Water Usage Charges in Rental Properties: A State-by-State Guide for Australian Property Managers

Every water bill in Australia carries two types of charges, and getting the distinction right is the starting point for everything else in this topic.

Fixed charges — the base supply or service fee, sewerage charges, drainage levies, and waterways infrastructure charges — are the landlord's responsibility in every Australian state and territory. These are charges tied to having a connected water supply, not to how much water a tenant uses. They cannot be passed to a tenant regardless of what the tenancy agreement says. If a tenancy agreement attempts to make a tenant liable for fixed water service charges, that clause is unenforceable.

Usage charges — the cost of the volume of water actually consumed, measured in kilolitres — can be passed to tenants in most states, but only when specific conditions are all satisfied simultaneously. If any one condition is not met, the entire usage charge remains with the landlord, even if the agreement attempts to transfer it.

When a water bill arrives, separate these two components before deciding what you can claim. Many water authority invoices label them clearly: "service charge" (fixed) and "usage" (variable). The fixed section is yours to pay regardless of who is living in the property. Whether you can recover the variable section from the tenant depends on the state-by-state rules below.

This distinction is more than administrative. In a bond dispute or tenancy tribunal, a landlord who has incorrectly charged a tenant for fixed supply costs — or charged usage costs when the conditions were not met — will often face not just repayment of the overcharged amount, but adverse findings on their overall conduct of the tenancy.

Most Australian states share a common framework for water usage charging. Three conditions are consistent across the majority of jurisdictions:

1. Separate metering. The property must be individually metered, meaning the water meter measures only that tenancy's consumption and not that of any adjoining dwelling or common area. Properties on a shared meter — common in some older apartment buildings and certain strata schemes — cannot pass on usage charges to tenants. If in doubt, ask the water authority for a metering confirmation or check the account details: individual property meters will show only that property's address on the account.

2. Tenancy agreement clause. The tenancy agreement must include a provision stating the tenant is responsible for water usage charges. In Queensland and New South Wales, the standard-form general tenancy agreement includes an optional clause that can be selected at the start of the tenancy. In other states, this obligation generally needs to appear as a special condition. A handshake understanding or a landlord's expectation that "it's standard" is not sufficient — the clause must be in writing in the agreement.

3. Amount is capped at actual cost. In all states that permit passing on usage, the amount charged to the tenant cannot exceed what the water authority actually charged the landlord for that period. No administration fee, handling margin, or markup can be added to a water bill before it is passed to a tenant.

A fourth condition applies in New South Wales, Victoria, and Queensland but not in WA, SA, Tasmania, NT, or the ACT: the property must meet water efficiency standards set by the relevant state regulations. This is the most frequently overlooked requirement and the most common reason a water charge claim fails.

Under the Residential Tenancies Act 2010 (NSW), a landlord or property manager can pass on water usage charges only when all four of the following conditions are satisfied throughout the billing period:

1. Separately metered. The property has its own water meter, or water is delivered by vehicle (applicable in some rural areas not connected to a reticulated supply).

2. Tenancy agreement includes the obligation. The residential tenancy agreement states that the tenant must pay for water usage. The standard NCAT-approved tenancy agreement form includes clauses for this; always confirm the clause is selected before executing the agreement.

3. Water efficiency standards are met. The property must meet the water efficiency measures prescribed in the Residential Tenancies Regulation (NSW). The standards apply to internal cold water taps (excluding garden taps and outdoor irrigation), showerheads, and toilets. NSW Fair Trading publishes the current device specifications at fairtrading.nsw.gov.au. The standards must be in place for the entire billing period — if a non-compliant fitting is installed mid-tenancy, the right to charge is suspended until it is replaced with a compliant one.

4. Amount does not exceed actual cost. The charge must equal the actual usage amount from the water authority's invoice.

When billing, the tenant must receive a copy of the water authority's bill or a written statement clearly identifying the usage period, the volume consumed, and the amount payable. Importantly, the tenant must be given at least 21 days to pay from the date they receive this document. Issuing a water invoice with a shorter payment window than 21 days, or failing to provide a copy of the underlying bill, breaches the Act.

Where a tenancy spans a water authority billing period — for example, a tenant moves in partway through a quarterly billing cycle — the property manager needs to calculate the usage attributable to the tenant's period (typically on a pro-rata daily basis) rather than passing on the whole bill.

Victoria's framework under the Residential Tenancies Act 1997 mirrors the general model but is distinctive in two ways: the water efficiency conditions are defined in terms of fixture functionality as well as installed device ratings, and the tenant must reimburse within 28 days of receiving the invoice (not days from a billing date).

To charge for water usage in Victoria, all of the following must apply:

Separately metered. As in other states, the property must have an individual meter.

Rental agreement clause. The rental agreement must include the water usage obligation. Standard Victorian residential rental agreements include this as a selectable clause.

