This WMS is the national database of Australia. It will allow you to view and make maps with a diversity of layers. It features two WMS bundles of themes; with WMS URLs: "http://www.ga.gov.au/wms/getmap?dataset=national&request=capabilities" is for National Geoscience Datasets, and "http://mapconnect.ga.gov.au/wmsconnector/com.esri.wms.Esrimap?Version=1.1.1&Request=getcapabilities&Service=WMS&Servicename=GDA94_MapConnect_SDE_250kmap_WMS&" is for National Topographic Datasets (Jim P., July 2009).

Interactive mapping interface with links to data download from multiple sources. I found some download links to be more understandable than others. (Jim Proctor, Oct 2009)

PDF file providing overview of data used for 2006 Environmental Performance Index, including raw values for included countries and brief descriptions of how data were collected/measured. From site: "By identifying specific targets for environmental performance and measuring how close each country comes to these established goals, the Pilot 2006 Environmental Performance Index (EPI) provides benchmarks for current national pollution control and natural resource management results. The issue-by-issue and aggregate rankings facilitate cross-country comparisons both globally and within relevant peer groups.…The EPI centers on two broad environmental protection objectives: (1) reducing environmental stresses on human health and (2) protecting ecosystem vitality." | GIS_Data>ENVSData>Other_Sites>Global>Global_EPI>CNTRY_EPI_joined (Jim Proctor Fall 2008).
