Jannali

Jannali has seen population growth performance typically on par with national averages when looking at short and medium term trends

As of Feb 2026, the population of the suburb of Jannali is estimated at around 6,946, reflecting an increase of 314 people since the 2021 Census. This increase represents a growth rate of 4.7%. The population estimate is based on AreaSearch's validation of new addresses and analysis of ABS data, including the resident population of 6,856 estimated in June 2024. This level of population results in a density ratio of 2,823 persons per square kilometer, placing Jannali in the upper quartile relative to national locations assessed by AreaSearch. The suburb's growth since the 2021 Census exceeded both its SA3 area (3.1%) and SA4 region, marking it as a growth leader. Overseas migration contributed approximately 63.0% of overall population gains during recent periods.

For future projections, AreaSearch is adopting ABS/Geoscience Australia's SA2 level projections released in 2024 with 2022 as the base year, and NSW State Government's SA2 level projections released in 2022 with 2021 as the base year for areas not covered by ABS data. Based on these aggregations, Jannali is expected to expand by 540 persons to 2041, reflecting an increase of 6.5% over the 17-year period.

Residential development activity is lower than average in Jannali according to AreaSearch's national comparison of local real estate markets

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Jannali has experienced around 29 dwellings receiving development approval each year. An estimated 148 homes were approved over the past five financial years, between FY-21 and FY-25, with a further 12 approved so far in FY-26. On average, 0.8 people have moved to the area for each dwelling built over these years, indicating that supply is meeting or surpassing demand.

This has provided greater buyer choice while supporting potential population growth above projections. New properties are constructed at an average value of $548,000, demonstrating a focus on the premium segment with upmarket properties. Additionally, $16.0 million in commercial approvals have been registered this financial year, indicating steady commercial investment activity.

Compared to Greater Sydney, Jannali records elevated construction levels, 42.0% above the regional average per person over the past five years. This has maintained good buyer choice while supporting existing property values. However, development activity has moderated in recent periods. New development consists of 54.0% detached houses and 46.0% townhouses or apartments, offering choices across price ranges from spacious family homes to more compact options. With around 310 people per dwelling approval, Jannali shows characteristics of a low density area. Looking ahead, Jannali is expected to grow by approximately 450 residents through to 2041, according to the latest AreaSearch quarterly estimate. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
