Jannali
Three of four SEIFA indexes place this Sutherland Shire pocket in decile 10, the top advantage tier nationally, yet the median house price fell 18.5% from $1,350,000 in 2024 to $1,100,000 in 2025, one of the sharper one-year corrections you will see in an established market. Household income sits in the 84.3rd percentile and 71% of dwellings are owner-occupied through outright ownership or a mortgage, so the area reads as settled rather than speculative. The population of 6,632 grows just 0.41% a year, university qualifications run 8.2 points above the national figure, and the median age of 39 is 1.0 year below national, a slightly younger profile than the aging trajectory of the wider Shire.

2024-2025 (PSI derived)
The recorded median house price of $1,212,500 sits between a 2024 peak of $1,350,000 and a 2025 figure of $1,100,000, an 18.5% drop that hands buyers far more leverage than a year earlier. Stock favours families: 51.1% of dwellings are separate houses, 36.1% have three bedrooms and 28.8% carry four or more, so detached living dominates over the 23.0% apartment share. Monthly mortgage repayments average $2,600, producing a mortgage-to-income ratio of 27.0%, below the 30% stress threshold even before the price correction. Mortgage holders at 41.2% outnumber both outright owners at 29.7% and renters at 29.1%, which signals a market still being bought into by working households rather than held purely by debt-free retirees.

For Investors
Renters make up 29.1% of households and weekly rent averages $428, which against the $1,212,500 median implies a gross yield near 1.8%, thin but better than premium harbour suburbs. The vacancy rate of 5.5% is moderate, leaving some softness in the small apartment segment that is only 23.0% of stock. Demand support is real: net overseas migration adds 168 residents a year against a net internal outflow of 86, and rents have grown 33.3% over the decade, faster than the slow 0.41% annual population gain. Development is modest at 44 applications in 12 months, weighted toward dual occupancy and secondary dwellings rather than apartment towers, so future rental supply stays constrained and supports existing landlords on rent escalation more than volume.

Demographics
The median age of 39 is 1.0 year below the national figure, younger than the aging Sutherland Shire around it, though the trajectory still tilts older as the senior share rose 3.6 points and the working-age share fell 3.1 points over the decade. Overseas-born residents reach 22.7%, just 1.1 points above national, and ancestry leans Anglo-Celtic, led by English (2,642), Irish (858) and Scottish (620). University qualifications at 38.3% run 8.2 points above national, which explains why Professionals (949) and Managers (552) are the two largest occupation groups. Average household size is 2.6, 0.1 above national, consistent with a family base where couples with children (2,577) outnumber couples without (1,225). The leading non-English languages are Mandarin (58), Greek (35) and Cantonese (31).

Tenure
Tenure is owner-dominated: 41.2% carry a mortgage, 29.7% own outright and 29.1% rent, so 71% of households are owners, well above the renter-heavy inner city. The stock is 51.1% separate houses, 25.5% semi-detached and 23.0% apartments, a detached-house weighting that supports family demand and keeps the market from the oversupply seen in apartment suburbs. Three-bedroom dwellings lead at 36.1% with four-plus at 28.8%, so larger homes are the norm. The median house price fell from $1,350,000 in 2024 to $1,100,000 in 2025, an 18.5% correction, while the recorded median reads $1,212,500. Mortgage-to-income at 27.0% and rent-to-income at 19.3% both sit below the 30% stress threshold, a comfort buffer earned by incomes in the 84.3rd percentile rather than by cheap housing.

Economy & Employment
The workforce concentrates in stable service sectors: Healthcare leads at 14.4% (358 workers), Education follows at 13.5% (336) and Professional/Tech at 12.8% (318), with Construction at 9.6% and Finance at 8.3%. By occupation Professionals (949) and Managers (552) dominate, aligning with the decile 9 IEO score for education and occupation. Unemployment is low at 4.0% and the full-time employment rate is 65.6%, while participation reads 57.8%, held down because 1,542 residents sit outside the labour force in an area with a rising senior share. The IER score for economic resources reaches decile 10, the top tier, reflecting the 71% owner-occupier base, and real incomes grew 17.6% over the decade, evidence of a financially secure rather than transient population.

Transport to Work
The area scores decile 10 on IRSAD, the top advantage tier nationally, and decile 10 on IRSD for relative disadvantage, meaning very few residents face deprivation, though 6.3% (399 people) still need daily assistance given the older skew. Transport leans on the car at 79.7% of commuters, with only 11.4% using public transport and 3.4% walking or cycling, below the patterns of inner-city suburbs and typical of a detached-house area at 2,657 residents per km2. No schools are recorded inside the 2.5 km2 boundary in this dataset, so families rely on institutions in neighbouring Sutherland Shire suburbs. Volunteering at 14.9% and rent-to-income of 19.3% point to a settled community with comfortable housing costs relative to its 84.3rd-percentile incomes.

Population Forecast
+0.41%/yr
(+93 people/yr)
EstablishedGrowth is slow and steady: the population rises 0.41% a year, about 93 people, and climbed 6.9% over the past decade, classifying the area as an established suburb rather than a growth front. Overseas migration is the only positive driver at a net 168 residents a year, offset by a net internal outflow of 86, so natural expansion is thin. The gentrification reading shows early signs with a score of 36, supported by rent growth of 33.3% and real income growth of 17.6% over the decade, but the underlying trajectory is aging, with the senior share up 3.6 points and the working-age share down 3.1 points. Affordability improved from 51.0% in 2011 to 47.0% in 2021, easing pressure even as the area held its decile 10 advantage standing.

Is Jannali good for property investment?
Rent of $428 a week against a $1,212,500 median gives a gross yield near 1.8%, and the vacancy rate is a moderate 5.5%. Net overseas migration of 168 a year and rent growth of 33.3% over the decade support demand, but slow 0.41% population growth means returns lean on capital growth and rent escalation.

How to read these comparisons
Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.
Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.
Data sources: ABS 2021 Census (demographics, income, tenure), state Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
