BOM Issues Severe Weather Alerts: What Employers Must Do Under Australian Law

When the Bureau of Meteorology (BOM) issues a severe weather warning, most Australians check the sky and reach for an umbrella. For employers with outdoor workforces, however, a BOM alert is far more than a forecast — it is a legal trigger that activates specific obligations under Australian work health and safety law.

In May 2026, BOM has issued severe weather warnings across multiple states: damaging winds gusting to 90 km/h in Victoria on 7 May, severe thunderstorm warnings across South Australia on 16–18 May, and flash flooding risks across Queensland earlier in the season. Each of these events placed thousands of outdoor workers — construction crews, agricultural workers, delivery drivers — in environments their employers are legally required to make safe.

What BOM's Warnings Mean in Legal Terms

Australia's Model Work Health and Safety (WHS) Act requires every employer — legally termed a "person conducting a business or undertaking" or PCBU — to ensure the health and safety of workers "so far as is reasonably practicable." This duty does not pause because conditions are difficult; in severe weather, it intensifies.

The Fair Work Ombudsman explicitly references the Bureau of Meteorology in its official guidance, recommending that employers monitor BOM alerts as part of their risk management process. This makes a BOM warning not merely meteorological information — it is data your business is expected to act on.

Failure to act can be costly. Breaches of WHS obligations can attract penalties of up to $3 million for corporations under jurisdictions that have adopted the Model WHS Act. Serious offences involving reckless disregard for worker safety can result in criminal prosecution.

The Three Steps Every Employer Must Take

Safe Work Australia's guidance on working in hazardous weather identifies a clear process for employers when severe conditions are forecast or active. According to Safe Work Australia's official guidance on hazardous weather, employers must:

Step 1: Assess the risk. Review the nature of the warning against the actual tasks your workers perform. A roof tiler and a warehouse worker face entirely different risks from the same BOM wind alert. Risk assessments must be documented.

Step 2: Implement controls. The hierarchy of WHS controls means that telling workers to "be careful" does not satisfy your legal duty. Practical options include rescheduling outdoor work to safer times of day, providing shelter and mandatory rest areas, rotating tasks to reduce individual exposure, and suspending high-risk activities entirely until conditions clear.

Step 3: Consult with workers. Workers must be consulted on health and safety matters that affect them directly. Health and Safety Representatives (HSRs) have formal powers under WHS legislation to issue Provisional Improvement Notices if they believe safety standards are being ignored.

What Happens to Pay During Severe Weather?

The question of pay during weather-related work stoppages regularly produces disputes between employers and employees. Under the Fair Work Act 2009, employers may stand workers down without pay when work cannot usefully be performed due to a cause for which the employer cannot reasonably be held responsible — which includes severe weather events and natural disasters.

However, a stand-down is explicitly a measure of last resort. Before implementing one, the Fair Work Ombudsman advises employers to genuinely explore alternatives, including:

• Working from home or relocating to an unaffected site
• Redeployment to indoor or lower-risk tasks
• Flexible scheduling to avoid the most dangerous weather window
• Offering access to paid or unpaid leave

Implementing a stand-down without exhausting these alternatives may constitute an unlawful stand-down under the Fair Work Act, exposing employers to back-pay orders and financial penalties.

Inclement Weather Clauses: Check Your Award First

Many modern awards and enterprise agreements — particularly in construction, agriculture, landscaping, and outdoor services — contain specific "inclement weather" provisions that go beyond the bare minimum of the Fair Work Act. These clauses typically define:

• What constitutes inclement weather, sometimes with reference to BOM warnings, temperature thresholds, or rainfall intensity
• How long workers are entitled to shelter on site and receive pay while waiting for conditions to improve (often two to four hours)
• What pay entitlements apply during weather-related stoppages

A common mistake is for employers to send outdoor workers home immediately when rain begins, without checking whether their applicable award requires a waiting period on full pay. Getting this wrong means underpaying your workforce — a risk that multiplies quickly across a large team.

Force Majeure and Commercial Contracts

Severe weather doesn't only affect worker safety — it can disrupt commercial contracts, supply chains, and project timelines. When a BOM-declared event prevents your business from meeting contractual obligations, a force majeure clause may excuse non-performance. Whether it applies depends entirely on the specific wording of your contract.

Broadly drafted clauses covering "severe weather events" or "acts of God" may provide protection. Narrower clauses requiring a declared state of emergency or a specific category of natural disaster may not. Meanwhile, if a third party's failure to act on a BOM warning causes your business loss — a contractor who did not secure equipment, a supplier who failed to warn of incoming delays — you may have grounds for a negligence or breach of contract claim.

Act Before the Next Warning Arrives

BOM currently maintains active warnings across multiple Australian states, and the southern hemisphere's winter storm season is now underway. For businesses with outdoor workforces, the window to prepare is now — not mid-storm.

Key steps to take this week:

1. Subscribe to BOM alerts for your region via the BOM website or app
2. Review your applicable modern award or enterprise agreement for inclement weather provisions
3. Update your WHS risk management plan to include severe weather scenarios and sign-off procedures
4. Brief supervisors and HSRs on stand-down alternatives and consulting obligations
5. Review commercial contracts for force majeure language and consider updating to reflect BOM warnings explicitly
