A list of physiographic units in Australia that provide a consistent framework for mapping soils and landforms at national and regional scales, compiled at a continental scale. The list was defined by Pain et al. (2011; https://www.clw.csiro.au/aclep/documents/PhysiographicRegions_2011.pdf)* and built on the work of Jennings and Mabbutt (1986). It recognises a subdivision of the Australian onshore continent into three physiographic divisions, 23 physiographic provinces and 220 physiographic regions.

The State of Western Australia is divided into various Mineral Fields that represent administrative land subdivisions under which mining is administered in the State according to Section 16 of the Mining Act 1978. Some mineral fields are further subdivided into Districts. Mineral field and district boundaries can be changed by proclamation under the Mining Act 1978 — the listing provided is current as of June 2023. Each mineral field or district is characterized by a two-digit prefix code used for map representations and tenement indexing.

The coordinate reference systems (geographic and projected) used and referred to within Western Australia. It includes historical and current reference systems, Universal Transverse Mercator (UTM) zones, and, where applicable, notations based on the EPSG registry (https://epsg.io/). Some concepts are included to account for legacy data/maps with limited information.

Characterization of the type of physiographic units used by the Geological Survey of Western Australia for mapping regolith and landforms in the State. A physiographic units is defined as 'A named geomorphological entity with internal coherence in its landform characteristics and landform evolutionary history. At the lowest levels, physiographic units reflect the underlying geology and have similar groupings of regolith materials that are related to the landform types, their evolution, and the underlying bedrock.' Physiographic unit types are based on the classification of Pain et al.

Names and physical locations of facilities housing Geological Survey of Western Australia (GSWA) collections of physical objects. The list includes buildings or designated parts of buildings, as well as external storage facilities. 

Names and physical locations of metropolitan and regional offices of the Department of Mines, Industry Regulation and Safety (DMIRS). The list includes venues with or without public access or information facilities, and highlights the location of Western Australia core libraries and offices of the Geological Survey, as well as Mine Inspectorate and Mining Registrar offices. 

Indicates the nature of the borehole start point location, i.e. the general setting and type of surrounding where the borehole is positioned (e.g. onshore, offshore, etc.).

A description of the intended configuration and trajectory of a borehole, covering concepts from the energy and mineral resources industry. Note that most of the concepts in this vocabulary apply to both the process of drilling (e.g. directional drilling), as well as to an actual borehole (e.g. directional well), even if the definitions in this vocabulary focus specifically on the latter.
