# What you need to know about the AS1851 NSW Legislation Changes in 2026

29 September 2025

![What you need to know about the AS1851 NSW Legislation Changes in 2026](https://assets.precisecdn.com/cdn-cgi/image/width=950,height=620,fit=cover,quality=80,format=auto/2025_03_Precise_Air_201_Elizabeth_Sydney_Plantroom_Three_071_LREZ.jpg)

In February 2026 the Australian Standard 1851: Routine Service of Fire Protection Systems and Equipment standard will be legislated in NSW. This change brings NSW in line with Queensland, Victoria, Tasmania and South Australia.

This update will have significant impacts on HVAC systems that are integrated with fire safety measures. We have developed an Advice that outlines implications for operating and servicing buildings, including the new requirements for fans operating in fire mode. Please see the Advice provided as an attachment.

At Precise Air, we are committed to supporting your compliance journey. Please contact us to coordinate fire mode testing, optimise scheduling, and minimise disruptions to your operations.
