Australia’s two most populous states, New South Wales and Victoria, contributed the most to the country's output of high-quality natural science in 2015. Australia placed 12th in the global index ranking last year.
State capital, Perth, produced the vast majority of Western Australia's output in the index last year. The city had a WFC of 80.7 and an article count of 799.
The state of Victoria produced the most high-quality natural science research in 2015, followed by New South Wales and Queensland.
Five New Zealand cities drove the country's output of high-quality natural science in 2015. The country placed 30th in the global index ranking last year.
Chemistry and physical sciences research made up two thirds of Wellington’s contribution to the index in 2015.
Auckland’s main output in the index was chemistry in 2015.
Earth and environmental sciences made up the bulk of Christchurch’s WFC.
Bubbles are sized by 2015 weighted fractional count (WFC)
Article count (AC): A country or institution's article count is the number of articles in the index that have at least one author from that country or institution.
Weighted fractional count (WFC): the weighted fractional count measures the contribution of institutions to articles in the index.

Output over time
Australia's contribution to the index, measured by WFC, has increased, while New Zealand's output has declined between 2012 and 2015. The total number of articles included in the index increased for both countries.
Australia's greatest contribution to the index in 2015 was in life sciences, while New Zealand excelled in Earth and environmental sciences.
* As subjects may overlap, the sum of the subject area WFCs may therefore exceed the country's overall WFC.
Box 1: NATURE INDEX
The Nature Index database tracks the affiliations of high-quality natural science articles, and charts publication productivity for institutions and countries. Article count (AC) includes the total number of affiliated articles. Weighted fractional count (WFC) accounts for the relative contribution of each author to an article, and adjusts for the abundance of astronomy and astrophysics papers. More details here.
