Correction, 17 August 2026. This story originally described the AGL penalty as settled: the table called it “Decided. A Federal Court order” and the text said it was “the only one a court has decided”. That was wrong, and it was wrong about the one thing this piece is built to get right. The same AER report we worked from records that AGL appealed both the decision and the penalty to the Full Federal Court, that the appeal was heard on 27 and 28 November 2025, and that judgment was reserved. A first-instance penalty under appeal is not a settled outcome, and stating otherwise about a named company is exactly the error the piece warns against three paragraphs later. The standfirst, the table, that sentence and the page description are all corrected. We do not know whether judgment has since been delivered; the report is current only to 30 June 2026, and we would rather say that than guess. No figure has changed and the Alinta and Origin descriptions were already accurate.
Centrepay lets a person on a Centrelink payment have bills deducted automatically before the rest of the money reaches them. It is used precisely because it makes essential bills predictable. That is also what makes overcharging through it different in kind from overcharging anyone else: the money leaves before the customer sees it, and the person it leaves is on income support.
The National Energy Retail Rules put obligations on retailers about exactly this, and the regulator's new report shows what happened when they were not met.
What the report records
The distinction between these three matters is not decoration, so it is set out plainly.
| Retailer | Outcome | Status |
|---|---|---|
| AGL | Ordered to pay $25 million in penalties, 2024 | Under appeal. AGL appealed the decision and the penalty; heard 27-28 November 2025, judgment reserved |
| Alinta | Paid $1.089 million following 15 infringement notices | Alleged. Paying an infringement notice is not an admission |
| Origin | Proceedings instituted in the Federal Court | Before the court. Allegations, untested |
The AGL matter is the only one in which a court has imposed a penalty, and it is not finished: AGL appealed both the decision and the penalty to the Full Federal Court, the appeal was heard on 27 and 28 November 2025, and the report records that judgment was reserved. In 2024 the Federal Court ordered AGL Retail Energy Limited and three other AGL subsidiaries to pay $25 million for failing to comply with overcharging obligations under the Retail Rules, and for failing to have systems and procedures in place to monitor compliance with them.
The Alinta matter is an allegation the company has resolved by payment rather than contested. It paid $1.089 million after the regulator issued 15 infringement notices for allegedly failing to comply with the overcharging obligations. The report says the alleged conduct affected customers across NSW, Queensland and South Australia between April 2019 and September 2024, with amounts overcharged per customer running from about $100 to nearly $9,750, and that Alinta allegedly failed to inform and refund affected customers inside the timeframes the Rules require.
The Origin matter is live and nothing here should be read as a finding. The regulator has instituted Federal Court proceedings, and what follows is what it alleges. It says the conduct affected more than 3,400 electricity and gas customers who had closed their accounts and fully paid everything they owed, that it amounted to more than 77,000 breaches, that Origin retained more than $2.5 million from affected customers, and that one customer was overcharged by more than $11,000 over almost two years. Those are allegations before a court. Origin is entitled to answer them there.
What it means for a household here
None of these matters happened in the Hunter specifically, and we are not going to pretend otherwise. The connection is simpler and more useful than a local incident: the Alinta conduct is recorded as affecting NSW customers, and every household in this region buys electricity from a retailer bound by the same Retail Rules. A billing obligation that three large retailers have now been pulled up on is not a distant problem.
The practical point for anyone paying by Centrepay, or helping someone who does: the amounts in the Alinta matter started at about $100, and the largest single case the regulator alleges against Origin built up over almost two years. Automatic deduction is convenient exactly because you stop watching it, and these matters are about closed accounts and overcharges that ran unnoticed. A bill that is paid without being read is the one worth reading.
Our view, labelled as such
Three enforcement actions against three major retailers over the same obligation is not three coincidences, and the regulator clearly does not think so either: it has put them in the same report under the same heading.
What that pattern suggests is a systems problem rather than a run of individual errors, which is also what the AGL orders found, since part of that penalty was for not having procedures capable of monitoring compliance. The report's own weighting points the same way. Family violence obligations are mentioned 24 times across it and life support customers 20 times, which describes a regulator concentrating its attention on the customers who can least afford a mistake. That is the right priority. The open question, and it is not one this report answers, is whether enforcement after the fact is doing anything to stop the next occurrence, or whether three actions in three years is simply the cost of doing business.
