11th Feb 2020, 4:15 PM – Senate Motions - Nuclear Energy - Australia as a nuclear-free zone

Show detail

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.

Motion text

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.

No No Not passed by a small majority

17th Oct 2018, 3:21 PM – Senate Motions - Nuclear Energy - Lift ban

Show detail

The majority voted against a motion introduced by Senator Cory Bernardi (SA), which means it failed.

Motion text

That the Senate—

(a) notes that a recent Intergovernmental Panel on Climate Change report on limiting global temperature increase by 1 degrees by 2050:

(i) stated that 'nuclear increases its share in most 1 degree pathways by 2050',

(ii) indicated in some projections that nuclear energy generation could expand by as much as 200 exajoules by 2100 – the equivalent of double the United States of America's annual consumption,

(iii) estimated nuclear energy generation would increase by 2 times by 2050 in 85 mitigation scenarios, and

(iv) the median uptake of primary energy supply via nuclear energy across the 85 mitigation scenarios between 2020 and 2050 was 7 per cent, more than renewable energy (6 per cent) and biomass (5 per cent);

(b) further notes that investigation of nuclear energy generation in Australia has been the subject of a legislative ban imposed at the behest of The Greens for almost 20 years; and

(c) calls upon the Federal Government to take steps to allow the consideration of nuclear energy generation in Australia's energy mix.

No Yes Not passed by a large majority

How "voted a mixture of for and against" is worked out

The MP's votes count towards a weighted average where the most important votes get 50 points, less important votes get 10 points, and less important votes for which the MP was absent get 2 points. In important votes the MP gets awarded the full 50 points for voting the same as the policy, 0 points for voting against the policy, and 25 points for not voting. In less important votes, the MP gets 10 points for voting with the policy, 0 points for voting against, and 1 (out of 2) if absent.

Then, the number gets converted to a simple english language phrase based on the range of values it's within.

No of votes Points Out of
Most important votes (50 points)      
MP voted with policy 0 0 0
MP voted against policy 0 0 0
MP absent 0 0 0
Less important votes (10 points)      
MP voted with policy 1 10 10
MP voted against policy 1 0 10
Less important absentees (2 points)      
MP absent* 0 0 0
Total: 10 20

*Pressure of other work means MPs or Senators are not always available to vote – it does not always indicate they have abstained. Therefore, being absent on a less important vote makes a disproportionatly small difference.

Agreement score = MP's points / total points = 10 / 20 = 50%.
