South Australia's Property Market Growth: How the Defence Industry and Technology Sector are Driving Property Prices

South Australia is experiencing an extraordinary transformation that's reshaping its property landscape. As we step into 2026, two powerful economic forces are converging to create unprecedented opportunities in South Australia's property market growth story—a booming defence industry and an explosive technology sector expansion that few saw coming just five years ago.
The Defence Industry Boom Driving Property Demand
South Australia has cemented its reputation as Australia's 'Defence State', and the numbers tell a compelling story. According to the Australian Bureau of Statistics, South Australia's defence industry contributed $1.9 billion to the national economy in 2023-24, representing a remarkable 30 per cent increase and adding $425 million in just one year. More impressively, the sector's workforce expanded by 15 per cent, creating an additional 1,300 highly skilled jobs.
The Osborne shipyards on the Lefevre Peninsula represent the epicentre of this transformation. Under the AUKUS agreement, Australia will begin building nuclear-powered submarines in Adelaide by the end of this decade. At its peak, up to 4,000 workers will be employed to design and build infrastructure for the submarine construction yard, with a further 4,000-5,500 direct jobs expected when the program reaches full capacity in 20-30 years.
South Australia's property market growth implications are profound. The current South Australian defence industry workforce of around 5,500 is forecast to grow to more than 11,000 by the 2040s, including 8,500 direct jobs and 2,900 in supply chains. This isn't just about numbers—it's about highly paid professionals seeking quality housing near their workplaces.
Paul Virdi, Director of Alpha Real Property Group, observes: "We're witnessing a fundamental shift in Adelaide's property dynamics. The defence industry expansion isn't a short-term boom—it's a 30-year commitment that's bringing financial security and long-term planning to the market. Suburbs within a 20-kilometre radius of Osborne are experiencing demand from buyers who understand they're investing in one of Australia's most strategically important employment hubs. This isn't speculation; it's calculated investment in infrastructure-backed growth."
Technology Sector: The Hidden Driver of Property Appreciation
While defence grabs headlines, South Australia's technology sector transformation is equally dramatic. The 2025 ACS Australia's Digital Pulse report reveals that South Australia's technology workforce has contributed $5 billion to the state economy and now employs more than 40,800 individuals. The projection? By 2035, the number of technology professionals in South Australia is expected to reach approximately 89,400, representing an increase of 49,000 workers.
This technology surge isn't abstract - it's attracting global players. Major tech companies, including Accenture, Google Cloud, Microsoft Azure Space, and Deloitte, have expanded into South Australia, with Accenture alone expected to create up to 2,000 new jobs over five years, whilst Cognizant is creating 1,600 jobs in artificial intelligence, machine learning, and cloud computing.
South Australia's, property market growth connection becomes clear when examining salary levels. The South Australian space sector has seen remarkable growth, with employment increasing from 100 to 1,600 jobs since 2017, with a median salary of $98,000. These high-earning tech professionals are entering a property market that remains remarkably affordable compared to Sydney and Melbourne.
The Property Market Response
Adelaide's property market has responded decisively to these economic tailwinds. Home values in Adelaide grew 2.1 per cent in the final quarter of 2024, outpacing Brisbane/Gold Coast and Perth, with the South Australian capital's home values increasing 13.1 per cent over the entire year.
The median dwelling value dynamics reveal South Australia's property market growth trajectory. In July 2025, Adelaide's dwelling values increased by 0.7%, bringing annual growth to 7.0%, with the median dwelling value reaching $723,655. Strategic suburbs near employment hubs are experiencing particularly strong growth, with top-performing suburbs including Gawler–Two Wells (9.8%), Playford (9.4%), and Adelaide Hills (9.2%).
The rental market tells an equally compelling story. Adelaide's rental market shows a 4.2 per cent increase from August 2024 to August 2025, with the vacancy rate remaining at a tight 0.8 per cent, whilst the rental yield currently stands at 3.7 per cent.
Population Growth Fueling Demand
Supporting the South Australia property market growth is steady population expansion. At 30 June 2024, 1.469 million people were living in Greater Adelaide, with the population increasing by 22,125 persons at a growth rate of 1.53%. This growth, combined with limited housing supply, creates sustained upward pressure on property values.
The 2026 Outlook - Conclusion of South Australia's Property Market Growth Story
As we enter 2026, the convergence of defence industry expansion, technology sector growth, and constrained housing supply positions South Australia's property market uniquely. Unlike speculative boom-and-bust cycles, this growth is underpinned by genuine employment opportunities in high-paying sectors with long-term government and private sector commitments.
For investors and homeowners, the message is clear: South Australia's two economic surprises—defence and technology—aren't temporary phenomena. They represent a structural shift that's rewriting the state's economic DNA and, with it, its property market trajectory. The smart money isn't asking whether to invest in Adelaide; it's asking which suburbs will benefit most from Australia's fastest-growing high-tech defence and innovation ecosystem.
