South Australia's demographic landscape is undergoing a profound transformation, and businesses that adapt to these shifts will thrive in the coming decade. The state's aging population, while presenting challenges, also opens doors for new markets and industries. Here's how South Australia can leverage these trends to its advantage.
The Aging Advantage
An older South Australia doesn't have to mean a less dynamic one. Demographer Simon Kuestenmacher argues that the state's aging population will force it to become more dynamic. By 2041, the 65-to-79-year-old population is projected to grow by 24%, and those aged 80 and over will more than double. This demographic shift creates a growing market for health, aged care, housing, leisure, financial services, and products that help people maintain independence.
However, it also presents a workforce challenge. With more than one in five residents aged over 65, industries like defense, construction, health, care, renewable energy, and advanced manufacturing are competing for workers. Kuestenmacher emphasizes that AI cannot replace the experience of skilled workers like nurses, electricians, engineers, and aged-care workers. Therefore, productivity, enabled by technology, becomes a crucial competitive advantage.
The Role of Migration
South Australia's population growth is increasingly reliant on overseas migration. In the year to December 2025, the state added 19,700 people, with net overseas migration contributing 18,500. This trend highlights the importance of attracting skilled migrants for employers, as competition for the same skills intensifies across defense, technology, energy, construction, and healthcare sectors.
Kuestenmacher suggests that businesses need to focus on three key areas: widening the workforce, retaining existing employees, and amplifying their productivity. This involves recruiting internationally and interstate, building stronger pathways through educational institutions, supporting disadvantaged groups, and creating opportunities for older workers to remain in the workforce.
The Millennial Market
Millennials, traditionally seen as young consumers, are now entering their 30s and 40s, a stage marked by career acceleration, family formation, and increased household spending. This shift in their life stage means they are no longer just a youth market. Their needs are shaped by mortgages, children, careers, and competing demands on their time and money.
Understanding the differences between generations and within them is crucial for businesses. Kuestenmacher warns against marketing purely by age, as life stage, health, housing tenure, and wealth are more indicative of consumer behavior. The key is to recognize that millennials, like other generations, have unique needs and preferences that businesses must address.
Emerging Industries and Workforce Opportunities
South Australia's emerging industries, particularly defense, renewable energy, space, and digital technology, offer significant opportunities to reshape the state's workforce profile. Defense alone is expected to add over 10,000 jobs by 2040, covering various roles like engineering, advanced manufacturing, cyber, robotics, trades, and technical positions.
These industries can disrupt the pattern of ambitious young South Australians leaving for Melbourne or Sydney. By turning these sectors into attractive career pathways, the state can retain more graduates, attract skilled workers from interstate, and bring in international talent. This could transform South Australia's demographic challenge into a competitive advantage.
Looking Ahead to 2035
By 2035, South Australia's economic identity is expected to have changed significantly. Kuestenmacher predicts that the state could become more technologically advanced, internationally connected, and economically important to Australia. The defining feature of the next decade will be the intersection of these trends.
An aging population creates new markets but reduces the available workforce, leading to increased automation and innovation. Skills shortages encourage migration, and defense, renewable energy, and advanced manufacturing attract investment and create new career pathways. The challenge for South Australian businesses is not to predict the future but to prepare for the forces already reshaping the state.
In conclusion, South Australia's demographic shifts present both challenges and opportunities. By understanding the changing demographics, attracting skilled workers, and embracing emerging industries, businesses can position themselves to thrive in the state's evolving economic landscape.
