Nearly half of the jobs in Australia are at high risk of "digital disruption" in the next 20 years, and our education system is not equipping students with the skills needed to adapt, a new report warns.

PricewaterhouseCoopers chief executive Luke Sayers is calling for a national summit on the issue, saying universities need to start producing far more people literate in science, technology, engineering and mathematics subjects (STEM) to help the workforce adapt to a rapidly changing global economy.

PwC's report, The STEM Imperative: Future Proofing Australia's Workforce, warns many of the jobs people work in today "simply won't exist in the next decade, either entirely, or at the same number".

The report's modelling shows the top three occupations in Australia most at risk of being automated in the next two decades are accountants, cashiers and administration workers, affecting more than 600, 000 workers. The least likely are doctors, nurses and teachers.
