Allocation trade involves transferring a volume of water allocation from a seller to a buyer. Allocation trade is only permitted when the volume of unused allocation available in the seller’s allocation account is greater than or equal to the volume of the trade.

Holders of water allocation are able to make an application to their water corporation to trade it. The water corporation will approve the application if it is complete and meets local trading rules.

Permitted trades include allocation trades between trading zones within Victoria and interstate. Trading rules are assessed based on the source of the water allocation. This may be different to where the allocation is used depending on whether the allocation is tagged to a different location.

Prior to unbundling the concept of allocation did not exist, although temporary trade of entitlement is often used as a comparable measure for historic trade of allocation in declared systems in Victoria.

Allocation trading history

For example, you can find volumes traded within, into and out of the trading zone in the current season, the number of trades, price statistics on those trades, and a list of all trades.

If you plan to trade water out of the Murrumbidgee (from trading zone 13), you or your broker will need to keep an eye on available opportunity under the Murrumbidgee trade out limit by visiting WaterNSW’s website.

Allocation trade from New South Wales to Victoria is limited to a net annual volume of 200 GL, or the volume that keeps the risk of spill in the Murray system below 50%, whichever is the lesser.

Understanding Trade Limits

A new tool is now available to help you better understand and visualise trading limits and the available trade opportunities in northern Victoria, and how these may affect your allocation trades.

You can also use this Trade Limits tool to help you to understand current and historic trading opportunities and how they applied to your previous trades.

 
Trading Rules generally permit trade of allocation from one trading zone to other trading zones provided that the traded water can readily flow to the destination trading zone. The trading rules also permit trade in the opposite direction ("back-trade") if previous forward trade has opened up an opportunity.

In order to protect third parties and the environment, some trade limits apply. You can also find some information on limits on trade between valleys in the fact sheet and explanatory note available below.

Allocation Trade Data

Here you can access a list of all allocation trades which occurred within the regulated water systems for a selected region and year.

You can use this data for your own analysis. For example, to analyse the volumes of trade which occurred between private water holders, environmental water holders and water corporations; or, to assess the total volume of commercial trades in a particular year.
