South Australia Just Dropped the Fall Threshold to 2 Metres. The Data Says That’s Where People Were Falling.

On 1 July 2026, South Australia reduced the working-at-height threshold for high-risk construction work from three metres to two. Any work with a risk of a fall of more than two metres is now high-risk construction work, and a Safe Work Method Statement is legally required before the work starts, whether you are a sole trader, a labourer, an apprentice or a contractor.

That is the whole change, and it sounds small. One metre. But the number that should stop you is not the metre. It is this one:

Read that again. For years, the height range where most people were actually falling sat underneath the threshold that triggered the requirement to plan the work properly. The rule was drawing a line above the danger.

What changed on 1 July

• The Work Health and Safety Regulations 2012 (SA) now define high-risk construction work as work involving a risk of a fall of more than two metres, down from three.
• Construction businesses must prepare and adhere to a SWMS for that work, developed in consultation with workers, and readily available on site before the work begins.
• This brings SA into line with the national model WHS regulations. Every other Australian jurisdiction already used two metres. South Australia was the outlier.

The cost of the old position, on ReturnToWorkSA’s numbers: since 2016/17, falls from height in construction have produced roughly 1,585 workers compensation claims at a total claims cost of more than $64 million. That is only the insured cost. It is not the cost of the person.

The sentence in the regulator’s release I would frame

SafeWork SA says the change means employers “can no longer erroneously rely on the higher height threshold to avoid providing adequate fall protection, particularly in the residential sector.”

Erroneously rely on. That is a regulator stating, on the record, that businesses were using the three-metre line as a reason not to control a risk they knew was there. And they were. I have watched it happen. “It’s only a metre and a half, mate.” Two and a half metres onto concrete will kill you just as reliably as four will. Gravity has never once consulted the regulations.

Here is the part almost everyone gets wrong

The threshold has never been the duty.

Nothing about the old three-metre rule ever made it lawful to let someone fall 2.4 metres. Your primary duty under the WHS Act, to eliminate the risk or minimise it so far as is reasonably practicable, applied at every height, including one metre, and it always did. The three-metre line only ever governed one specific administrative trigger: whether a SWMS was mandatory.

So if the honest internal reaction in your business to 1 July was “we now have to protect people between two and three metres”, that is not a compliance update you just received. That is a confession. You were already required to. What you now also have to do is write it down.

I say that not to score a point but because it changes what you should actually fix. If you had genuine fall controls in place at 2.2 metres and simply never documented them, this is a paperwork exercise. If you did not, no SWMS will save you. The document is not the control. It is the record of the thinking that produced the control. A SWMS written to satisfy an inspector, describing a control nobody uses, is worse than nothing: it is signed, dated evidence that you understood the hazard and did not manage it.

What to do this month

1. Find the work between two and three metres. It is the roof edge on a single-storey, the top plate, the ladder work at gutter height, the scaffold you did not think warranted an edge rail. In residential construction it is nearly everything. That is exactly where the SA data says the injuries are.
2. Re-check whether your SWMS templates were height-gated. Many were written to fire at three metres. If yours triggers on the old number, it is now silently non-compliant on the most common job you do.
3. Work the hierarchy honestly, and record why. Can the work be done from the ground? Can you use a passive fall-prevention device, a guardrail or a platform, before you reach for a harness? Most fall SWMS I read leap straight to PPE and cannot explain why. That gap is the finding.
4. Consult the workers doing the job. Not optional. The regulation requires the SWMS to be developed in consultation, and in any case, the apprentice on the ladder knows where the wobble is.
5. Put the SWMS on site, not in the office. “Readily available at the workplace” is the wording. A document in a server folder in Adelaide is not available on a roof in Elizabeth.

If you work across state lines

This one is easy, and it is the rare case where harmonisation genuinely helps you: two metres is now the number everywhere. If you have been running one SWMS trigger in SA and another in Victoria or New South Wales, collapse them into a single national standard and stop maintaining the divergence. Two thresholds in one business is a system that will eventually apply the wrong one on the wrong site.

And note that falls are not just an SA preoccupation. SafeWork NSW has named falls from heights as one of its four regulatory priorities for 2026-27, on the back of 600-plus incidents and five deaths. Two regulators, one hazard, same year. If you need a signal about where inspectors will be standing, that is it.

Where a management system earns its keep

A regulatory threshold moved by one metre and, for a lot of businesses, every SWMS template, induction pack, toolbox talk and subcontractor pack in the business is now out of date. Nobody will notice until an inspector does.

That is the unglamorous, real argument for ISO 45001. Not the certificate on the wall. Clause 6.1.3 requires you to determine and have access to your legal requirements and to keep that information current; clauses 8 and 9 require that changes flow through to controls and get checked. A system that works catches a change like this and pushes it into every affected document. A system that does not is just a folder, and a folder does not know the number changed.

You do not need certification to take fall protection seriously. But you do need some mechanism that notices when the law moves under you, because this will not be the last time it does.
