The majority voted in favour of a motion introduced by South Australian Senator Sarah Hanson-Young (Greens), which means it passed. Motions like these don't make any legal changes on their own but are politically influential because they represent the will of the Senate.
That the Senate:
(a) affirms its commitment to a complete moratorium on nuclear energy, as expressed in the Australian Radiation Protection and Nuclear Safety Act 1998 and the Environment Protection and Biodiversity Conservation Act 1999;
(b) notes the devastating and lasting impacts of the nuclear disasters in Fukushima, Chernobyl and Three Mile Island; and
(c) call on all Ministers to commit to Australia being a nuclear-free zone.
