Review of route selection

During public consultation on the EIS, a number of landholders objected to the alignment of a 100-kilometre section of the transmission-line route.

The section - which came to be known as the Costello to Landsberg Alignment - lies between the properties of PM Costello and RG & JM Landsberg.

Broadly, the landholders were concerned that:

  • the transmission-line route was incompatible with existing and envisaged agricultural land uses
  • they were not properly consulted on the alignment of the route

In response, the Coordinator-General ordered a review of the route selection process and methodology.

Consultants Golder Associates conducted the review, which looked at:

  • terms of reference for the EIS
  • route selection process and methodology, including a comparison with the process and methodology recently used by Powerlink Queensland to select a transmission-line route
  • transmission line's potential impacts on land-use practices
  • consultation conducted during the route selection process.

The review report concluded that:

  • the route selection report compiled by consultants Resource and Land Management Services could have been structured more clearly
  • overall, the route selection process and methodology were valid, using reasonable criteria for route selection
  • extensive consultation was undertaken, including with all the landholders along the Costello to Landsberg Alignment.
