Here in Sydney, our power meters are located on the outside of the house, and read every quarter, by a meter reader who goes to each house to read the meter/s.
Being the old curmudgeon that I am, I refuse to use direct debits for any of that sort of thing for the reason that they can "adjust" what they take out of your account, without your permission. I pay by cash, as it is non traceable

In January this year, we got a letter, old style, from the power company, stating that our meters were due for maintenance or replacement.
I rang to find out what the go was, and was told that as the meters were "old" (agreed, as they were here when we moved in in 1971!) they would probably need replacing. I asked would they be "smart meters" , and was told they would be "like for like", but probably digital, not analog.
I was also told that I was not on a "plan" which would require a smart meter.
As I understand it, the Victorian government is forcing the replacement of dumb meters with "smart" meters, but NSW has not been that stupid, (yet)
