Australia does not possess weapons of mass destruction, although it has participated in extensive research into nuclear, biological and chemical weapons in the past.
Australia chairs the Australia Group, an informal grouping of countries that seek to minimise the risk of assisting chemical and biological weapon proliferation. All states participating in the Australia Group are parties to the Chemical Weapons Convention and the Biological Weapons Convention, and strongly support efforts under those Conventions to rid the world of chemical and biological weapons.[1] As with chemical and biological weapons, Australia does not possess nuclear weapons and is not seeking to develop them.
