Check the list that applies in your state.

Safe Work Australia also publishes a Model Code of Practice for construction work. Its page says to check with your local regulator to find out whether the code has legal effect in your jurisdiction.

What is a JSA?

A JSA breaks a job into steps, lists the hazards at each step and records the controls. You may also see it called a JHA (job hazard analysis) or a JSEA. Different sites use different names and forms. The Safe Work Australia SWMS pages we read do not define a JSA. WorkSafe Victoria says JSAs and risk assessments are not required under legislation but are useful tools for identifying hazards and assessing risks, including for work that is not high risk construction work.

That means the form, the wording and when you fill one in come from your employer or site, not from a single legal template. A shorter pre-job check, often called a Take 5, is a related tool. Our Take 5 page explains how it differs from a JSA and a SWMS.

JSA vs SWMS comparison table

Point	SWMS	JSA (also JHA, JSEA)
Legal status	Required by the WHS regulations for high risk construction work (Safe Work Australia, WorkSafe WA). Victoria sets it in its own OHS Regulations 2017.	WorkSafe Victoria says JSAs are not required under legislation. A site or employer can still require one.
When it applies	Before high risk construction work starts. Safe Work Australia lists 18 types.	Any task your employer or site chooses, including work that is not high risk construction work.
Who prepares it	The duty holder doing the work. Safe Work Australia says a PCBU must prepare, keep, comply with and review it, and give a copy to the principal contractor.	Whoever the site or company procedure says.
What it contains	The high risk construction work, the hazards and risks, and the measures that control them (WorkSafe Victoria).	Usually the job steps, the hazards at each step and the controls, as in our JSA template.
Review	In Victoria, reviewed and revised if needed when the work changes or when risks are not adequately controlled, for example after an incident.	As set by the company procedure.
Copy on site	In Victoria, kept for the duration of the work and available where the work is done. Electronic copies are accepted.	As set by the company procedure.
If it is not followed	In Victoria, the work must stop immediately, or as soon as it is safe to do so, until it complies or the SWMS is revised.	As set by the company procedure.

Where the table says “as set by the company procedure”, there is no legal rule we have found, so follow your employer’s system.

How mine sites handle it

Mining is regulated state by state. In Western Australia, WorkSafe WA says the WHS (Mines) Regulations 2022 require a SWMS before high risk construction work starts. Its mining and exploration page also says mine operators must establish a mine safety management system, and that the system must identify hazards and assess, eliminate or control the risks.

So on a WA mine site, high risk construction work needs a SWMS. The WorkSafe WA pages we read do not say which task-level form to use for other work, so that is a decision for the operator’s own safety management system. It can be a JSA, a Take 5 or a permit, depending on the site. Read your induction pack, and ask your supervisor which form applies to the job you are about to do. Our guide to SWMS and JSA for mining work goes into more detail, and our permit to work guide covers the permit side.

Which do you need?

Construction work on the list (for example a person at risk of falling more than 2 metres, confined space work, demolition or work near energised electrical services): you need a SWMS before you start.
A routine task that is not on the list: a SWMS is not required, but the site or your employer may still require a JSA or a Take 5.
Work of a minor nature: WorkSafe WA says a SWMS is not required, though other safety controls and site procedures still apply.
Not sure: ask the person in charge of the work, the principal contractor or your state regulator before starting. When a task could be high risk construction work, treat it as needing a SWMS until someone responsible confirms otherwise.

Having a SWMS does not remove the need for your site’s other checks, which can include a JSA, a Take 5 or a permit. For tickets that are often linked to these tasks, see working at heights, confined space and the white card.

Free SWMS and JSA templates

Use a template as a starting point and write in the real job, hazards and controls. A SWMS has to cover the actual work. WorkSafe Victoria says the people most familiar with the work, including affected employees and their health and safety representatives, should be involved in developing it.

Frequently asked questions

Is a JSA the same as a SWMS?

No. A SWMS is a specific document that is legally required before high risk construction work starts. A JSA (job safety analysis, also called a JHA or JSEA) is a general risk assessment tool. WorkSafe Victoria says a SWMS is not the same as a risk assessment or JSA.

Is a JSA a legal requirement?

WorkSafe Victoria says JSAs are not required under legislation but can be useful for identifying hazards and assessing risks, including for work that is not high risk construction work. Your employer, client or site can still require one under its own procedures, so follow your induction and ask your supervisor.

When do I need a SWMS?

Before you start high risk construction work. Safe Work Australia lists 18 types of high risk construction work, and WorkSafe WA says the WHS (General) Regulations 2022 and the WHS (Mines) Regulations 2022 require a SWMS before that work starts. WorkSafe WA also says a SWMS is not required for work of a minor nature. Rules differ by state, so check your regulator.

Do mine sites use a SWMS or a JSA?

In Western Australia, the Mines Regulations require a SWMS for high risk construction work, and mine operators must also have a mine safety management system that identifies hazards and assesses, eliminates or controls risks. Which task-level form a site uses for other work is a decision for the operator, so check your induction pack and ask your supervisor.

Can I use a free SWMS template?

A template is a starting point. A SWMS has to describe the actual work, hazards and controls on your job, and WorkSafe Victoria says the people most familiar with the work, including affected employees and health and safety representatives, should help develop it. Our SWMS and JSA template pages are linked below, as is Safe Work Australia's interactive SWMS tool.

What happens if a SWMS is not followed?

In Victoria, the regulator says high risk construction work must stop immediately, or as soon as it is safe to do so, and cannot resume until it complies with the SWMS or the SWMS is reviewed and revised if necessary. Other states have their own regulations, so check yours.

Safe Work Australia publishes the model WHS laws, and each state and territory decides what applies in its jurisdiction. Safe Work Australia says to check with your local regulator whether its Code of Practice has legal effect where you work. The Victorian points above come from WorkSafe Victoria and relate to Victoria’s OHS Regulations 2017, which are not the model WHS laws. The Western Australian mining points come from WorkSafe WA only. We have not read state mining regulator guidance for other states, so we do not state their rules here. Confirm what applies on your site with your supervisor, your induction pack or your state regulator.
