Austral in South West Sydney is rapidly emerging as a high growth suburb attracting strong interest from first home buyers, families and investors searching for house and land packages in a well-connected corridor.
Located approximately 20km from the future Western Sydney International Airport and positioned within the South West Growth Area, Austral sits at the centre of large-scale infrastructure investment and long-term urban planning. As employment hubs expand and transport connections improve, demand for new homes across South West Sydney continues to strengthen.
Developers are responding to this demand by delivering new residential communities designed for modern suburban living. Castle Group is helping shape this growth building several communities across Austral, including Kemps Estate, Central Grove, Ed.Ave and Bloomfield, each offering different lifestyle and price options for buyers entering the South West Sydney market.
When considering Austral property and land opportunities, it’s important to understand what’s fuelling demand in this area. The suburb’s continued growth is backed by three main drivers: strong population growth, infrastructure investment and growing local employment 1.
1. Population Growth Supporting Long-term Housing Demand
Population growth is one of the strongest indicators of sustained property demand.
Liverpool City Council forecasts that Austral’s population will grow from approximately 18,360 residents in 2025 to around 50,921 by 2041. 2 This reflects an average annual growth rate of about 6.1%, significantly exceeding the Greater Sydney average of 1.1% over the same period 1.
This growth is mostly being driven by young families, working professionals and newly arrived residents from overseas looking for affordable homes in South West Sydney.
New communities like Kemps Estate offer an accessible entry point into the property market. Positioned within Austral’s green residential areas, Kemps Estate offers some of the most affordable land opportunities in the suburb, making it attractive for young families and multigenerational households seeking long-term lifestyle value.
For home buyers considering house and land packages in Austral, steady population growth signals continued demand for homes and community infrastructure. For investors, it supports rental demand over time.
2. Infrastructure Investments Transforming South West Sydney
A wave of transformative infrastructure development projects is reshaping the region.
Western Sydney International Airport: A major international hub opening in 2026 1.
The Western Sydney Aerotropolis: Positioned around the new Western Sydney International Airport, the Aerotropolis will become a global hub for industries such as aerospace, logistics, health, and education. With Bradfield City, Australia’s first new city in over a century at its centre, it will offer Austral residents direct access to attractions, amenities, and new economic opportunities1.
The Fifteenth Avenue Smart Transit (FAST) Corridor: A dedicated smart bus transit route providing fast access from Liverpool CBD through Austral to the airport1.
Sydney Metro Western Sydney Airport Line: A new metro line linking St Marys to the Aerotropolis, enhancing rail connectivity for the region1.
These projects will boost connectivity and employment opportunities , as well as drive property value across the region.
Properties positioned close to these future infrastructure corridors most likely will benefit the most. Central Grove, located directly along Fifteenth Avenue near the future FAST Transit Corridor offers buyers a rare opportunity to secure land in one of Austral’s most strategically located growth areas.
3. Employment Centres Near Austral
Proximity to job centres is crucial for residential growth, with demand rising in areas that offer convenient commutes to employment opportunities.
Residents in Austral enjoy easy access to major high-skilled employment centres in neighbouring LGAs (local government areas) like Liverpool, Camden, Canterbury-Bankstown, and Campbelltown. The future Western Sydney Aerotropolis, expected to add over 200,000 jobs, further enhances this advantage. These hubs support a diverse range of industries including healthcare, education, logistics, tech and advanced manufacturing1.
Central Grove and Ed.Ave are particularly appealing to first home buyers and investors in Sydney area, offering walkable access to town centres and transport, with easy connections to major employment corridors across Western Sydney.
4. Lifestyle and Amenities
The Austral-Leppington Structure Plan plans for a revitalised community supported by key infrastructure and amenities, including a new town centre in Austral with 30,000 sqm of retail space, three Neighbourhood Centres, five primary schools, one high school, and 220 hectares of land allocated for employment uses2.
With a strong focus on liveability, the plan ensures everyday convenience for families, placing essential services, schools, shops, and parks within easy reach.
Ed.Ave has been planned around this lifestyle vision, offering a easy access to town centre amenities, schools, parks and retail, creating a convenient environment for young families and professionals seeking connected suburban living.
5. Transport, Major Road Upgrades and Connectivity
Austral offers easy access to key Sydney destinations because of its location near the Leppington train station, offering direct links to Liverpool (~20 minutes), Parramatta (~52 minutes), and the CBD (~55 minutes).
With upgraded links via Bringelly Road, the M5 and the M7, residents benefit from smoother traffic flow and better commute options. Upcoming projects like the FAST Transit Corridor and new metro line will make getting around Western Sydney even easier1.
6. Austral Property and Rental Market
According to an Urbis report on the Austral Study Area, house and vacant land prices achieved average annual growth rates of 4.7% and 6.8% respectively between 2014 and 2024. 1 More recently, median house prices have climbed from $842,500 to $991,000 in just one year, which is an annual compound growth rate of 16.6% as reported by Realestate.com.au. 3. With ongoing population growth, limited housing supply, and major projects underway, demand is expected to remain strong, reinforcing the suburb’s potential for long-term capital gains.
Bloomfield, with its wide and deep blocks of land, and north facing backyard options, appeals to families and upsizers looking for homes that utilise natural light and outdoor living.
7. Rental Yield
In October 2024, Austral recorded an average house rental yield of 5.3%, higher than the Greater Sydney average of 2.8%.
Data from the NSW Department of Housing shows that the median weekly rent for houses in Austral increased from $590 in the September quarter of 2021 to $760 by the same quarter in 2024. This represents an average annual rental growth rate of 8.8%.
The combination of relatively low vacancy rates of 2.8% and strong rental yields in Austral suggests a promising opportunity for steady rental income and future market growth, which are key factors that make the area appealing to investors4.
