This chart shows the growth of Australia’s international science collaborations (measured by the number of co-authored publications) with various countries and regions from 2005 to 2024.

This is an important first step. Association with Horizon Europe would scale & diversify Australia international scientific collaborations

We’ve long advocated for Association to Horizon Europe, recognising it would mitigate geopolitical risks & deliver economic & scientific benefits to Australia.

PhD visa applicants trapped in ‘indefinite waiting period’ ‘Endless stress’ confronts Iranian doctoral candidates who worked for a year just to cover the application fee

Meanwhile, Australia still leaves in limbo many incoming students (holding PhD offers and funding!) for months on end, esp. from Iran. Waiting a year, two, with no updates — unnecessary and cruel.
