The Centre for Population, part of federal Treasury, was established in 2019 to improve data collection on how Australia’s population is changing and the implications of these changes.

The Centre makes an annual statement of population including analysis of changes over the past year. The 2022 statement has recently been released. This report also covers projections of future population levels out to 2033 as well as analysis of the impact of COVID on recent migration and mortality experience. It is good to see regular information in one location instead of previously having to delve into ABS and Department of Immigration website data.

This report brought out the usual hype in the media about the need for new migrants to stave off the ageing population burden and labour skill shortages. There is only limited discussion of the impact the growth will have on significant aspects of social and environmental wellbeing, such as cost of housing and biodiversity.

Projections for next 10 years

The baseline assumption of future net overseas migration (NOM) is 235,000 per annum based on the average over recent years prior to the COVID-19 slowdowns plus some adjustment for policies increasing permanent placements. Despite the COVID experience we are still trying to catch up on the demand for services and infrastructure that was generated by the escalation of growth that was started by the Howard government in 2006 and has been perpetuated by subsequent Labor and Coalition governments ever since. Prior to 2006 NOM was half that level or less.

Our current population is 26.1 million (as at September 2022). The projection in the Population Statement 2022 is that we will reach 30 million by mid-2033. However, the level of migration has been ramped up since the Labor government came to power as a backlog of applications is being processed and international students are flooding back. It is estimated that the NOM for the next two years will be 650,000 so that growth including natural increase (births less deaths) will approach 950,000. No wonder there is a housing crisis! The slowdown during the COVID-19 shutdown is becoming irrelevant.

Intergenerational report — projections to 2060

The 2021 Intergenerational Report provides longer term projections of the outlook for the economy and budget.

This report used the same assumption for NOM of 235,000 pa for the whole 40 years of their projections. The total population in 40 years’ time is projected to be an eye-watering 39 million. That is a 13 million more people, a 50% increase! The growth over the past 40 years was 11 million. We can see the impact of that number. To use the hackneyed catch phrase, it is unsustainable. Liveability of our cities has declined. The State of the Environment Report 2021 showed significant declines in biodiversity. Surveys have highlighted that citizens do not want this high rate of growth to continue.

The governments at state and federal level express plans to stop species extinctions, reduce carbon emissions and improve liveability but they carry on, regardless of popular opinion, doing nothing to stop the forces that go against these policies; vegetation clearing, bigger houses, more roads.

Apparently, there is no contemplation that our growth will ever slow down. The concept of longer term planning whereby the growth can be reduced over time is anathema to the politicians and business even though it would be welcomed by voters. We have to accept the reality of adapting by increasing skill levels, retraining the existing workforce and increasing workforce participation into retirement age. The easy option is still being taken by importing skills from countries that need them more. The hard decisions are being left to future generations.

Alternative viewpoints

Sustainable Population Australia, an environmental advocacy organisation, has recently published some discussion papers with academic analysis calling into question the status quo.

The housing crisis is a population growth crisis

Some of the key points made are:

• The connection between population growth – driven by high immigration – and high housing cost inflation is often ignored or denied in political circles but is accepted as an undeniable fact by almost everyone knowledgeable about the property industry.
• An accumulation of ill-advised policy measures (e.g. negative gearing, reduction in capital gains tax and first home buyer grants) have combined with accelerated population growth to create a perfect housing storm.
• A lower net migration level is needed to slow growth and stabilise population size. Even an optimally regulated market will not prevent housing inflation in the face of endless population growth.
• Lower, well-targeted immigration will not cause intractable skills shortages or unmanageable population ageing, but will reduce housing stress and inequality, and improve environmental amenity.

How many Australians? The need for Earth-centric ethics

This discussion paper has been written by Dr Paul Collins, an historian, broadcaster and the author of 17 books on Catholicism, the papacy, environmental ethics and population issues.

The paper addresses the competing demands of human beings seeking a better life with the rights of our natural systems to prevail against the demands of human activities.

Despite its physical size, Australia is limited in biophysical and geophysical terms. All our State of Environment reports have found the demands of the current population have been degrading natural systems irreversibly. We are not living sustainably with the numbers we have at current standards of living.

Millions want to come and share the riches we enjoy. Do we have a moral duty to let them come and allow them a better life? Or should we protect the ecosystems in our care?

He calls for a totally new moral principle to guide and govern our ethical behaviour as a species. He argues that we must shift our ethics away from anthropocentrism and economism which pays no heed to our dependence on the natural world. Instead, moral decision-making must give priority to the Earth, biodiversity, climate stability and the integrity of natural systems.
