This article is confusing overall - it talks about STEM in the headline, then cites a general chart by Grattan Institute (a policy think tank) similar to another recent piece by Grattan's Andrew Norton (quoted in the SMH piece): https://grattan.edu.au/news/graduate-employment-is-up-but-fi... .
Not familiar with Australia, but there's also recent articles of it being in per-capita recession. (see https://www.smh.com.au/business/the-economy/australia-falls-... )
