Airbnb and Holiday Accommodation on Tank or Bore Water — Your Testing Obligations
If you're running a short-term rental, farm stay, eco lodge, or any form of holiday accommodation on a private water supply — tank water, bore water, or rainwater — you have obligations that most accommodation hosts on private supplies aren't aware of.
A guest who gets sick from contaminated water at your property is not just a bad review. It is a public health incident with potential liability consequences under state public health and food safety legislation. The fact that your water looks and tastes clean provides no protection — the contaminants most relevant to private water supply safety are consistently invisible, odourless, and tasteless at concentrations that can still affect health.
This article covers the regulatory landscape, what a compliant test looks like, and how to get it done before your next guest checks in.
For a broader overview of what constitutes a private water supply and who the term applies to under Australian law, see our guide to what is a private water supply.
The regulatory landscape — what the law actually says
Private water supply regulation in Australia is a state matter and the frameworks vary significantly. What is consistent across all states is that commercial operators providing accommodation to paying guests cannot simply assume their water supply is safe — and the liability exposure from a guest illness is real regardless of how actively your local council is enforcing the rules.
New South Wales — the clearest obligation
NSW has the most clearly defined framework for private water supply operators. The Public Health Act 2010 and Public Health Regulation 2022 explicitly classify tourist accommodation not connected to town water as a private water supplier. These operators are required to develop and adhere to a Quality Assurance Program (QAP) for their water supply — a documented risk management plan covering the water source, potential contamination risks, monitoring, and corrective actions.
Local councils are the primary enforcement body, with NSW Health providing oversight and guidance. The NSW Private Water Supply Guidelines set out what a QAP must contain. Inspections by council environmental health officers are a real possibility, particularly following a complaint or reported illness.
NSW Health recommends regular testing as part of any QAP, with results benchmarked against the Australian Drinking Water Guidelines. NATA-accredited laboratory analysis is specified as the required standard.
Queensland — guidelines without a specific framework
Queensland Health is explicit that there is no specific regulatory framework governing private drinking water supplies in Queensland. However, the Public Health Act 2005 gives local governments the power to issue public health orders to manage risks associated with private water supplies, and some councils impose licence conditions on accommodation premises under the Food Act 2006 or local laws.
Queensland Health has published detailed guidelines for managing private drinking water supplies in commercial and community premises. While these are guidance rather than law, they represent the standard against which any incident would be assessed. Accommodation operators relying on private water in Queensland operate without a clear regulatory mandate but with clear liability exposure if something goes wrong.
South Australia — formal exemptions but liability remains
SA Health's Safe Drinking Water Act 2011 exempts domestic rainwater tanks and private bore water supplies from formal registration requirements. Short-term accommodation facilities on rainwater tank supplies are also specifically listed as exempt from the formal requirements of the Act.
This exemption does not eliminate liability. SA Health still publishes specific guidance for accommodation premises on private water supplies and recommends that operators ensure their water is safe. An accommodation operator in SA whose guest contracts a waterborne illness from tank water is not protected from civil liability by the fact that they are exempt from the formal registration requirement.
Western Australia — general duty of care
The Public Health Act 2016 establishes a general public health duty in WA, supported by remaining provisions of the Health (Miscellaneous Provisions) Act 1911 during the ongoing legislative transition. There is no specific private water supply registration framework equivalent to NSW, but the general duty to not cause public health harm applies to accommodation operators. The WA Department of Health recommends regular testing of private water supplies used in accommodation.
Victoria — local government and food safety
Victoria's Public Health and Wellbeing Act 2008 provides the framework for public health risk management. Accommodation operators on private water supplies are also subject to food safety legislation if they provide food or beverages to guests. Local councils are the relevant enforcement authority.
The liability angle applies everywhere
Regardless of which state your property is in and how active local enforcement is, the liability exposure from a guest waterborne illness is consistent. Australian consumer law requires that services — including accommodation — be provided with due care and skill. Accommodation that results in a guest illness from contaminated water is a service failure with potential consequences under consumer law, negligence principles, and your short-term rental insurance policy.
Many short-term rental insurance policies include conditions around water supply safety. A claim arising from a waterborne illness at a property that has never been tested may face scrutiny.
