Attribution
Commonwealth data on this site is used under the licence each publisher states, and the figures are reformatted, rounded and joined for display. The standing attribution is:
© Commonwealth of Australia. Data from Jobs and Skills Australia, used under CC BY 4.0 and reformatted for presentation.
Vintages differ across a single role page. Headcount and task statements are 2021 Census, pay is May 2025, growth is February 2026 and demand is July 2026, so every figure carries its own date next to it rather than borrowing the page’s.
Using our data
Our AI redundancy tracker and the quarterly report we build from its named redundancy rounds are released under CC BY 4.0. You are free to share and adapt it, including commercially, as long as you attribute Changing Careers and link to the report. The Commonwealth datasets above are not ours to relicense, so use those under the licence each publisher gives.
What we publish as downloadable data, with the attribution line and a suggested citation for each, is on the Changing Careers open data page.
