Welcome to OSM and thanks for your edits. FYI - Phone numbers in Australia should be added to OSM according to the following format with the country and regional code +61 x xxxx xxxx, +61 xxx xxx xxx for mobiles or use the phone:AU key if a 1300 or 1800 number.
For freecall numbers that work whilst overseas (ie 13 13 13) use +61 XX XX XX as per the wiki guidelines osm.wiki/Australian_Tagging_Guidelines/Australian_features#Phone_Numbers . I have just updated a recent addition that you made to OSM – Cheers

FYI - When entering the state in an address the preferred format is uppercase and abbreviated (ie QLD).