Water efficiency conditions met. Consumer Affairs Victoria specifies that the rental provider must ensure all showerheads in the property meet the relevant water efficiency rating, no internal taps are dripping, and all toilets function correctly without running continuously. The distinction from NSW is that the condition covers tap functionality — a dripping tap disqualifies water charging even if it is technically a rated low-flow fitting. The rental provider bears responsibility for maintaining these fittings in compliant condition throughout the tenancy. If a showerhead or tap deteriorates, the right to charge usage is suspended until it is repaired or replaced.

Fixed charges are excluded. The fixed supply charge, sewerage charge, and any waterways levies are borne by the rental provider.

For billing: issue the tenant an invoice that identifies the billing period, the volume of water used, and the amount payable. The tenant is required to reimburse within 28 days of receiving the invoice. Consumer Affairs Victoria at consumer.vic.gov.au publishes current guidance on water efficiency standards and billing obligations.

Queensland's water charging rules are set by the Residential Tenancies and Rooming Accommodation Act 2008 (RTRAA 2008). The framework follows the three-condition model — separate metering, tenancy agreement clause, and water efficiency — but Queensland adds a billing deadline that catches many property managers out.

Separately metered. The premises must be individually metered. In some Queensland rental markets, particularly older unit complexes, shared metering is common. If the property shares a meter, usage charges cannot be passed on.

Water efficient premises. Queensland requires that the premises be "water efficient" as defined in the RTRAA 2008. The definition covers internal cold water taps and showerheads that meet applicable water efficiency ratings, as well as other prescribed fixtures. The Residential Tenancies Authority (RTA) at rta.qld.gov.au publishes current guidance on what qualifies as water efficient under Queensland law. As with other states, the efficiency requirement must be maintained throughout the tenancy.

Tenancy agreement clause. Form 18b (the General Tenancy Agreement prescribed by the RTA) includes standard terms that address water charging for separately metered properties. The relevant clause should be confirmed as active in the executed agreement.

The four-week billing deadline. This is the most operationally significant Queensland-specific rule: usage charges must be claimed from the tenant within four weeks of the landlord or property manager receiving the water authority's invoice. If a quarterly water bill sits in a property management inbox for more than four weeks before being passed to the tenant, the right to charge for that bill is forfeited. For agencies managing large portfolios, this deadline requires active systems to track incoming water bills — not passive reminders.

The RTA at rta.qld.gov.au is the authoritative source for current form versions and water efficiency requirements under Queensland law.

Western Australia's approach under the Residential Tenancies Act 1987 (WA) is simpler than the eastern states in one important respect: there is no water efficiency prerequisite. As long as the property is separately metered and the tenancy agreement requires the tenant to pay for water usage, usage charges can be passed on.

What cannot be passed on in WA: the fixed water service charge, sewerage charges, and any drainage or infrastructure levies. Water Corporation bills typically show the water service charge and sewerage charge as fixed line items — these remain with the landlord. Only the usage component (measured in kilolitres) can be recovered from the tenant.

If in doubt about which component of a Water Corporation bill is recoverable, Consumer Protection WA at consumerprotection.wa.gov.au provides guidance on reading water bills in the context of rental properties.

For property managers operating across multiple states, the absence of an efficiency requirement in WA means a different compliance checklist applies than in NSW, VIC, or QLD. An inspection checklist that confirms showerhead ratings as a prerequisite to billing is a NSW/VIC/QLD requirement — not a WA one.

South Australia follows a straightforward framework under the Residential Tenancies Act 1995 (SA). Water usage charges can be passed to a tenant where the property is separately metered and the tenancy agreement states the tenant will pay for usage. There is no water efficiency prerequisite.

Fixed supply charges, sewerage charges, and infrastructure levies remain with the landlord.

The tenancy agreement must include the obligation clearly. SA's standard residential tenancy agreement forms, available through CBS (Consumer and Business Services SA at cbs.sa.gov.au), include appropriate clauses for water usage charging in separately metered properties.

One practical note for South Australian properties: some older Adelaide rental properties in areas serviced by SA Water are on shared meters for a block of dwellings. As in all other states, a shared meter disqualifies water usage charging for all affected dwellings until individual metering is installed.

These three jurisdictions apply the same core framework — separately metered, tenancy agreement clause required — without a water efficiency prerequisite, but the ACT has a significant structural difference worth understanding.

Australian Capital Territory. Under the Residential Tenancies Act 1997 (ACT), landlords bear primary responsibility for rates and charges on a rental property. Standard-form tenancy agreements in the ACT do not typically include water usage charging provisions by default. The ACT regime is more restricted than other jurisdictions in how tenancy agreement conditions can deviate from standard terms. Property managers intending to pass on water usage charges in the ACT should confirm with Access Canberra at accesscanberra.act.gov.au that the intended agreement clause is enforceable under the current standard-form agreement requirements before the tenancy commences.

