In December 2015, Australia’s Federal Parliament amended the Citizenship Act 2007 (Cth) (“Citizenship Act”) to add avenues by which dual citizens could lose their Australian citizenship for terror-related conduct. Much of the commentary on the amendments has focused on the justifications behind the legislation, and the implications for Australia’s compliance with international human rights. Less commentary has focused on how the new provisions interact with, and likely contravene, Australia’s international security obligations.
