Australia’s real estate market is being transformed in profound ways by population growth. As national numbers rise, driven by overseas migration and internal shifts, the forces shaping where and how people buy or sell homes are evolving rapidly. From affordability crises to surging demand in regional areas, demographic trends are rewriting long‑standing assumptions about property supply, demand and investment dynamics.
Australia’s population boom and its drivers
Since the reopening of international borders, Australia has experienced some of its strongest population growth in decades. Net overseas migration has returned to levels above 440,000 annually, far exceeding pre‑pandemic averages, while interstate relocation patterns continue to shift demand toward certain regions. Census data shows Australia’s population stood at about 25.4 million in August 2021, having grown by 8.6 per cent since 2016. Forecasts suggest that by 2034 the nation could approach 31 million or more. This wave of demographic change is concentrated in key areas and is already pushing housing markets in new directions.
The mismatch between demand and supply
Population growth alone does not guarantee rising home prices—but when supply lags behind, the result is clear. Australia has been building substantially fewer dwellings than needed. Estimates suggest the annual shortfall may range from 60,000 to over 100,000 homes per year in recent years. KPMG has shown that even when new dwelling completions match population increase, rent inflation is likely to rise by about 0.3 percent per quarter—and when housing construction falls behind, rental pressure spikes even faster.
Regional and internal migration reshaping geography of demand
Population growth in Australia is not evenly distributed. Western Australia, Queensland and regional New South Wales have seen faster growth than major capitals in recent years. Perth’s annual population rise reached around 3.2 percent from mid‑2023 to mid‑2024, while South East Queensland continues to absorb a major share of interstate migrants, forecast to reach over 4.4 million people by 2031. This influx is generating extraordinary housing demand in previously moderate markets.
Capital and regional city price divergence
The property price trajectory across Australia reflects these population shifts. Since March 2020, regional areas have seen home values rise by over 56%, compared to approximately 34% in the capitals. Coastal and lifestyle towns, as well as inland regional centres such as Townsville, Rockhampton, Geraldton and Bunbury, have recorded growth rates exceeding 60%. Among capital cities, Perth, Adelaide and Brisbane have far outpaced Melbourne and Sydney in price growth: Brisbane led with nearly 69% price gains, adding roughly $364,000 in median value. Melbourne, still affected by prolonged lockdowns and internal migration losses, recorded the lowest capital growth at around 8.4%.
The elasticity of demand in rental markets
Growing populations have also driven rental pressure. CoreLogic’s national rental index increased by 37.6% since March 2020, far faster than household income growth. Regional rental markets outpaced capital cities: rents in regional areas rose more than 40%, versus about 36% in major cities. Tight vacancies mean tenants now bear much of the burden of affordability issues.
Investor appetite and housing affordability
Rapid population growth has boosted investor interest in high‑growth areas. Investors tend to target regions with rising demand and limited supply, creating upward pressure on both capital values and rental returns.
Yet this accelerating demand has raised concerns over affordability for first home buyers. Recent surveys show first‑time buyers missing out on homes due to financial pressure, ultra‑competitive bidding, and short settlement timelines. Many enter the market with low deposit levels, leading to mortgage stress and future regret.
Outlook: population propelling property into 2025 and beyond
Even as interest rates rise in 2024 and early 2025, experts forecast continued price growth. Domain and KPMG project anywhere from 3 percent to 6 percent annual increases for house prices in 2025, with Perth and Adelaide expected to grow most strongly. Apartment prices may lag, but units still expected to see mid‑single‑digit increases. A surge in population boosting demand will underpin this momentum, provided supply constraints persist.
How population growth is reshaping buying trends
Growing population triggers several key shifts in buyer behavior. Rather than dispersed buying across regions, specific areas and property types are drawing demand: emerging “million‑dollar cities” like Perth and mid‑price growth markets in Queensland and South Australia. More buyers are opting for larger homes to accommodate families and multigenerational living. Remote work flexibility has also driven demand for regional lifestyle properties, enabling buyers to trade city living for affordability and space.
Historically under‑priced suburbs are now surging. Auction examples include modest dwellings quadrupling in value within a decade—such as in Merrylands, Sydney, where a four‑bedroom home sold for nearly AU$1.98 million after selling for $660,000 in 2013. Even homes labelled “dumps” can fetch $3 million in strong markets like Brisbane’s Paddington, driven by scarcity of quality land and fierce bidding.
Sellers adapting to population‑driven market shifts
Sellers are now benefitting from high demand in growth corridors. Auctions receive unprecedented numbers of registered bidders, often resulting in near‑record clearance rates. In areas such as inner Sydney and Melbourne post‑rate cuts, renewed investor and owner‑occupier interest is revitalizing middle and inner ring neighbourhoods once overshadowed by affordability pressures in outer suburbs.
Value beyond simply price growth
Population growth reshapes more than just prices. It affects the scale and type of value people seek in real estate. Infrastructure expansion becomes critical: new housing corridors require schools, hospitals, transport and retail. Regions like South East Queensland are investing in planning to create balanced 20‑minute neighbourhoods that integrate residential and commercial developments—adding long‑term value to properties. As population surges continue, properties located near new infrastructure or planned growth zones command premium valuations.
Demographic shifts and housing lifecycle demands
An ageing population adds another layer of complexity. Australia’s share of residents aged 65 and over is expected to reach over 22 percent by 2056, putting strain on aged care infrastructure and demand for accessible housing types. Multi‑generational households, downsizers and retirees begin influencing demand for purpose‑built apartments, retirement communities or homes close to healthcare services.
Challenges: policy, taxes and sustainability
Policymakers face tension between supporting growth and mitigating overheating. Stamp duty reforms, negative gearing debates, and government incentives for first‑home buyers remain contentious. Some states are investigating off‑the‑plan contract reforms to avoid buyer exploitation. Sustaining supply pipelines requires coordination across state and local levels, especially given criticism that planning processes are too slow or restrictive for rapid growth areas like Melbourne, which is projected to reach 9 million residents by 2050.
Looking forward: what buyers and sellers must consider
As population continues to rise, buyers and sellers must think strategically. Buyers assess not only price and neighbourhood but long‑term infrastructure plans, vacancy trends, migration hotspots and demographic shifts. Sellers looking to time the market can leverage demand in growth corridors, but also must consider rising supply in new developments and shifting policy incentives.
Future opportunities may lie in regions under‑served by housing but poised for infrastructure expansion, such as parts of Queensland, northern NSW, South Australia and Western Australia. Investors keen on capital growth are focusing on areas where population growth significantly exceeds dwelling construction—and where long‑term migration and employment trends align with property fundamentals.
