Auditor panel

The Retailer Reliability Obligation (RRO) requires that - if the obligation is triggered - liable entities (relevant market customers and opt-in customers) report their net contract position to the AER, with contracts adjusted based on their relative 'firmness'. Standard qualifying contracts are to be adjusted using a default firmness methodology, and non-standard qualifying contracts are to be adjusted using a bespoke firmness methodology developed by the liable entity.

Liable entities are required to have their bespoke firmness methodology, and the way they have been applied, approved by an independent auditor on the AER's auditors panel.

Rule 4A.E.5 of the National Electricity Rules requires the AER to establish and maintain a panel of auditors. The Auditor Panel Handbook acts as a supplementary guide to the Interim contracts and firmness guidelines. It specifies governance arrangements, including how we will establish and maintain the Auditors Panel, and our monitoring and oversight of the Auditors Panel.

Information on how to apply is contained in the Auditor Panel Handbook. All applications should be emailed to For any queries about the application process please email
