Jannali

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

Based on ABS population updates and AreaSearch validations, as of Nov 2025, Jannali's estimated population is around 6,947. This reflects an increase of 315 people since the 2021 Census, which reported a population of 6,632. The change was inferred from AreaSearch's estimate of 6,856 residents following examination of ABS ERP data release in June 2024 and additional 36 validated new addresses since the Census date. This results in a density ratio of 2,824 persons per square kilometer, placing Jannali in the upper quartile nationally according to AreaSearch assessments.

Overseas migration contributed approximately 63.0% of overall population gains during recent periods.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered by this data, NSW State Government's SA2-level projections from 2022 using 2021 as the base year are utilised. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Future population dynamics anticipate a median increase nationally, with Jannali expected to expand by 521 persons to 2041 based on aggregated SA2-level projections, reflecting an overall increase of 4.2% over the 17 years.

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. Over the past 5 financial years, between FY-21 and FY-25, an estimated 149 homes were approved, with a further 10 approved so far in FY-26. This indicates that supply is meeting or surpassing demand, providing greater buyer choice while supporting potential for population growth above projections.

The average number of people moving to the area per dwelling built over these years was 0.9. New properties are constructed at an average value of $548,000, demonstrating a focus on the premium segment with upmarket properties. In terms of commercial approvals, $16.0 million has been registered this financial year, indicating steady commercial investment activity in Jannali.

Compared to Greater Sydney, Jannali records somewhat elevated construction activity, at 43.0% above the regional average per person over the past 5 years. This maintains good buyer choice while supporting existing property values, although development activity has moderated in recent periods. New development consists of 54.0% detached houses and 46.0% townhouses or apartments, featuring an increasing blend of attached housing types offering choices across price ranges, from spacious family homes to more accessible compact options. With around 311 people per dwelling approval, Jannali shows characteristics of a low density area. Looking ahead, Jannali is expected to grow by 290 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.
