Australia has one of the lowest population densities in the world, with a population of 23 million and a land area of over 7.6 million square kilometres. This results in a density of around three people per square kilometre. The country has a low natural increase due to low birth and death rates, and its population is ageing. To solve the problem of underpopulation, Australia has focused on immigration, attracting a quarter of a million migrants each year. This has been crucial to the country's economic growth and development, underpinning demand across various sectors. However, a coherent whole-government population policy is needed to address the challenges of infrastructure, education, employment, healthcare, transport, housing, and the environment.

What You'll Learn
Encourage skilled migration
Australia has long been a destination for migrants, with its strong economy and low unemployment attracting well-educated and skilled workers from around the world. In 2019, Australia had the second-highest share of migrants in the OECD (after Luxembourg), with migrants making up 30% of its population. Migration has been a key driver of Australia's economic growth, underpinning demand for housing, education, healthcare, and other services.
To encourage skilled migration, the Australian government has implemented several policies. Firstly, despite reducing the overall migration ceiling by 15% in the 2019/2020 visa program, the government increased the number of permanent employer-sponsored skilled visa spaces by nearly 10%. This increase, from 35,528 to 39,000 visas, aimed to meet the high demand for skilled workers in certain sectors.
Secondly, the government introduced two new regional skilled visa categories to encourage foreign nationals to settle in regional areas. These include the Skilled Employer-Sponsored Regional (Provisional) Visa and the Skilled Work Regional (Provisional) Visa, offering a total of 23,000 spots. These visas allow foreign nationals in eligible occupations to be sponsored by employers or nominated by state governments to live and work in regional Australia.
Thirdly, initiatives have been created to attract international students to regional areas. Recognizing the economic benefits of skilled migration, Australia expects to continue favoring highly skilled foreign nationals in its immigration policies. By attracting skilled migrants and channeling them to regional areas, Australia aims to address underpopulation and promote sustainable growth while maintaining the quality of life for its citizens.
Australia's approach to skilled migration is an important aspect of its population policy. By attracting skilled workers, Australia can boost its economy, fill labor market gaps, and address the challenges posed by an aging population. However, it is crucial to balance migration with adequate investment in infrastructure, transport, and other public services to ensure that population growth does not outpace the country's capacity to accommodate new arrivals.

Develop semi-desert areas
Australia's semi-desert areas, covering over 70% of the continent's landmass, present unique challenges and opportunities for development. These regions, including the Great Victoria Desert, the Simpson Desert, and the Tanami Desert, are characterised by low rainfall, high temperatures, and sparse vegetation. However, they also possess a diverse array of life, with resilient plant species like spinifex grass and iconic animals such as kangaroos, emus, and dingoes.
To develop these semi-desert areas sustainably, several approaches can be taken:
- Desert Greening Initiatives: Australia has already undertaken significant efforts in desert restoration, known as "greening" projects. These initiatives aim to restore arid and semi-arid regions, improve soil moisture retention, and support plant growth. This includes using innovative techniques such as hydrogel-based soil conditioners and biodegradable mulches. Additionally, integrating traditional ecological knowledge with modern conservation techniques, as demonstrated by the Waanyi-Garawa Rangers in the Northern Territory, has successfully restored degraded land and protected endangered species.
- Planting Native Vegetation: Selecting drought-tolerant native plant species, such as acacias, eucalypts, and saltbushes, is crucial for successful greening projects. Increasing vegetation cover through planting trees, shrubs, and grasses helps reduce soil erosion, enhances biodiversity, and provides habitat for wildlife.
- Technological Integration: Technology plays a vital role in enhancing the effectiveness of desert restoration. Geographic Information Systems (GIS) facilitate data analysis and decision-making, helping prioritise restoration areas. Remote sensing technologies, including satellite imagery and drones, enable monitoring of ecosystem health and identification of degradation.
- Addressing Human Activities: Human activities such as overgrazing, land clearing, and resource extraction have contributed to soil erosion, biodiversity loss, and habitat fragmentation in semi-desert ecosystems. Implementing sustainable land management practices and regulating these activities are essential to protect and restore these fragile environments.
- Infrastructure Development: Developing infrastructure in semi-desert areas can support population growth and distribution. This includes improving transportation networks, such as the proposed Outback Highway, and investing in housing and essential services. Additionally, focusing on regions with existing infrastructure, like Melbourne, Sydney, and Brisbane, can help manage population growth sustainably.
- Attracting Migration: Australia's ability to attract migrants has been a significant contributor to its economic growth. By creating incentives and opportunities, Australia can continue to attract skilled migrants, supporting population growth in semi-desert areas.
By implementing these strategies, Australia can sustainably develop its semi-desert regions, addressing underpopulation and promoting economic growth while preserving the delicate ecological balance of these unique environments.

