Australians are concerned about environmental, economic and social impacts of ongoing population growth. The latest survey shows that 69% of Australians believe we do not need more people and 70% think we should not return to the high pre-COVID levels of net migration.

Sustainable Population Australia (SPA) is an environmental advocacy group which is translating these concerns into practical action to influence government and public opinion, and to end population growth in Australia and globally. Our patrons are leading scientists and respected community leaders: Emeritus Professor Ian Lowe, Dr Tim Flannery, Dr Katharine Betts, Dr Paul Collins and the Hon. Bob Carr.

But now big business – the ‘growth lobby’ – is arguing for a return to Big Australia after the borders open. They are pressuring the government to return to pre-COVID levels of population growth, and the government is planning net overseas migration of 235,000 a year. That would mean a return to the same ol’ same ol’ of congested cities, low per capita incomes growth and a deteriorating natural environment.

We urgently need to tell our politicians that we do not want a return to the Big Australia path. The current pandemic presents a critical opportunity to re-think and re-set Australia’s population future. SPA has prepared a detailed statement about this opportunity to rethink a Big Australia, which you can read here.

SPA is campaigning for a much more realistic and manageable net migration level of around 60,000 a year. The growth lobby wants the population to grow forever but SPA is campaigning for a maximum population of 30 million. These figures are round figures just to make the conversation easier; what matters is that whatever the figures are, the annual net migration figure should be as low as is feasible, and the population ceiling of 30 million should be understood as a maximum, to be reached as slowly as possible, and not as a stepping stone to ever more.

With your support, SPA can actively work to refute and resist the growth lobby arguments, and get Australia onto an ecologically sustainable pathway.
