Port Augusta Fly Ash

The Hon. R.L. BROKENSHIRE (15:02): Supplementary question: will the minister check with the offices to establish and then advise the house whether there are concerns with the composition of the fly ash and that it may well not be suitable for standards required to use in bricks?

The Hon. I.K. Hunter: It's not fly ash.

The Hon. K.J. MAHER (Minister for Employment, Minister for Aboriginal Affairs and Reconciliation, Minister for Manufacturing and Innovation, Minister for Automotive Transformation, Minister for Science and Information Economy) (15:02): I'm happy to check and, as the Hon. Minister Hunter interjects, it's not fly ash, that's what comes out the top of the power station, this is bottom ash which is from the bottom of the power station, but taking that into account, the bottom ash in ash dam. I will check if there has been any independent testing of it, but it's usually not the government's or the company's or Flinders Power's or Alinta's role to test ash to see if it is suitable for a commercial application. It is generally the case that if there is a company who wishes to use that resource, they get it independently tested. I'm not aware that they've done that, but I will check to see if they or anyone else has.
