How to Trade Water in NSW: A Step-by-Step Guide
Trading water in New South Wales follows a defined process managed by WaterNSW. Whether you're selling surplus allocation or buying to cover a shortfall, here's exactly how it works — including the forms, fees, and rules that trip people up.
The Legal Framework
Two instruments govern NSW water trading:
The Water Management Act 2000 (WMA 2000) establishes the system of water access licences and the rules for trading them.
Water Sharing Plans (WSPs) set the specific rules for each water source — where and when you can trade, extraction limits, and environmental flow requirements. There are separate WSPs for each regulated river, unregulated system, and groundwater source. Always check the WSP for your specific water source before assuming a trade is possible.
WaterNSW processes trade applications. The Department of Planning and Environment — Water handles policy and planning.
Trading Allocations (Temporary): The Process
Step 1: Find a counterparty and agree terms. You need a buyer or seller, a volume (in ML), and a price per ML. You can negotiate directly with other licence holders or use a water broker to access a wider market and get current price guidance. For irrigators in the Murrumbidgee valley, Murrumbidgee Rural Agencies (MRA) specialises in allocation trading, carryover sourcing, and managing the full transaction process through to WaterNSW approval.
Step 2: Complete the application form. For regulated surface water, you'll use a Form 71 (assignment of water allocation). Download a fresh form from the WaterNSW trading page for every trade — reusing forms causes processing errors because each has a unique reference number.
Step 3: Pay the fee. The processing fee for regulated surface water is $59.56 (GST free). For unregulated water and groundwater, it's $58.16 (GST free). Pay via the Westpac PayWay portal using Biller Code 228627 and the reference number from your form.
Step 4: Submit. Email your completed form to water.trade@waternsw.com.au (one application per email). Include your Supply Work Contract (SWC) reference number in the subject line — this speeds up processing and makes enquiries easier.
WaterNSW assesses the application against the relevant Water Sharing Plan rules. If approved, the allocation is transferred between accounts.
Key Rules and Gotchas
Record-keeping (from 1 July 2024): All information on trade forms — including the reason for trade and the price — must be accurate and complete. You're required to keep supporting records for a minimum of five years. This is a compliance obligation, not a suggestion.
End-of-season deadlines: Strict cut-offs apply for trades lodged near June 30 (end of the water year). Late applications may be subject to impact assessments that can reduce your approved volume or result in refusal. Don't leave it until the last week.
Third-party consent for groundwater: Some groundwater trades require you to obtain consent from nearby bore owners who may be impacted. WaterNSW will tell you if this applies, but it can add weeks to the timeline.
Variable usage charges: If the buyer's licence isn't linked to a NSW Works Approval, additional charges may apply. Contact the WaterNSW Customer Service Centre to confirm before submitting.
Trade updates: Always check the "water trade updates" section on the WaterNSW website before lodging. It lists current restrictions, zone closures, and rule changes that could affect your trade.
NSW vs Victoria: Key Differences
If you've traded in Victoria, note some important differences in NSW:
- NSW uses Water Access Licences (WALs) rather than Victoria's unbundled Water Shares/ABA/WUL system
- The approval body is WaterNSW, not the Victorian Water Register
- NSW entitlement categories include high-security and general-security licences (similar concept to HRWS/LRWS but different naming and allocation rules)
- Interstate trades between NSW and Victoria are governed by the Murray-Darling Basin Agreement and subject to a 200 GL annual cap on tagged trade
For a walkthrough of the Victorian system, see our guide to water trading in Victoria. For a comparison of entitlement types, see water entitlements vs. water allocations.
Using a Broker
A broker handles the paperwork, ensures compliance with the relevant WSP, and can access a broader network of buyers and sellers than you'd find through direct negotiation. Since the Water Markets Intermediaries Code took effect in 2025, all brokers must hold client funds in statutory trust accounts, carry PI insurance, and be registered with the ACCC.
Through the Aquifa platform, you can connect with specialist brokers matched to your region — including MRA for the Murrumbidgee valley and Integra Water Services for the Victorian Goulburn and Murray systems. See our guide on choosing the right water broker for what to look for.
