There are two ways that all data for all regions can be accessed:
1 There are 8 data cubes - in zipped CSV format - that can be opened in a variety of packages, including Excel. These files are found in the Downloads tab.
2 All of the data can also be found in ABS.stat, which provides a flexible way to access data. In ABS.stat, data, regions and time periods can be selected to produce customised tables.