What Airbnb's own policies say
Airbnb's host standards require that listings provide access to clean, safe drinking water. Where the property is on a private water supply, hosts are responsible for ensuring that supply is safe. Airbnb does not prescribe specific testing requirements, but in the event of a guest illness, a host who cannot demonstrate they took reasonable steps to verify water safety is in a difficult position — both with Airbnb and potentially with a council environmental health officer.
A current NATA-accredited water quality test result is the most defensible documentation of reasonable diligence available.
The specific risks for accommodation providers
The risk profile for accommodation properties on private water supplies is higher than for private households for three reasons:
Guest vulnerability — Your guests include pregnant women, elderly visitors, immunocompromised individuals, infants, and international travellers. These groups are significantly more vulnerable to waterborne illness than a healthy adult who has been drinking the same water supply for years and has some degree of acquired tolerance.
Turnover and unfamiliarity — Unlike a household where residents notice gradual changes in taste or odour, guests have no baseline. They cannot identify that the water tastes different from last month. A property owner who visits infrequently is also poorly placed to notice slow changes in water quality.
Volume of use — Short-term accommodation guests typically use more water per person per day than permanent residents — showers, cooking, drinking, ice. Higher consumption means higher exposure.
What a compliant test looks like
A test result that demonstrates reasonable diligence for accommodation purposes should include at minimum:
Microbiology — E. coli and Thermotolerant Coliforms are non-negotiable. A positive E. coli result in a water supply used for guest drinking and food preparation is a serious public health event. Microbiology must be conducted by a NATA-accredited laboratory using a cold-chain sample — kept chilled from collection through to lab receipt.
Metals and chemistry — For tank water, a metals panel covering lead, arsenic, zinc, copper, and manganese alongside full water chemistry. For bore water, the same metals panel with the addition of uranium and iron.
Nutrients — Nitrate is particularly relevant where guests include infants or young children. The ADWG health guideline for nitrate is 50 mg/L — at elevated concentrations it poses a serious risk to infants under three months.
The result should come from a NATA-accredited laboratory under ISO/IEC 17025, include a formal certificate of analysis, and compare results against the Australian Drinking Water Guidelines. Keep the result on file and make it available to your local council environmental health officer if requested.
How often to test
Annual testing is the appropriate baseline for accommodation properties on private water supplies. Also test:
When first listing a property on a private water supply
After any roof, gutter, tank, or bore maintenance
After extended dry periods followed by heavy rainfall
After changes in taste, colour, or odour
After a nearby bushfire or significant smoke event
When the property has been unoccupied for an extended period
For properties with high guest turnover, consider testing every six months. The cost of a test is a fraction of your liability exposure.
Which kit is right for your property
Tank water accommodation properties:
The Tank Water Essentials kit covers microbiology, metals including lead, arsenic, and zinc, full water chemistry, nutrients including nitrate, turbidity, colour, and fluoride — approximately 38 parameters benchmarked against the ADWG. The right starting point for most accommodation properties on tank water.
If your property is near a defence base, airport, or fire training facility, Tank Advanced adds 30 PFAS compounds at trace detection level.
For a full breakdown of what tank water typically contains and the risk categories relevant to accommodation properties, see our complete guide to rainwater tank water quality in Australia and our guide on how often tank water should be tested.
Bore water accommodation properties:
The Bore Water Essentials kit covers microbiology, 22 metals including arsenic, uranium, iron, and manganese, full water chemistry, nutrients, turbidity, colour, and fluoride — approximately 42 parameters benchmarked against the ADWG. Microbiology inclusion is essential for any bore supply used for guest drinking — bore water has no disinfection and no regulatory monitoring.
If your property is near a defence facility, airport, or industrial site, Bore Advanced adds 30 PFAS compounds at trace detection level.
Documenting your due diligence
Keep the following on file for each property on a private water supply:
Most recent NATA-accredited test result and certificate of analysis
Date of test and laboratory that conducted it
Any treatment systems installed (UV, filtration) and their last service date
Any maintenance carried out on tank, bore, gutters, or roof since the last test
If a council environmental health officer visits or a guest raises a concern, this file demonstrates you have taken reasonable and documented steps to ensure water safety.
Safe Water Lab provides mail-order tank and bore water testing for accommodation providers across Australia using NATA-accredited laboratory analysis. All results are benchmarked against the Australian Drinking Water Guidelines with plain-language explanations of any exceedances. Results include the original NATA certificate of analysis.
