NEXIS (National Exposure Information System) Residential Dwelling Density is a set of four raster layers representing the density of residential dwellings across Australia at different scales and resolutions. Resolutions include 2km, 1km, 500m and 100m. The Australian Bureau of Statistics (ABS) defines dwelling units as self-contained suites of rooms including cooking and bathing facilities and intended for long-term residential use. Such dwelling units include houses-detached buildings used for long-term residential purposes-and other dwellings including flats. This product is based on NEXIS version 15 (2024) data. Resolutions: 1. Number of residential dwellings per 100sqm. Visible at zoom scales 1:250,000 minimum with no maximum. 2. Number of residential dwellings per 500sqm. Visible at zoom scales 1:700,000 minimum with 1:250,001 maximum. 3. Number of residential dwellings per 1km square. Visible at zoom scales 1:3,000,000 minimum with 1:700,001 maximum. 4. Number of residential dwellings per 2km square. Visible at zoom scales with no minimum and 1:3,000,001 maximum

This product is an aggregation of the Australian Exposure Information Platform (AEIP) by the Statistical Areas Level 1 (SA1), 2016 SA1 boundaries. The aggregated information is from version 6 of the Australian Exposure Information Platform. In 2002 Geoscience Australia (GA) embarked on the development of the National Exposure Information System (NEXIS) project in response to the Council of Australian Governments (COAG) reform commitment on Australian’s ability to manage natural disasters and other emergencies. Public access to NEXIS has been limited to products based on Local Government Areas or ABS Statistical Areas. In 2013, the Bushfire and Natural Hazard Cooperative Research Centre, Geoscience Australia led a three year research project in collaboration with University of Melbourne and the University of Canberra, to document a comprehensive Natural Hazard Exposure Information Framework. The objective was to fully describe and categorise exposure information elements in a consistent framework to be used as a reference for developing future exposure information systems. In 2018, in partnership with the Bushfire & Natural Hazard CRC, Geoscience Australia has made available the Australian Exposure Information Platform (AEIP). The aim for AEIP was to make nationally consistent exposure information, directly accessible to key stakeholders involved in emergency management situation awareness, risk assessments, impact analysis research, and disaster management. The Platform combines the extensive work from NEXIS and the comprehensive ‘Natural Hazard Exposure Information Framework’, by providing user’s direct access to national Exposure Information. It includes 'elements' on building, businesses and people; public facilities and infrastructure assets; agricultural commodities, and environmental holdings within Australia. Exposure Reports provides a detailed statistical summary of the 'elements', within a user defined area of interest. The AEIP exposure information provides a summary of building and agricultural aggregated information. For more detailed building information, see NEXIS Building Exposure linked records.

<div>Knowledge of the nature of buildings within CBD areas is fundamental to a broad range of decision-making processes, including planning, emergency management and the mitigation of the impact of natural hazards. To support these activities, Geoscience Australia has developed a building information system called the National Exposure Information System (NEXIS) which provides information on buildings across Australia. Most of the building level information in NEXIS is statistically derived, but efforts are being made to include more detailed information on the nature of individual buildings, particularly in CBD areas. This is being achieved in Parramatta through field survey work.</div>
