Jannali

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

As of November 2025, the estimated population for the suburb of Jannali is around 6,875 people. This figure reflects a growth of 243 individuals since the 2021 Census, which recorded a population of 6,632. The latest estimate is inferred from AreaSearch's validation of new addresses and examination of ABS's ERP data release in June 2024, indicating a resident population of 6,861. This growth represents a density ratio of 2,794 persons per square kilometer, placing Jannali in the upper quartile compared to other national locations assessed by AreaSearch. The suburb's 3.7% growth since the 2021 Census exceeded the SA3 area average of 2.6%. Overseas migration contributed approximately 63.0% of overall population gains during recent periods.

For future projections, AreaSearch is using ABS/Geoscience Australia's SA2 level projections released in 2024 with a base year of 2022. By 2041, the suburb is expected to expand by 524 persons, reflecting an increase of 5.3% over the 17 years based on aggregated SA2-level projections.

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

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, indicates Jannali has experienced around 30 dwellings receiving development approval each year. Over the past five financial years, between FY-21 and FY-25, approximately 151 homes were approved, with a further six approved in FY-26 so far. This results in an average of about 0.9 people moving to the area for each dwelling built over these five years, suggesting supply is meeting or surpassing demand.

New properties are constructed at an average expected cost value of $548,000. There have also been $16.0 million in commercial approvals this financial year, indicating moderate levels of commercial development. Relative to Greater Sydney, Jannali records elevated construction activity, with 45.0% above the regional average per person over the past five years.

Recent construction comprises 55.0% detached houses and 45.0% townhouses or apartments, providing options across different price points. The location has approximately 278 people per dwelling approval, indicating a low density market. According to AreaSearch's latest quarterly estimate, Jannali is expected to grow by 365 residents through to 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.

Notably, education & training employed 1.3 times the regional average. Manufacturing, however, employed only 4.0% of local workers, below Greater Sydney's 5.7%. The area appears to offer limited employment opportunities locally, as indicated by a comparison between Census working population and resident population. Over a 12-month period ending in June 2025, employment increased by 2.6%, while the labour force grew by 3.1%, causing the unemployment rate to rise by 0.4 percentage points. By comparison, Greater Sydney recorded employment growth of 2.6%, labour force growth of 2.9%, with unemployment rising 0.3 percentage points. Jobs and Skills Australia's national employment forecasts from Sep-22 suggest that national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, although growth rates differ significantly between industry sectors. Applying these projections to Jannali's employment mix suggests local employment should increase by approximately 6.9% over five years and 14.0% over ten years, assuming constant population projections.