Invest in infrastructure
Australia has one of the lowest population densities in the world. With a population of 23 million and a land area of over 7.6 million km², its density is around 3 people per km². This is very low compared to Monaco, the most densely populated area in the world with 26,150 people per km².
Despite this, Australia has a problem with underpopulation. The country's population is ageing, and there is a lack of coherent national policy to manage it. The focus needs to be on maintaining quality of life through sustainable growth. One way to do this is by investing in infrastructure.
Australia has a problem with inadequate infrastructure in its major cities, particularly Melbourne, Sydney, and Brisbane, the main destinations for immigrants. To solve this problem, the government needs to invest in infrastructure such as public transport, housing, schools, and hospitals.
New South Wales, the country's most populous state, plans to invest A$60 billion in infrastructure in the next four years to meet growing demand. This includes investing in public transport to improve mobility and accessibility within the state. The government also needs to invest in housing, as the inflow of migrants has increased the demand for housing.
Additionally, the government should invest in schools and hospitals to accommodate the growing population. This includes building new schools and hospitals, as well as improving the existing ones. The government should also consider investing in renewable energy infrastructure to ensure a sustainable future for the country.
Investing in infrastructure is crucial to support the growing population and maintain a high quality of life in Australia. By investing in public transport, housing, schools, and hospitals, the government can ensure that the country can accommodate more people without compromising the well-being of its citizens.

Address water shortages
Water scarcity is a pressing issue in Australia, which has long had a precarious relationship with water due to its low and unevenly distributed rainfall. The country's limited and unpredictable rainfall is being exacerbated by climate change, with the continent one degree warmer than a hundred years ago and receiving significantly less rain.
To address water shortages, Australia has taken several measures and adopted new technologies. Here are some ways Australia is tackling water scarcity:
- Investing in desalination plants: All mainland states are investing in large desalination plants, which can produce up to 674 gigalitres of additional freshwater. However, this method is costly and controversial due to its high energy consumption.
- Treated wastewater and Indirect Potable Reuse: Some states, like Western Australia, are actively replenishing their aquifers by pumping treated wastewater into shallow aquifers for natural filtration and storage. This process, known as Indirect Potable Reuse, has the potential to bring cities and homes closer to self-sufficiency.
- Water efficiency and conservation: Many products in Australia are now rated and labelled for water efficiency, encouraging the adoption of water-saving features in homes. More than a quarter of Australian households also collect and store rainwater for domestic use, contributing significantly to residential water supplies.
- Water-prudent energy sources: Policymakers are encouraged to prioritize water-prudent energy sources, such as solar and wind power, to avoid power shutdowns caused by water shortages.
- Urban water resilience action plans: Cities should develop strategies to enhance their resilience to water scarcity, learning from successful pilots in African cities.
- Efficient agricultural practices: Farmers can implement more efficient water measures, such as adopting water-efficient crops or using methods like sprinkler or drip irrigation instead of flooding fields.
By implementing these strategies and continuing to innovate, Australia is working towards securing its water future and addressing the challenges posed by water shortages.

Support ageing population
Australia's ageing population will have a significant impact on the country's future, reshaping society, the economy, and the community. As such, supporting the ageing population is a crucial aspect of addressing underpopulation in Australia.
Firstly, Australia's universal health system and subsidised aged care system will need to be adequately funded to cater to the rising demand for healthcare services. This includes addressing the current shortfall of residential aged care places in rural and remote areas, as well as the projected need for additional residential care places and home care packages in these regions by 2032. The country is already facing a shortage of care workers, and it is projected that by 2050, Australia will require an additional 285,800 workers in aged care, disability, and mental health support services. To address this, a multi-pronged approach is necessary, including workforce recruitment and retention initiatives, especially in non-metropolitan areas, and the integration of technology, such as telehealth, to enhance the delivery of skilled aged care.
Secondly, the ageing population will have economic implications. As the number of older Australians increases, spending pressures are expected to rise, particularly in the areas of health, age pensions, and aged care. This will result in increased government spending, impacting the overall share of the government in the economy. To mitigate these fiscal challenges, the government should foster the development of financial instruments that assist in managing retirement incomes, such as annuities, long-term indexed bonds, and housing equity withdrawal products. Additionally, the government should focus on creating opportunities from the challenges of population ageing, investing in Australians (both locals and migrants) to improve their quality of life.
Thirdly, the ageing population will lead to a shift in community dynamics and infrastructure needs. There may be a need for more health centres and senior-friendly facilities, such as seniors' gyms, rather than schools and playgrounds. This shift will also impact national and household finances, with potential discussions around intergenerational fairness in taxation arising.
Finally, to effectively support the ageing population, a coherent whole-of-government population policy is required. This policy should address various domains, including education, training, healthcare, housing, employment, and the environment. It should set a blueprint for the future and map out milestones to ensure progress toward these aims. While there are challenges ahead, Australia has made progress in addressing the demographic fiscal challenge through improved fiscal positions, better participation, and the introduction of policy measures.
