This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Overseas migration contributed approximately 91.0% of overall population gains in recent periods.
AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data and years post-2032, the SA State Government's Regional/LGA projections are adopted, based on 2021 data and released in 2023.

Development
AreaSearch analysis of residential development drivers sees Allenby Gardens recording a relatively average level of approval activity when compared to local markets analysed countrywide
Allenby Gardens has seen approximately six dwelling approvals annually based on AreaSearch analysis of ABS building approval numbers. Around 30 homes were approved between financial years FY21 to FY25, with seven more approved in FY26 as of current data. On average, about 1.8 new residents have moved into new homes each year over the past five financial years, indicating a balanced supply and demand until recently when it moderated to -0.6 people per dwelling over the last two years.
New homes are being built at an average construction cost value of $404,000, targeting the premium market segment. Compared to Greater Adelaide, Allenby Gardens has significantly less development activity, 67.0% below the regional average per person. This constrained new construction typically reinforces demand and pricing for existing dwellings, although building activity has accelerated in recent years. Nationally, this activity is also lower, reflecting market maturity and possible development constraints. New building activity comprises 25.0% detached dwellings and 75.0% townhouses or apartments, marking a significant shift from the current housing pattern of 74.0% houses. This focus on higher-density living creates more affordable entry points for downsizers, investors, and first-home buyers. Population forecasts suggest Allenby Gardens will gain 434 residents by 2041.
If current construction levels persist, housing supply may lag population growth, potentially intensifying buyer competition and supporting price growth. The area reflects a low density with around 173 people per approval.
