**Please note this dataset is an archived version of the Geocoded National Address File (G-NAF). For the latest version of the G-NAF please go to this url: https://data.gov.au/dataset/ds-dga-19432f89-dc3a-4ef3-b943-5326ef1dbecc/details?q=gnaf**\r\n\r\n-------------------------------------\r\n\r\nGeoscape G-NAF is Australia’s authoritative, geocoded address file. It is built and maintained by [Geoscape Australia](https://geoscape.com.au/) using authoritative government data. Further information about contributors to G-NAF is available [here](https://geoscape.com.au/legal/data-copyright-and-disclaimer/).\r\n\r\nG-NAF is one of the most ubiquitous and powerful spatial datasets. It contains more than 15 million Australian physical address records. The records include geocodes, which are latitude and longitude map coordinates. G-NAF does not contain personal information or details relating to individuals.\r\n\r\nUpdated versions of G-NAF are published on a quarterly basis.\r\n\r\nUsers have the option to download datasets with feature coordinates referencing either GDA94 or GDA2020 datums.\r\n\r\n**Changes in the August 2024 release**\r\n\r\n* Nationally, the August 2024 update of G-NAF shows an increase of 44,191 addresses overall (+0.28%). The total number of addresses in G-NAF now stands at 15,698,769 of which 14,864,193 or 94.68% are principal.\r\n\r\n* In the August 2024 release, 660 addresses in New South Wales, 440 addresses in Queensland and 80 addresses in Victoria have been retired. In both cases, the addresses are considered not in use by the community.\r\n\r\n* The spatial upgrade works being undertaken in Victoria are continuing and as a result of the cadastral shifts generated, the geocodes of many addresses related to those parcels have moved. In the Aug 2024 update, approximately 25,000 address geocodes have been moved. These movements generally range from 1 metre to 40 metres with the majority being around 2 to 7 metres.\r\n\r\n* There were significant mismatches in the links between G-NAF and Geoscape Cadastre and Geoscape Property in the ACT. In the August 2024 release of G-NAF, there have been some 13,000 updates to the LEGAL_PARCEL_ID attribute and 75,000 updates to the GNAF_PROPERTY_PID attribute in the ACT.\r\n\r\n* Geoscape has moved product descriptions, guides and reports online to https://docs.geoscape.com.au. From May 2024 release onwards, data packages will no longer include the ‘Documents’ folder.\r\n\r\nFurther information on G-NAF, including FAQs on the data, is available [here](https://geoscape.com.au/data/g-naf) or through Geoscape Australia’s network of [partners](https://geoscape.com.au/partners/). They provide a range of commercial products based on G-NAF, including software solutions, consultancy and support.\r\n\r\nNote: On 1 October 2020, PSMA Australia Limited began trading as Geoscape Australia.\r\n\r\n##License Information\r\n\r\n[Use of the G-NAF downloaded from data.gov.au is subject to the End User Licence Agreement (EULA)](https://data.gov.au/dataset/ds-dga-19432f89-dc3a-4ef3-b943-5326ef1dbecc/distribution/dist-dga-09f74802-08b1-4214-a6ea-3591b2753d30/details?q=)\r\n\r\nThe EULA terms are based on the Creative Commons Attribution 4.0 International license (CC BY 4.0).

The dataset is primarily designed for application developers and large-scale spatial integration. Users are advised to read the [technical documentation](https://geoscape.com.au/documentation/), including product change notices and the individual product descriptions before downloading and using the product. [A quick reference guide on unpacking the G-NAF is also available.](https://geoscape.com.au/wp-content/uploads/2020/09/Unpacking-GNAF-.pdf)\r\n

* 全国范围内，2024年8月版G-NAF共新增44191条地址记录（增幅0.28%），当前G-NAF的地址总数达15698769条，其中14864193条为主要地址，占比94.68%。

* 本次2024年8月版中，新南威尔士州、昆士兰州和维多利亚州分别有660条、440条和80条地址记录被退役，此类地址均被认定为社区不再使用的地址。

* 维多利亚州正在推进的空间升级工作仍在进行中，由于地籍权属变更产生的地块位移，相关的大量地址的地理编码均发生了调整。在2024年8月版更新中，约25000条地址的地理编码被调整，调整幅度普遍在1米至40米之间，其中多数调整幅度约为2至7米。

* 在首都领地（ACT），G-NAF与Geoscape地籍系统、Geoscape房产系统之间的关联存在大量不匹配问题。在2024年8月版G-NAF中，首都领地的LEGAL_PARCEL_ID属性共完成约13000条更新，GNAF_PROPERTY_PID属性共完成约75000条更新。
