Reforms to the Water Act 1992 have opened a new chapter for nt water trading, with licence holders now able to trade water anywhere within the Northern Territory as long as the trade remains within the same water resource. The change removes previous restrictions that confined trades to water allocation plan areas, expanding the market and improving flexibility for licence holders.
The expanded framework enables water to move to where it can deliver the greatest value without increasing pressure on the Territory’s water systems. Trades must stay within the same groundwater aquifer or surface water resource, ensuring each transaction remains compatible with sustainable extraction limits. This is a significant shift for regions such as Darwin Rural, where some resource areas are fully allocated even though substantial portions of licensed water remain unused.

How the changes improve efficiency and water access
The Territory’s water use patterns show that more than half of licensed water remains unused each year due to seasonal variability, crop rotation, market conditions or operational changes by individual licence holders. Allowing broader trading means this unused water can be accessed by new or expanding businesses that may not otherwise secure a licence under current limits.
Under the revised system, any licence holder across the Territory may apply to trade part of their entitlement with another licence holder drawing from the same resource. All trade applications require approval from the Controller of Water Resources, who must ensure no trade adversely affects neighbouring properties, existing users or environmental values. This oversight helps maintain a consistent and transparent process while supporting responsible access.
Importantly, trading does not increase total water use. Any increase to one licence must be offset by a matching reduction from another licence accessing the same water resource. This maintains the integrity of sustainable extraction limits while improving utilisation rates.
Supporting long term planning and development
The reforms lay the groundwork for a more responsive water market that supports economic expansion while maintaining safeguards for water-dependent ecosystems. By improving access to existing entitlements, the reforms help businesses plan with greater certainty and reduce administrative barriers associated with seeking new allocations.
The Territory Government expects the changes to encourage investment in industries that rely on secure water supply, including agriculture, horticulture and tourism. At the same time, the expanded nt water trading framework provides a mechanism for more efficient use of licensed volumes across the Territory’s diverse and highly variable environments.
