If you own or manage a commercial building in Australia, you have almost certainly come across the term AS 1851. It appears in maintenance contracts, fire safety audit reports, AFSS lodgement documents, and council notices. But for many building owners, what it actually requires remains unclear.
AS 1851-2012 is the Australian Standard for the routine servicing of fire protection systems and equipment. It does not tell you how to design a sprinkler system or where to install a hydrant. It tells you how often to inspect what is already in your building, what to test and record at each visit, and how to compare current readings against the data captured when the system was first commissioned.
From 13 February 2026, compliance with AS 1851-2012 is mandatory in NSW for all Class 1b and Class 2 to Class 9 buildings. What was previously considered industry best practice is now the legal minimum.

AS 1851-2012 covers the routine servicing of all active fire protection systems and equipment installed in a building. The standard applies to a wide range of systems, including:
Note that some essential fire safety measures, including emergency lighting and exit signs, are maintained in accordance with AS 2293 rather than AS 1851, as referenced in the building’s fire safety schedule. Read our guide: Emergency Lighting Testing Requirements in Australia
For each system it covers, AS 1851 specifies exactly what must be inspected and tested at each service interval, what pass and fail criteria apply, what must be recorded, and how the current condition of the system must be compared against its commissioned baseline.
It is worth being clear about what AS 1851 does not do. The standard covers routine service only, meaning the planned preventive activity that keeps a system in its as-commissioned condition. It does not cover:
When a defect is identified during routine service under AS 1851, the required corrective work is separate from the routine service itself and must be documented and tracked independently.
One of the most important things building owners need to understand about AS 1851 is that it requires much more than a single annual inspection. The standard specifies servicing at multiple intervals, and every interval must be completed and documented for your maintenance program to be compliant.
The key service frequencies under AS 1851 include:
Monthly Basic operational checks on certain systems and components, particularly fire pumps, fire alarm systems, and sprinkler system control valves. Monthly checks are typically a visual inspection and functional confirmation rather than a full test, but they must be documented.
Six-Monthly More thorough testing across a range of systems, including fire hose reels, extinguishers, portions of the fire alarm system, and hydrant flow testing. Six-monthly intervals are where many buildings first discover they have been running a non-compliant program.
Annual A comprehensive inspection of every covered system, incorporating all monthly and six-monthly checks plus additional tests and measurements. The annual service is typically the most time-intensive visit and forms the foundation of the AFSS assessment.
Five-Yearly More intensive testing of specific components, including hydrostatic testing of extinguisher cylinders and detailed assessment of sprinkler system components. Five-yearly intervals require careful forward planning.
Beyond Five Years Certain components require testing at longer intervals, including sprinkler head sampling at 25 years and selected assessments of fire pump components.
AS 1851 requires some routine service inspections more frequently than once per year, and provides detailed guidelines for services every 5, 10, and 25 years. A compliant maintenance program must map every system in your building to every applicable service frequency, with no gaps.
Record keeping is as important as the inspections themselves under AS 1851. The standard requires:
A building owner who cannot produce current, complete maintenance records is in the same position as one whose systems have not been maintained at all, from a compliance and liability perspective.
All Fire Safe ANZ clients have 24/7 access to their complete maintenance records through our client portal, with hard copy logbooks maintained on site after every service visit.
Your AS 1851 records need to be complete, current, and on site. Fire Safe ANZ manages the full documentation trail for every client building. Get in touch
The building owner holds primary responsibility for ensuring all essential fire safety measures are maintained in accordance with AS 1851. This responsibility cannot be transferred by engaging a contractor. If your contractor does not carry out the required inspections at the required intervals, the liability rests with you as the building owner, not with the contractor.
Building owners include strata committees, owners corporations, and developers prior to occupation certificate being issued.
In practical terms, this means building owners must:

AS 1851 and the Annual Fire Safety Statement are closely connected. The AFSS certifies that all essential fire safety measures have been maintained to the required standard, and from 13 February 2026 that standard is AS 1851-2012. A building without a compliant AS 1851 maintenance program cannot produce a valid AFSS.
When an accredited practitioner attends to assess and endorse your AFSS, they will now check that your maintenance records demonstrate compliance with AS 1851-2012’s prescribed service frequencies, not just that systems appear functional on the day of inspection. A gap in your records is as significant as a gap in your maintenance.

While the February 2026 mandate is specific to NSW, AS 1851 is effectively the standard applied across Australia. In Queensland, Victoria, Western Australia, and other states and territories, AS 1851 is referenced in state legislation, building codes, and insurance requirements, making it the benchmark for fire protection maintenance regardless of whether it has been separately legislated.

From 13 February 2026, failure to comply with AS 1851 in NSW can result in:
Beyond the regulatory consequences, non-compliant fire protection systems represent a genuine risk to building occupants.
