This dataset is the definitive set of annually released statistical area 1 (SA1) boundaries at 1 January 2019, clipped to the coastline. This clipped version has been created for map creation/cartographic purposes and may not fully represent the official full extent boundaries. SA1 is an output geography that allows the release of more detailed information about population characteristics than is available at the meshblock level. SA1s are defined at meshblock level.
Digital boundary data became freely available on 1 July 2007. This generalised version has been simplified for rapid drawing and is designed for thematic or web mapping purposes.
