Potential future urban water demand in the Cairns area and the stimulation of irrigated agricultural growth in the region may require water storage augmentation.


The proposal is investigating the following options for augmented water supply for Cairns and irrigated agriculture in the nearby area:

  • augmenting/enhancing the existing water supply system
  • optimising water trading within the catchment and ‘repurposing’ current water allocations
  • converting water losses from existing water transport infrastructure (e.g. transfer channels) to new water allocations
  • construction of Nullinga Dam.

The project is expected to increase availability of water and enhance agricultural development opportunities.
