The Sydney Morning Heald reports
The government cited the Foreign Incursions and Recruitment Act to warn that Australians could break the law if they went to fight in a foreign conflict, leaving them exposed to sanctions if they ever came home.
But the Challis Chair of International Law at the University of Sydney, Ben Saul, said fighting for the Ukraine government would not be a crime under the recruitment offences and that this suggested the way would be clear for Ukrainian Australians with dual nationality.
Professor Saul cautioned, however, that some activity could technically constitute terrorist offences, raising the prospect of prosecution.
The debate came after Ukraine Foreign Minister Dmytro Kuleba called for volunteers to help his country, floating an idea that could parallel the international volunteers who joined the Spanish Civil War in the 1930s.
