The Melbourne Institute already produces a month-to-month Australian inflation gauge but it surely isn’t a lot quoted, maybe for that reason.
An excessive amount of data?
One plus (or minus) with the month-to-month index is that it will likely be revised within the gentle of recent or delayed data. The quarterly index is hardly revised, as a result of it’s utilized in contracts and the indexation of presidency advantages.
