Safe Work Method Statements for High-Risk Construction Work in South Australia

What it is

South Australia requires a Safe Work Method Statement (SWMS) to be prepared before any high-risk construction work commences under regulation 299 of the Work Health and Safety Regulations 2012 (SA). Regulation 291 defines the categories of high-risk construction work.

SafeWork SA enforces the framework. The 1 July 2026 amendment reducing the fall threshold from 3 metres to 2 metres broadened the SWMS scope for residential construction work.

Categories align with model WHS

SA's regulation 291 lists the 18 categories aligned with the model WHS Regulation (NSW, QLD, WA, TAS, ACT, NT).

The 1 July 2026 fall threshold reduction

Before 1 July 2026, SA reg 291 required a SWMS for work involving a risk of a person falling more than 3 metres. From 1 July 2026 the threshold reduced to 2 metres, bringing SA into line with the model WHS Regulation.

That change significantly expands the SWMS scope for residential construction. Most single-storey residential work at eaves or roof level now triggers SWMS obligations that did not apply under the previous 3-metre threshold.

TradeForm SA templates were updated on 1 July 2026 to reflect the 2-metre fall threshold across all fall-risk SWMS templates.

When a SWMS is required

Regulation 299 requires the SWMS to be prepared BEFORE the high-risk construction work commences.

What the SWMS must contain

Regulation 299 requires identification of the type of work, hazards, control measures and implementation approach.

Review and principal contractor duties

Regulation 300 requires SWMS review when the work method changes, if a control measure is inadequate, or after a notifiable incident. Regulation 309 requires the principal contractor to obtain SWMS from each contractor.

Penalties

Regulation 299 offence carries penalties in line with the model WHS Regulation.

Interaction with 1 July 2024 industrial manslaughter

SWMS failures that cause a workplace death can be prosecuted under section 30A industrial manslaughter (from 1 July 2024). SA prosecutors treat inadequate SWMS as evidence of the required conduct-plus-causation elements.

Interaction with CBS licensing

WHS Act SWMS breaches by a SA building work contractor licensee can trigger CBS disciplinary action alongside SafeWork SA enforcement.

How South Australia compares

SA's SWMS framework aligns with NSW, QLD, WA, TAS, ACT and NT under the model WHS Regulation from 1 July 2026 (when the 2-metre fall threshold aligned SA with the other jurisdictions). Before that date, SA's 3-metre threshold was a state-specific variation.

The 1 July 2026 change is one of the most significant SA WHS reforms in recent years. Combined with the 1 July 2024 industrial manslaughter commencement, SA has significantly strengthened its construction industry safety framework across 24 months.
