Kilsyth South
A 42-year median age and a 97.5% separate-house share give Kilsyth South a settled, family-oriented profile, while household income sits at the 88.7th percentile. Its 2,862 residents live at a density of 853.5 people per square kilometre, and 53.2% of households are paying a mortgage. The suburb's 2,862-resident scale is a useful contrast point when comparing Kilsyth South with nearby Kilsyth and Mooroolbark. Long-term residents account for 88.2% of the population, helping explain the low 5.3% rental share and the strong concentration of four-plus-bedroom homes at 57.9%.

Only a handful of houses sold here in this period, so this median can jump sharply from one quarter to the next for reasons that have nothing to do with the market. Treat it as a rough guide, not a settled price.
A $1,950 monthly mortgage equals 19.3% of household income, and the mortgage stress flag is false. Compared with the 2.5% semi-detached share, the housing stock is clearly oriented toward established family households.
For Buyers
A $1,950 monthly mortgage equals 19.3% of household income, and the mortgage stress flag is false. Compared with the 2.5% semi-detached share, the housing stock is clearly oriented toward established family households.
For Investors
Investor demand is shaped by an owner-heavy tenure mix: only 5.3% of households rent, lower than the 41.5% owning outright and the 53.2% paying a mortgage. The $426 weekly rent and 2.9% vacancy rate point to an established rental market, while rent growth of 37.0% is higher than the 16.8% real-income growth figure. Development activity was 0 in the latest 12 months, so new supply is not a visible short-term offset. Balanced migration and a 1.06% annual growth trend support a measured strategy, with yield, property condition and tenant demand more important than a rapid-growth thesis.

Economy & Employment
Household income is at the 88.7th percentile, above the midpoint, while labour-force participation reaches 73.2% and unemployment is 3.4%. Employment is concentrated in healthcare at 16.8% with 172 workers, construction at 15.9% with 163, education at 12.1% with 124, manufacturing at 10.7% with 109 and retail at 7.1% with 73. Occupations reinforce this practical mix: trades account for 342 people and professionals 312, ahead of clerical and administration at 237. SEIFA is more middle-range than the income percentile suggests, with IEO decile 5, IER 6, IRSD 5 and IRSAD 5. That difference may reflect household earnings not translating uniformly into education or area-wide advantage.

Transport to Work
Daily life is car-oriented: 69.1% drive to work, compared with 1.4% using public transport and 1.5% walking or cycling, while 23.9% work from home. That makes private vehicle access more important than transit proximity for many households. Recorded crime was 116 offences, or 40.5 per 1,000 residents; property and deception offences accounted for 63, compared with 21 crimes against the person and 23 justice procedures offences. The IRSAD decile is 5, indicating middle-range relative advantage rather than a top-decile setting. Families should check enrolment zones against the exact address because boundaries can cross suburb lines. A 16.0% volunteering rate adds a participation signal.

Growth Outlook
Kilsyth South is forecast to grow at 1.06% annually, with migration classified as Balanced and the trajectory marked Growing (all ages). Population change across the wider area is 16.2% over 10 years, while the shift profile records rent growth of 37.0% versus real-income growth of 16.8%, which can tighten affordability even as the affordability trend is labelled Improving. Gentrification is scored at 18 and staged Not gentrifying, while the shift profile records a score of 35 and Early signs. This points to gradual broad-based expansion rather than a sharp demographic reset, because growth is spread across age groups and migration is not dominated by one source.

Frequently Asked Questions
Is Kilsyth South a good suburb to live in?
It can suit households wanting established detached housing, because 97.5% of dwellings are separate houses and 57.9% have 4 or more bedrooms. Car dependence is high at 69.1%, while the recorded crime rate is 40.5 offences per 1,000 residents, so lifestyle fit depends on transport and street-level priorities.
What schools are in Kilsyth South?
School options should be checked using the exact address and current enrolment zones, since boundaries can cross suburb lines. Compared with relying on the suburb name alone, direct verification is more useful for families. Kilsyth South has 2,862 residents and a 42-year median age, but nearby government, Catholic and independent choices should be confirmed directly.
Is Kilsyth South safe?
No single statistic can determine safety. Kilsyth South recorded 116 offences, equal to 40.5 per 1,000 residents; property and deception offences were 63, compared with 21 crimes against the person. Check recent incidents by street and time, because the suburb-wide rate can differ from conditions around a particular home.
How is Kilsyth South's population changing?
The population trend is positive but measured. Kilsyth South has 2,862 residents today, and the wider-area forecast indicates 1.06% annual growth with a Growing (all ages) trajectory. Change across 10 years is 16.2%, while migration is Balanced and gentrification is scored 18, staged Not gentrifying. That suggests gradual change rather than a sharp redevelopment cycle.
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.
