Southern Murray–Darling Basin Water Market Update

Temporary water prices in the Murray–Darling Basin are firming amid unchanged allocations, a dry autumn outlook and emerging El Niño risk. With storages near 2019 levels and structural supply tightening, price pressure remains biased to the upside without meaningful rainfall.

The Southern Murray-Darling Basin water market remains firm following the 16 February allocation update, which delivered no further increase to allocations. While there had been some residual hope for incremental improvement in parts of the system, most market participants were not anticipating a meaningful uplift at this stage of the season. The confirmation of unchanged allocations has therefore reinforced – rather than surprised – prevailing sentiment.

Climatic conditions remain a central influence. The current outlook is dry, with forecast models pointing to below-average rainfall across much of the Basin through April to June. A transition toward El Niño conditions by late autumn is increasingly reflected in seasonal guidance. While forecast confidence at this time of year is never absolute, the directional bias toward drier conditions is shaping forward expectations and risk management decisions.

Temporary water prices have trended upward in response. With limited prospects of additional allocation this season and uncertainty surrounding autumn break timing, buyers are showing increased urgency in securing cover. Sellers, meanwhile, are displaying greater discipline, particularly those managing carryover into what could be a tighter 2026-27 water year.

Unforecast rainfall could soften pricing in the short term. A late-summer or early-autumn event would likely prompt opportunistic selling and provide a brief window of relief for buyers. However, without sustained inflows through winter and spring, any price retreat would likely prove temporary. Structural supply constraints and reduced system buffers would remain in place.

Storage levels across the Southern Basin are broadly comparable to the same point in 2019. The 2019–20 water year ultimately saw significant price escalation as dry conditions persisted and allocation outlooks deteriorated. While no two seasons unfold identically, the storage starting point warrants attention, particularly given the current climatic trajectory.

Overlaying the seasonal picture is ongoing Commonwealth water recovery under the Restoring Our Rivers Act. Government buybacks and related recovery measures continue to reduce consumptive pool availability. In wetter cycles this impact can be absorbed more readily; in tightening conditions it amplifies market sensitivity and accelerates price response.

Taken together, the market is entering the back half of the 2025–26 water year with a cautious tone. Allocation upside appears limited, the climate outlook is skewed dry, and structural supply settings remain restrictive. Unless autumn conditions materially exceed expectations, pricing pressure is likely to remain biased to the upside, with volatility increasing as attention turns to winter inflows and the 2026-27 outlook.
