Sustainable Population Australia


Sustainable Population Australia (SPA) was formed in 1988 by people who felt that the issue of population numbers was overlooked, or regarded as too contentious, by many of those striving to preserve Australia's ecological heritage.

It has held public meetings and conferences in many parts of Australia. SPA branches around the country promote SPA's ideas, study local problems, lobby politicians and recruit new members.

Some branches hold regular meetings but the main link between members is the Newsletter, produced six times a year. This provides members with information and expert opinion to rebut the many myths about sustainability and population that one hears in conversation or sees in the press.

Formerly known as Australians for an Ecologically Sustainable Population, SPA is an ecological group dedicated to preserving species' habitats globally and in Australia from the degradation caused by human population growth. We work on many fronts to encourage informed public debate about how Australia and the world can achieve an ecologically sustainable population.

Aims & Objectives


Sustainable Population Australia (SPA) was established in Canberra in 1988 under the name Australians for an Ecologically Sustainable Population (AESP). The people who founded AESP felt that, since the major environmental groups were failing to address the issue of population numbers, a separate organisation was needed.

While SPA is primarily an environmental organisation, it also addresses the social and economic implications of population growth.

SPA has grown into a national organisation with members in all states and territories and branches in eight major cities.

Until her death in the year 2000, the poet Judith Wright was AESP's sole Patron. Now four eminent Australians are Patrons of SPA: Professors Ian Lowe and Tim Flannery and Drs Mary White and Paul Collins.


  • To contribute to public awareness of the limits of Australian population growth from ecological, social and economic viewpoints.
  • To promote awareness that the survival of an ecologically sustainable population depends on its renewable resource base.
  • To help promote policies that will initially lead to stabilisation of Australia’s population by encouraging near replacement fertility rates and low immigration rates.
  • To promote urban and rural lifestyles and practices that are in harmony with the realities of the Australian environment, its resource base and its biodiversity.
  • To advocate low immigration rates while rejecting any selection based on race.
  • To help promote policies that will lead to the stabilisation, then reduction of global population.
