Langwarrin South
Household income at the 95.9th percentile nationally sits alongside a crime rate of only 45.3 incidents per 1,000 residents, making Langwarrin South one of the Mornington Peninsula's higher-income, lower-density pockets. The suburb covers 8.78 square kilometres and holds just 1,346 residents, giving a density of 153 people per km2, far below most metropolitan Melbourne suburbs. Almost all dwellings are separate houses (99.2%) and 69.1% have four or more bedrooms, a profile shaped by its rural-fringe character. The median age of 42 sits 2 years above the national figure, and the population has grown 10.9% over the past decade, driven primarily by overseas migration rather than internal movement.

No recent median house price data is recorded for Langwarrin South, which reflects the suburb's small transaction volume given its population of 1,346. What the data does show is that 99.2% of homes are separate houses with 69.1% carrying four or more bedrooms, so buyers are competing in a market dominated by large detached homes on sizable lots. Monthly mortgage repayments average $2,600 and the mortgage-to-income ratio sits at 21.7%, comfortably below the 30% stress threshold and lower than the national average. The ownership rate is high: 42.2% own outright and 53.7% hold a mortgage, compared to a national renter share around 30%, leaving only 4.1% renting. Buyers looking for space at a manageable repayment burden relative to income will find the debt-servicing costs here less strained than in inner-ring Melbourne.

For Investors
The investor case for Langwarrin South is cautious. Weekly rent averages $346 and the vacancy rate sits at 4.1%, above the typical threshold of 3% considered balanced, which signals limited rental demand pressure. Only 4.1% of residents rent, well below the national average, so the rental pool is thin. On the positive side, rent grew 30.4% over the past decade and net overseas migration adds 118 residents per year to the broader area, which supports gradual demand. Development activity ran at 10 applications in the past 12 months, with recent permits including 2-lot subdivision works, indicating small-scale land supply growth. Gross yields remain difficult to estimate without a published median price, but the combination of high vacancy and low renter share means investors should verify local demand before committing.

Overseas-born residents account for 14.8% of the population, which is 6.8 percentage points below the national average, reflecting an Anglo-leaning ancestry profile dominated by English (577), Scottish (173) and Irish (133) backgrounds. University qualifications reach 28.1%, which is 2 percentage points below the national benchmark.

Tenure
The housing stock in Langwarrin South is almost entirely detached houses (99.2%), with apartment dwellings accounting for only 0.8%, well below the national mix. Four-plus bedroom homes make up 69.1% of all dwellings, and three-bedroom homes a further 24.2%, confirming this is a suburb built for large families rather than downsizers or renters. Tenure is heavily owner-occupied: 42.2% own outright and 53.7% carry a mortgage, leaving just 4.1% renting, far below the national renter share. Monthly mortgage repayments of $2,600 and a mortgage-to-income ratio of 21.7% suggest buyers are not overextended relative to their incomes, which sit at the 95.9th percentile nationally. Median house price data is not available, likely because the small annual transaction volume in a 1,346-person suburb cannot generate a statistically stable median.

Economy & Employment
Construction is the dominant industry at 27.6% of local workers (127 people), a concentration that is above typical metropolitan suburb rates and reflects the rural-fringe character of the area where property development and trades are core employment. Healthcare follows at 13.9% (64 workers) and Professional/Technical services at 11.1% (51 workers), pointing to a mix of blue-collar trades and white-collar knowledge work. By occupation, Professionals (123) and Clerical/Admin (121) are the top two categories, followed closely by Managers (105). The unemployment rate is 2.9%, below the national rate, and the full-time employment rate is 57.7%. SEIFA scores show an IER decile of 8 (economic resources, above the national median) while IEO decile sits at 5 (education and occupation, at the national median), suggesting wealth without the educational attainment typically associated with it.

Transport to Work
Car dependency is high with 89.4% of residents driving to work, above the national average, which reflects the suburb's low density and limited public transport options in a 8.78 km2 rural-fringe footprint. No schools are recorded inside the suburb boundary, so families depend on institutions in neighbouring Langwarrin or Frankston areas. The crime rate of 45.3 incidents per 1,000 residents covers 61 total offences, with property and deception offences the largest category at 31 cases, followed by crimes against the person at 17. IRSAD decile is 6, placing Langwarrin South at moderate advantage nationally. Rent-to-income at 12.5% is well below stress thresholds, and only 3.6% of residents require daily assistance, consistent with a relatively young working-age core within an aging trajectory suburb.

Population Forecast

(+218 people/yr)
EstablishedLangwarrin South's population grew 10.9% over the past decade, reaching 1,346 residents, and medium forecasts for the broader area project steady expansion to 27,420 by 2031. The annual growth rate is 0.85% and the area adds around 218 persons per year. The trajectory is aging, with the senior share rising 5.4 points since 2011, and net internal migration is negative (minus 147 per year) while overseas migration contributes 118 arrivals annually, so overseas arrivals are the growth driver. Gentrification is classified as early signs with a score of 30, supported by a 10.9% population rise and real income growth of 12.6% over the period. Affordability improved from 44.7% in 2011 to 42.1% in 2021, a modest but positive shift compared to many Mornington Peninsula suburbs that tightened over the same period.

Household income sits in the 95.9th percentile nationally and the mortgage-to-income ratio is 21.7%, below stress levels. The main trade-offs are high car dependency (89.4% drive), no schools inside the suburb boundary, and a thin rental market with 4.1% vacancy.
What is the median house price in Langwarrin South?
A statistically stable median house price is not available for Langwarrin South, likely because the suburb's population of 1,346 generates too few annual transactions.

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.
