How to do a desk check

  1. Type your address into Google maps and see where the marker is placed.  There is a good chance, if you are a rural property, the marker is not placed anywhere near where your house is. Take a screenshot of the map where the marker is and put the screenshot in a word document (the snipping tool is an easy way of selecting part of your screen.

It is to be used only as a guide, and for preparing a file to send to NBN, so they can consider your case.
