This dataset contains the major roads for Australia, extracted from the OpenStreetMap project on December 2011 by CloudMade.
From the complete set of roads in the OpenStreetMap shapefile only major roads were extracted. This created a smaller high performance shapefile.
In ArcMap loaded the AU_CloudMade_OpenStreetMap-Dec-2011 shapefile then used the Analysis Tools/Extract/Select tool to extract the major roads.
