Mapping in Power BI

Hi JP8991 

The reference layer overlays an uploaded GeoJSON file on top of the map. For the original map, you still have to provide multiple sources of location information (such as country/region, state, city, street address and zip code) in the Location field to guarantee more accurate results and eliminate ambiguity that would prevent a specific location to be determined. You can also add latitude and longitude data of areas to improve the accuracy. 

In your case, you are using SA3 codes. Statistical Areas Level 3 (SA3) are geographical areas built from whole Statistical Areas Level 2 (SA2). SA3s are designed to provide a regional breakdown of Australia. I'm not sure if Azure Map can recognize SA3 codes as effective Geocoding in Australia. From current result, it seems failed. You may try adding a Country column with value "Australia" or AU in your data table, categorize it as Country/region and add it to Location field too. If this still doesn't help, you may have to use other location fields or latitude/longitude fields instead of the SA3 codes to improve the accuracy.
