Geography and the role and function of place

Adelaide – West SA4 is comprised of 20 SA2s, ranging from mature beach suburbs like Semaphore and Largs Bay along the Lefevre Peninsula to the inner-city, deindustrialised suburbs like Bowden and Hindmarsh. Adelaide – West is serviced extremely well by public transport, with buses, trams and trains connecting the SA4. The Outer Harbor Railway line services the North-Eastern corner of the SA4, with the Grange line servicing the West.

Adelaide – West has a younger population compared to Greater Adelaide as a whole. SA2s like Port Adelaide and Brompton - Hindmarsh are quickly becoming fluid areas with impressive housing diversity, servicing these younger age groups.

Since Adelaide – West is a mature, inner city SA4, opportunities for greenfield growth are very limited, hence, the majority of private dwellings built over the forecast period are in the form of apartments, redevelopments, and infill.  


Adelaide - West, within the South Australian context

Our forecasts reflect how the future population of a place is affected by both localised and bigger-picture factors - what we refer to as 'bottom-up' and 'top-down' influences.

When undertaking small area forecasts, we first have to understand the macro drivers of change. Below are some key insights from our 'top-down' forecasts published in January 2023 that set the context for each region, or SA4, and the role it plays within the state.  

This video provides a short summary of the process.

SAFi Review




Adelaide - West is forecast to grow by 53,663 persons by 2046 

Australia is set to grow by 6 million persons by 2046, with South Australia's population growth accounting for around 6% of the Australian total. South Australia's population is expected to grow by 374,527 persons by 2046. Of this growth, 14% is attributed to Adelaide - West, the 3rd largest share of growth among the 7 South Australian SA4s.

Over the past 5 years, more 20-24 year-olds migrated to Adelaide - West than any other age group with a total of 961 persons aged 20-24 settling in Adelaide-West from the rest of SA. However, Adelaide - West's age structure is forecast to skew towards older age brackets over the 25 year forecast period.  Adelaide - West shares a similar migration by age profile to Adelaide - Central and Hills SA4, attributed to their similarities in household type, size and structure within their dense inner city suburbs.



.id Small Area forecasts for Adelaide - West

Paired with a top-down view of the region, our bottom-up approach is able to forecast population and dwelling growth down to SA2 and sub SA2 levels. These granular forecasts provide a view of growth that factors in what is happening on the ground to give you the most accurate population forecasts in Australia.

"Land supply is not directly an issue for macro forecasts (national, states and territories), whereas when you undertake forecasting at the regional and particularly at the local level, it becomes largely about land and dwelling supply”. John O’Leary .id demographer.




A comprehensive and balanced view of future development 

Our forecasts incorporate research into local land use and future development from a range of public and proprietary sources.

The power in the Port

RenewalSA's 'Our Port' project takes the lion's share of Adelaide - West's dwelling growth, with Port Adelaide SA2 contributing over 3,700 dwellings and 16.7% share of the growth over the forecast period.

The prevalence of PlanSA's higher density, 'Housing Diversity Zone' within Adelaide - West means numerous activity centres have been identified within close proximity to the city. Hence, the majority of growth remains close to the city centre, with Hindmarsh - Brompton SA2 and Plympton SA2 contributing a shared 27% of total dwelling growth over the forecast period, carried by the Brompton gas works redevelopment and urban densification and verticalisation along major roads in Plympton, Plympton North and Kurralta Park. 

Population growth among the SA2s follows those with the greatest dwelling growth, with Hindmarsh - Brompton SA2, Port Adelaide SA2 and Plympton SA2 contributing 15.5%, 14.6%, and 11% to population growth by 2046 respectively. Flinders Park SA2 is forecast to receive over 1000 more persons by 2025, contributing 12% of Adelaide - West's total population growth to 2025. This is attributed to numerous developments sequenced to finish in the area by then. Notably, the Kidman Park Estate, regarded as the largest remaining infill site in Adelaide - West. Aura Estate and Gateway at Findon are all expected to finish before 2025.

West Beach SA2, Fulham SA2, and Royal Park - Hendon - Albert Park SA2 are expected to grow by 1000 persons or less by 2046 with no notable developments and limited future potential development identified.





Development Hotspots

Over the forecast period, Adelaide - West is expected to grow from 109,972 to 132,429 dwellings, an additional 22,457 dwellings by 2046.

Of the 332 development sites identified, over 80% are apartments and potential redevelopment sites, mirroring the inner city aims of urban densification and verticalisation. 

Over 70% of identified dwelling supply was used throughout the forecast period, however, sequencing that development is the challenge for our forecasters. Hindmarsh - Brompton SA2 and Port Adelaide SA2 are forecast to maintain dwelling growth to 2046, while West Lakes SA2 and Flinders Park SA2 are forecast to dip after 2025 due to dwelling capacity drying up after the completion of their respective current major developments. 

Areas of note 

  • Brompton's flagship development 'Brompton Gas Works' is expected to commence development soon, contributing significant dwelling supply to inner-city Adelaide.
  • 'Our Port' is a significant waterside precinct currently under-construction, driven by "Fletcher's Slip' and 'Dock One', poviding over 1,250 dwellings. 
  • The Parks SA2 is experiencing greenfield and redevelopment growth attributed to the redevelopment of various social housing communities along with multiple townhouse estates.
  • The 'St Clair Estate' in Woodville - Cheltenham SA2 is close to completion, with close to 150 dwellings remaining. Parallel to the estate is Port Road, identified as a zone enabling higher density development.
  • Plympton SA2 has been identified as a zone enabling higher density development. This area is expected to experience some urban densification over the 25 year forecast period.
