Appeal to the South Australian Civil and Administrative Tribunal

On 8 September 2021, Robusto Investments Pty Ltd lodged an application with the South Australian Civil and Administrative Tribunal (Tribunal) for a review of the varied Regulatory Determination, issued by the Commission on 26 August 2021 after its internal review of the original Regulatory Determination, made in May 2021.

This matter is now before (and will be managed by) the Tribunal in accordance with the South Australian Civil and Administrative Tribunal Act 2013.

At this time, the maximum revenue and maximum prices set by the Commission under the varied Regulatory Determination it issued on 26 August 2021 remain in effect. To the extent it is permitted, the Commission will provide any necessary updates as the review process before the Tribunal progresses.

Robusto Investments - Review application decision

On 23 June 2021, Robusto Investments Pty Ltd lodged an application for an internal review of the price determination that applies to it, made by the Commission on 25 May 2021. 

In accordance with section 31 of the Essential Services Commission Act 2002, the Commission has completed that internal review, with the outcomes advised in the ‘Drinking Water Regulatory Determination: Review Application Decision - Statement of Reasons’. 

The overall outcome of the review is a reduction in the maximum allowed revenue which Robusto may recover over the determination period 1 April 2021 to 30 June 2022, and a reduction in the maximum prices that Robusto may charge its customers. As a result, the maximum price rise could be up to 15 percent as compared to the prices in place prior to 1 April 2021, rather than the maximum price rise of up to 22 percent allowable under the Commission’s original determination (which took effect from 1 April).