Tasmania. The Residential Tenancy Act 1997 (Tasmania) permits water usage charging where the property is separately metered and the tenancy agreement specifies the tenant's obligation. Fixed supply charges and sewerage charges remain with the landlord. Consumer, Building and Occupational Services (CBOS) at cbos.tas.gov.au is the relevant authority.

Northern Territory. The Residential Tenancies Act 1999 (NT) permits water usage charging in separately metered properties where the tenancy agreement includes the obligation. Fixed charges are the landlord's responsibility. Consumer Affairs NT at nt.gov.au/law/consumer is the relevant authority.

Once you have confirmed that the conditions for your state are met, the billing process follows a consistent pattern regardless of jurisdiction:

Step 1: Receive and review the water authority's invoice. When it arrives, identify the usage component (kilolitres consumed × rate per kilolitre) separately from fixed charges. Do not delay — Queensland's four-week deadline starts from receipt.

Step 2: Calculate the tenant's share. If the billing period spans a change of tenancy — for example, a tenant moved in or out mid-period — apportion the usage on a pro-rata daily basis. Neither an incoming nor outgoing tenant is responsible for usage outside their occupancy period.

Step 3: Prepare and send the tenant's invoice. Issue a written document that clearly states the usage period, the volume consumed (in kilolitres), and the amount payable. Attach a copy of the water authority's invoice or include all the information from it. This is a legal requirement in NSW and best practice everywhere.

Step 4: Observe the payment window. NSW: tenant must have at least 21 days to pay from the date of receipt. Victoria: tenant must reimburse within 28 days of receiving the invoice. Queensland: usage must be billed within four weeks of the landlord receiving the supplier invoice. Other states: follow the payment terms in the tenancy agreement.

Step 5: Keep records. Retain copies of the water authority's invoice, your issued invoice to the tenant, the date it was delivered (email delivery with read receipts helps), and payment records. These are the documents you need if the matter escalates to a tribunal.

A practical record-keeping note: some property management platforms allow you to attach scanned water bills directly to a property record. If yours does, use this feature — it creates a searchable audit trail without relying on a separate filing system.

One of the most overlooked elements of water usage charging is also one of the simplest: documenting the water meter reading in both the entry and exit condition reports.

A recorded entry meter reading establishes a baseline from which all usage charges during the tenancy are calculated. An exit meter reading establishes the endpoint. Together, they provide an unambiguous record of the tenant's total consumption — and they eliminate any dispute about whether a large bill reflects genuine tenant usage or an underlying plumbing fault present before the tenancy began.

Most state-prescribed condition report forms include a field for the water meter reading. If the form you are using does not, add it as a note in the utilities or external areas section.

When recording meter readings:

• Note the full reading at the date and time of inspection
• Photograph the meter display and attach the photo to the relevant section of the condition report — this creates a timestamped, geolocated record that is significantly more defensible than a handwritten note
• For digital inspection tools, attach the photo directly to the utilities or services section so it is permanently linked to the inspection record

The meter reading also matters in mid-tenancy repair scenarios. If a property develops a plumbing leak and the landlord arranges repairs, a meter reading taken immediately before and after the repair period helps separate the usage attributable to the leak (landlord's cost) from the usage attributable to normal tenant consumption (potentially recoverable). Without these readings, the entire elevated bill is likely to be treated as the landlord's problem.

For property managers using ConditionHQ, attaching a meter photo to the entry inspection creates a timestamped record tied directly to the condition report — useful not just for water billing but for any future dispute about the property's condition and services at the start of the tenancy.

Several situations mean water usage charges remain with the landlord, even where the basic metering and agreement conditions are met. Being aware of these helps avoid issuing incorrect invoices:

The property no longer meets water efficiency standards (NSW, VIC, QLD). If a showerhead has been replaced by the tenant with a non-compliant fitting, or an original compliant fitting has degraded, the efficiency condition is no longer met. The landlord should arrange replacement and cannot charge for usage during the period of non-compliance. On discovery, arrange the repair promptly and document the replacement date.

A plumbing fault inflated the bill. If a leaking tap, running toilet, or burst pipe caused the meter reading to increase beyond normal consumption, the tenant is not liable for the portion attributable to the fault — particularly if the landlord was aware of or responsible for fixing it. If the fault was the tenant's responsibility to report (and they failed to), the apportionment becomes more complex and may require tribunal determination.

The billing deadline has passed (Queensland). If the four-week window from receipt of the supplier's invoice has lapsed, the Queensland property manager cannot charge for that billing period. The loss is not recoverable.

The property is on a shared meter. Discovered after the fact, this disqualifies the entire charging arrangement for that property. The fix is practical: arrange for the water authority to install an individual meter, and only begin charging once individual metering is confirmed.

The tenancy agreement does not include the clause. If the executed agreement was signed without the relevant water usage provision, usage charges cannot be imposed mid-tenancy. The clause cannot be added retrospectively without the tenant's written agreement.

Understanding these limitations in advance — and building checklists to verify them before billing — is more efficient than resolving disputes after the fact.
