Hi Jo
the new Australian Government Style Manual (Style Manual) supersedes the Content Guide.
You can see a summary of the differences between the Style Manual and the Content Guide (and the sixth edition of the Style Manual) on the Style Manual Changelog.
We are in the process of setting up a banner and some redirects from the Content Guide to let users know about the change.
You can find out more about the Style Manual by reading the About and Getting started pages, including that it replaces the Content Guide.
We will be switching off the Content Guide on 23 October 2020. The information will still be available through Trove’s snapshots of the Content Guide.
If you want to stay in touch with the Style Manual you can subscribe to our monthly newsletter. You can also tell us what you think about the Style Manual using the feedback form at the bottom of every page.
Cheers
Susan Baird
Style Manual Team
