I had exactly the same issue, our last quarterly electricity bill came to over $1K when there are 2 adults and a 5 year old in a 2 bedroom apartment. The past 2 years each quarter was no more than $450 a quarter. I was outraged and tried to dispute to outcome. AGL said our usage had doubled and the KW prices had also increased. AGL seems to have a lot of these over charges and we do need to go to the Ombudsman.
