The nationalisation of K-12 education in Australia has the potential to have a Jupiter Effect (prediction that an alignment of the planets would create a number of catastrophes) on school libraries and the profession. Government-driven initiatives and projects herald an education 'two-speed economy' for teacher librarians - boom or bust. The report, School libraries and teacher librarians in 21st century Australia, and data from 386 submissions and 13 public hearings provide sufficient evidence that school libraries and teacher librarianship are at a tipping point. This address will present a view on the impact of the nationalisation of K-12 education and explore strategic directions for the profession and school libraries. What will be the future if you do not take charge of your own siesmic shift?
