The Land tenure of Australia 2010–11 to 2020–21 data package consists of seamless continental rasters showing Australia’s land tenure, and land tenure change, for three time periods 2010–11, 2015–16, and 2020–21. Using a 4-tiered hierarchical classification, the datasets show where land is owned, leased, reserved or unallocated to a defined purpose in Australia. The datasets were constructed by combining jurisdictional land title information from digital cadastral databases or their equivalents with Indigenous land grant instruments areas. The data package contains for each of the 3 time periods an independent raster and data caveat raster of known uncertainties in the product, plus 4 combined change rasters. The 5-yearly data is at a resolution of 250 by 250 metres. The Land tenure of Australia 2010–11 to 2020–21 data package is a product of the Australian Collaborative Land Use and Management Program. This data package replaces the Land tenure of Australia 2010–11 to 2015–16 data package, with updates to these time periods.

The Land use of Australia 2010–11 to 2020–21 data package consists of seamless continental rasters of land use at the national scale which provides the spatial representation of how Australia’s land resources are used. Data is for 2010–11, 2015–16 and 2020-21, and the associated changes between the years. Land use is specified according to the Australian Land Use and Management (ALUM) Classification version 8. The Land use of Australia 2010–11 to 2020–21 data package is a product of the Australian Collaborative Land Use and Management Program.

## **Abstract** This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied. Contains boundary and attribute information for parcels of public, private and Aboriginal lands in Australia. Data are sourced primarly from government gazette notices, cadastral maps and plans. A nominal scale of around 1:5 million and a minimum 50 square kilometre threshold limit for land parcels was used in the generalisation of this product from the National Public and Aboriginal Lands data. Data is suitable for GIS applications. This map shows public and private land tenure, including Indigenous land for the whole of Australia at a scale of 1:4.7 million. The land tenure boundaries depicted on this map generally define broadly classified areas greater than 50 square kilometres. Indigenous land areas between 0.1 and 100 square kilometres are shown more comprehensively by symbols. The information on this map is complemented by statistical tables giving the total area of the land tenure categories for each State and Territory. This map is also available as free vector GIS data, ArcInfo Export, ArcView Shapefile and MapInfo mid/mif. Please direct any corrections or feedback on this map to mapfeedback@ga.gov.au. Product Specifications: Coverage: Australia Currency: Mid 1993 Coordinates: Geographical Datum: AGD66 Projection: Simple Conic on two standard parallels 18S and 36S Medium: Printed map (flat and folded); ## **Dataset History** Data was primarily sourced from Geoscience Australia's National Public and Aboriginal Lands data which contains data from State and Commonwealth Government gazettes. The Commonwealth Aboriginal and Torres Strait Islander Commission and State Government departments provided information on Aboriginal lands not gazetted. Other information was obtained from published maps and Geoscience Australia's National Topographic Mapping Series (NTMS).

##This dataset has been superseded. An updated version of this dataset is available from the ABARES website. This dataset is a national compilation of catchment scale land use data for Australia (CLUM), as at September 2017. It replaces the Catchment Scale Land Use of Australia - Update May 2016 released in June 2016. It is a seamless raster dataset that combines land use data for all state and territory jurisdictions, compiled at a resolution of 50 metres by 50 metres. It has been compiled from vector land use datasets collected as part of state and territory mapping programs through the Australian Collaborative Land Use and Management Program (ACLUMP). Catchment scale land use data was produced by combining land tenure and other types of land use information, fine-scale satellite data and information collected in the field. The date of mapping (2003 to 2017) and scale of mapping (1:5 000 to 1:250 000) vary, reflecting the source data, capture date and scale. This information is provided in a supporting polygon dataset. The following areas have been updated since the May 2016 version: Desert Channels and Mackay-Whitsundays natural resource management (NRM) regions in Queensland; the Adelaide and Mount Lofty Ranges NRM region in South Australia (extending into part of the Murray-Darling Basin NRM region); the state of New South Wales; the state of Victoria; the state of Tasmania; the state of Western Australia; and the Northern Territory. The capital city of Adelaide was also updated using 2016 mesh block information from the Australian Bureau of Statistics. This equates to over 585 million hectares or 76% of Australia, the largest update of catchment scale land use mapping to date. Users should update any references or links to previous CLUM datasets in their databases. Users should also note that it is not possible to calculate land use change statistics between annual CLUM national compilations as not all regions are updated each year; land use mapping methodologies, precision, accuracy and source data (in particular satellite imagery) have improved over the years; and the land use classification has changed over time. In particular, the major differences between this September 2017 version and the May 2016 version are: * The September 2017 version has been mapped to version 8 of the Australian Land Use and Management (ALUM) Classification (released in October 2016) * Improvements to the Western Australia mapping including improved mapping of native forests, conservation areas, topographic features, horticulture and intensive animal production * Changes to the mapping of native and modified pastures in New South Wales * Changes to the mapping of dairies in Tasmania so that only the dairy infrastructure is mapped as dairies and the dairy pastures are mapped as modified pastures. It is only possible to calculate change when earlier land use datasets have been revised and corrected to ensure that changes detected are real change and not an artefact of the mapping process. The Queensland Land Use Mapping Program (QLUMP) have done this on an NRM regions basis for Queensland and can be accessed at: * Data: Search the Queensland Spatial Catalogue (http://dds.information.qld.gov.au/dds/) for "Land Use Mapping" * Reports: https://www.qld.gov.au/environment/land/vegetation/mapping/qlump-reports. The CLUM data shows a single dominant land use for a given area, based on the primary management objective of the land manager (as identified by state and territory agencies). As a seamless spatial dataset for Australia, it can be used to identify, map and analyse high level land use categories (such as irrigated horticulture and dryland cropping) and more specific land use categories such as grapes, cotton, cereals, sugar and tree fruits. These categories can be extracted or combined with other spatial datasets to provide new insights and analysis concerning land use in Australia.
