The Australian National University has been ranked Australia's most "international" university, according to the Times Higher Education World University Rankings.
The latest ranking table assesses the top 200 most "outward-looking institutions" in the world, as distinct from the Times' more general league table of top 800 global institutions – which saw the ANU come in at 52nd place last year after the University of Melbourne in 33rd place.
"International" universities are judged on their proportion of international staff, proportion of international students and proportion of research papers published with at least one co-author from another country.
Qatar University topped the list, followed by the University of Luxembourgin second place and the University of Hong Kong in third.
The United Kingdom rated the best country, with 66 international institutions in the top 200. The United States, meanwhile, only managed to get nine in the top 200, with the Massachusetts Institute of Technology debuting in 90th place.
Switzerland, meanwhile, dominated the top ten, with its Ecole Polytechnique Federale de Lausanne coming in fourth place, the University of Geneva coming in fifth, the Swiss Federal Institute of Technology Zurich coming in seventh and the University of St Gallen coming in eighth.
After the ANU in 25th place, the next best Australian performer was Curtin University in 26th place, the University of Western Australia in 31st place, the University of Technology Sydney in 46th place and Macquarie University in 49th.
New vice chancellor and Nobel Laureate Professor Brian Schmidt said "the ranking reflects the unique role ANU plays in linking Australia to the world".
"Our staff and students draw on the best research from across the globe, and that is what continues to attract the best people to join us."
Professor Schmidt said the ranking showed ANU was fulfilling its "founding mission to ensure Australia takes its seat at the table of global research and learning".
"ANU is doing its part to bring Canberra to the world and the world to Canberra," he said.
