Wyber v Chief Executive, Primary Industries Corporation

The case of Wyber v Chief Executive, Primary Industries Corporation involved two appeals under the Water Resources Act 1989. The appellants, John Bruce Wyber and John Ross Hudson, contested the conditions attached to waterworks licences issued to Hudson for works on Neabul Creek, which passes through his property, Maranoa Downs. Hudson had applied for licences to construct two dams, Dam No. 2 with a capacity of 60 ML and Dam No. 1 with a capacity of 200 ML, on Neabul Creek. Wyber, the owner of Abernethy downstream of the dams, objected to the licences due to concerns about the impact on the waterhole on his property, Ten Mile Hole. The appeals were heard together with the consent of the parties.

The central legal issues before the court were whether the conditions imposed on the licences were reasonable and adequate to protect the interests of downstream landowners while recognising the riparian rights of Hudson. Specifically, the court had to determine if the conditions requiring the installation of outlet pipes in the dams and the prohibition on the installation of control gates were appropriate. Additionally, the court needed to consider the adequacy of the flow conditions specified in the licences to ensure sufficient water reached downstream properties.

The court found that the original licence conditions were not sufficient to protect the interests of downstream owners, particularly in relation to the size of the outlet pipes and the flow conditions. After reviewing the evidence and conducting further investigations, the department recommended amendments to the licences to better manage the water flow and protect the interests of downstream properties. The court accepted these recommendations and allowed the appeals to the extent necessary to implement the recommended changes. The court varied the licences to reduce the diameter of the outlet pipe on Dam No. 2 and increase it on Dam No. 1, and amended the flow conditions to ensure adequate water release to downstream properties.

In summary, the court allowed the appeals and varied the licences to better protect the interests of downstream landowners while recognising the riparian rights of Hudson. The court ordered the modifications to the outlet pipe sizes and flow conditions as recommended by the department, ensuring a balanced approach to managing water resources on Neabul Creek.
