The objectives of hydrogeologically mapping the Murray basin were to generate a set of maps at 1:250 000 scale to: - show the influence of groundwater on land salinisation and surface water salinity - delineate useable groundwater resources - highlight present and potential salinity hazard and - enhance community awareness and understanding of groundwater systems and processes and provide a groundwater data-base for the Murray Basin to facilitate land and water resource management decisions. The production of the Murray Basin Hydrogeological Map Series was a major coordinated Government action in the management of groundwater to combat degradation through salinisation and enable sustainable land and water use in the Murray Basin. The Hydrogeological Map Series was a collaborative effort between the various water authorities of South Australia, Victoria and New South Wales. Explaining this product in detail is an article by Evans, W.R. 1992, "The Murray Basin Hydrogeological Map Series", Water pp. 20-23.

This product is prepared in conjunction with Australia Post and includes the geographic coordinates of the approximate centre of each postcode area. Postcode centroids are commonly used to calculate approximate distances between postcode areas. Scale is 1:10 000 in urban areas, and 1:25 000 to 1:1m in rural areas.

This product is prepared in conjunction with Australia Post. The 1991 Census Modified Postcode Boundary product has been designed for those who wish to use geographically accurate postcode boundaries with the digital topographic data included with the ABS CDATA91 and CMAP91 products. Scale is 1:10 000 in urban areas, and 1:25 000 to 1:1m in rural areas.

This product is prepared in conjunction with Australia Post. This is a small dataset which provides an easy to use and affordable entry to the use of postcodes with desktop computer mapping. This file can be used to display the approximate shape of postcode area and the relationships between postcode areas. Scale is 1:10 000 in urban areas, and 1:25 000 to 1:1m in rural areas.

At this scale 1cm on the map represents 1km on the ground. Each map covers a minimum area of 0.5 degrees longitude by 0.5 degrees latitude or about 54 kilometres by 54 kilometres. The contour interval is 20 metres. Many maps are supplemented by hill shading. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours, localities and some administrative boundaries. Product Specifications Coverage: Australia is covered by more than 3000 x 1:100 000 scale maps, of which 1600 have been published as printed maps. Unpublished maps are available as compilations. Currency: Ranges from 1961 to 2009. Average 1997. Coordinates: Geographical and either AMG or MGA coordinates. Datum: AGD66, GDA94; AHD Projection: Universal Transverse Mercator UTM. Medium: Printed maps: Paper, flat and folded copies. Compilations: Paper or film, flat copies only.
