Australia’s AS 4687:2022 standard represents the biggest overhaul of temporary fencing regulations in over 15 years, introducing a four-part framework that addresses real gaps in how fences perform under harsh Australian conditions. The most significant change requires dual-sided wind load testing, while new documentation demands include site-specific wind calculations and certified test reports. Construction managers and site engineers must now classify their terrain and importance levels correctly to meet these stricter AS 4687 compliance requirements, which can prevent costly project shutdowns and hefty regulatory fines.
Why the 2022 Standard Changes Everything
The 2022 revision completely rewrites how Australia handles temporary fencing safety, moving from basic guidelines to a comprehensive engineering system that addresses real-world performance gaps.
This isn’t just another regulatory update. The new Australian temporary fence standards create a complete safety framework that engineers and site managers can actually use to prevent failures. The changes directly tackle problems that have plagued the industry for years, from coastal wind damage to overcrowded urban construction sites where temporary fencing compliance implementation becomes critical.
Breaking Down the Four-Part System
Instead of forcing everyone to use the same rules, the new standard splits requirements into four targeted parts that make finding the right regulations much easier.
You won’t waste time digging through swimming pool rules when you’re installing construction site barriers. This organized approach streamlines temporary fencing compliance implementation across different project types.
The Four Essential Parts Explained
Here’s how the new structure works:
- Part 1: General Requirements – Base rules that apply to every temporary barrier project
- Part 2: Temporary Fencing and Pedestrian Barriers – Construction and event fencing specifics
- Part 3: Temporary Hoardings – Detailed requirements for solid barrier installations
- Part 4: Temporary Swimming Pool Fencing – Pool construction and maintenance rules
Key Terms That Actually Matter
The updated standard eliminates confusion with precise definitions that directly impact your compliance strategy:
- Stability Class vs. Importance Levels: Stability Class handles basic 54 km/h wind resistance, while Importance Level 2 demands engineered solutions for 108+ km/h winds on high-risk sites
- Terrain Category Classifications: TC1 covers open flat areas, TC4 handles dense city centers, and each category changes your wind load calculations significantly
- Shielding Multipliers: These numbers (HS = 0.8, MS = 0.9, NS = 1.极) reduce wind loads based on surrounding buildings and trees
Wind Load Engineering That Actually Works
Getting wind load calculations right isn’t optional anymore – it’s a mandatory design requirement that separates compliant installations from dangerous failures.
Most guides mention wind resistance but skip the complex math that keeps people safe. The new dual-sided anti-overturning testing requirements make these calculations even more critical for AS 4687 compliance.
Site-Specific Wind极e Calculations
The standard provides this formula for determining design wind speeds at your exact location:
Vdes = VR × Md × (Ms × Mt × Mz)
Each variable represents:
- VR = Regional gust wind speed (37 m/s for Importance Level 1 sites)
- Md = Wind direction multiplier (typically 1.0)
- Ms = Shielding multiplier (ranges from 0.8-1.0 based on surrounding obstructions)
- Mt = Topographic multiplier (1.0-1.7 depending on slope conditions)</极>
- Mz = Terrain/height multiplier (0.70-1.03 range)
Real-World Application Examples
The difference between locations is dramatic. A temporary fence in Darwin’s open terrain needs nearly 50% more bracing than an identical installation in Melbourne’s CBD, even with similar weather forecasts. The Australian temporary fence standards account for these regional variations through precise calculations.

Product Specifications That Keep Projects Moving
Not every fencing product meets the new testing and material requirements – choosing compliant products prevents costly delays and safety incidents.
Cheap imitations often fail the new dual-sided anti-overturning testing protocols, leaving you scrambling for replacements mid-project.
Material Standards You Can’t Ignore
The standard mandates specific properties that separate quality products from dangerous knockoffs:
- Galvanization Requirements: Minimum 42μm zinc coating protects against Australian weather conditions
- Mesh Specifications: Maximum 75mm spacing prevents climbing access while maintaining visibility
- Frame Construction: 32mm OD tubing with 2.0mm minimum wall thickness for heavy-duty applications
New Testing Requirements and Documentation
The 2022 update introduces a game-changing testing rule: dual-sided anti-overturning testing. Temporary fencing must now withstand wind forces from both directions, not just the braced side. Products also undergo combination loading tests that simulate simultaneous wind, impact, and crowd pressure. You must obtain and maintain certification documentation proving each product passed these comprehensive tests.
Site Implementation Strategies That Work
Your AS 4687 compliance strategy starts with correctly classifying your site’s risk level and environmental conditions – get this wrong and your entire installation could fail when you need it most.
Misclassification leads to under-engineered installations that create liability issues and project shutdowns.
Choosing Between Stability Class and Importance Level Applications
This decision shapes your entire compliance approach:
- Stability Class (54 km/h): Works for low-risk sites with minimal foot traffic and short timelines under 30 days
- Importance Level 2 (108+ km/h): Required near schools, parks, or high-traffic areas where fence failure could cause injuries or significant economic impact
Hoarding Systems and Special Requirements
Solid hoarding barriers face unique wind challenges that require specialized ballast and bracing calculations beyond standard temporary fencing requirements.
Hoardings catch wind like giant sails, making the Australian temporary fence standards especially strict for these installations. This makes the temporary fencing legal requirements for hoarding particularly rigorous.
Counterweight vs. Fixed Foundation Approaches
The standard treats these systems very differently:
- Counterweight Design: Demands precise ballast calculations based on height and wind exposure, with secured ballast that can’t be removed or displaced
- Bracing Requirements: Additional bracing at gates and open ends follows a 2x height requirement
- Inspection Schedules: All temporary hoarding systems need reinspection and recertification every six months
Pool Fencing Gets Official Recognition
For the first time, temporary pool fencing receives official recognition in Australian standards, giving builders and installers a clear compliance path that building surveyors must accept.
This change eliminates the gray area that previously caused rejections and delays. The standard integrates with AS 1926.1:2024 swimming pool safety requirements and specifies critical details like exclusion zones around climbable objects and self-closing gate mechanisms with strict performance criteria.

Your compliance packet must include:
- Site-specific wind condition design calculations
- Detailed temporary fence installation and maintenance methodology statements
- Regular inspection and maintenance records
- Product test certificates from accredited laboratories
- Formal certificate of AS 4687 compliance
Critical Implementation Questions Answered
How does AS 4687:2022 affect existing temporary fencing inventory?
Existing stock may require re-certification against the 2022 standard, particularly for the new dual-sided anti-overturning testing requirements. While transition arrangements exist, all new projects should use products that meet current Australian temporary fence standards.
What documentation is mandatory for compliance demonstration?
You need design calculations, product test certificates, temporary fence installation and maintenance method statements, and ongoing inspection records at minimum. The exact documentation requirements depend on your site’s importance level and fencing type.
How frequently must temporary hoardings be reinspected?
The standard requires reinspection and recertification for all temporary hoarding installations every six months. You must conduct additional inspections after severe weather events like storms or cyclones.
What are the consequences of non-compliance with the updated standard?
Non-compliance risks include immediate project shutdown, regulatory fines exceeding $250,000, voided insurance coverage, and personal liability for incidents caused by non-compliant installations. These consequences make proper AS 4687 compliance essential for protecting both projects and careers.
