Postcode level data is the finest level of aggregation that the dashboards currently offer.  You can select a specific postcode from the filters and details for that postcode will be displayed.  Remember, that at least 10 certificate records are required before data results are displayed, so for some postcodes the data is limited and may return a blank result.  Over time as data increases these postcodes will become visible.

Star Rating and Floor Area Ranking by Postcode

The following chart ranks both star rating and floor area by postcode within a State. Clicking on the top of either column will reorder the data numerically, highest and lowest. You can also search for a specific postcode or location using the Highlight Postcode or Highlight Location options on the right hand side.
