Cobblebank
A population that grew 2,216% in 10 years and a median age of 29 (11 years below national) mark Cobblebank as one of Melbourne's most aggressively expanding greenfield suburbs. Household income sits at the 71.9th percentile nationally, yet 99.7% of dwellings are separate houses and 61.7% of residents carry a mortgage, painting a portrait of young families who stretched to buy land on the western edge of the city. With 51.2% of residents born overseas (29.6 points above national) and Punjabi the most spoken non-English language, the community reflects Melbourne's broader migration patterns arriving in newer outer suburbs before inner areas.

The median house price reached $667,500 in the April-June 2024 quarter, up from $610,000 in October-December 2023 but still 2.3% below the peak of $683,500 in July-September 2023. Since 2013 the median has doubled, rising 99% from $335,500 over 14 years at a 5% CAGR. The stock is overwhelmingly separate houses (99.7%), and 77.9% of homes have 4 or more bedrooms, which is typical of greenfield estates built to family scale. Monthly mortgage repayments average $1,850, giving a mortgage-to-income ratio of 22.3%, which is comfortably below the 30% stress threshold. Just 4.9% of households own outright, reflecting how recently most properties were purchased.

For Investors
Renters make up 33.5% of the market and weekly rent is $370, giving a gross yield near 2.9% against the $667,500 median, below the national average for houses. The vacancy rate of 5.1% is elevated, signalling that rental supply is ahead of demand at this stage of the suburb's buildout. Internal migration drives growth strongly, with a net annual inflow of 940 residents compared to 71 from overseas. Population is forecast to reach approximately 15,919 by 2031 under medium projections from the current 12,885, an annual increment of roughly 800 persons (6.2%). Development activity is modest at 9 applications in 12 months, which is consistent with a suburb where most lots have already been developed in recent estates rather than infill.

Demographics
The median age of 29 is 11 years below the national figure, one of the starkest age differentials you will find in metropolitan Victoria. Average household size is 3.4, which is 0.9 above national, driven by the 2,102 couple-with-children families that represent the dominant household type. The overseas-born share of 51.2% runs 29.6 points above national, with Indian ancestry (645 residents) and Filipino ancestry (217 residents) the largest identifiable migrant groups after the broad-other category. Punjabi is spoken by 489 residents, making it by far the most common non-English language. University qualifications reach 39.3%, which is 9.2 points above national, suggesting the migrant cohort is relatively skilled rather than low-skilled.

The price trajectory runs from $335,500 in 2013 to a peak of $683,500 in mid-2023, then a modest correction to $667,500 by mid-2024, a 2.3% pullback from the peak. Over the full 14-year period the CAGR is 5.0%. Separate houses make up 99.7% of stock, semi-detached only 0.3%, and apartments are effectively absent, so buyers are purchasing land and house packages in a greenfield setting rather than competing for established units. The 4-plus bedroom category covers 77.9% of homes and 3-bedroom accounts for 22.1%, confirming that the estate was built for growing families rather than downsizers. Tenure splits 61.7% mortgaged, 33.5% renting and just 4.9% owned outright, compared to the national owned-outright figure which tends to be far higher in established areas.

Economy & Employment
Healthcare employs the largest share of residents (19.9%, 221 workers), followed closely by Transport at 16.9% (188 workers). Construction contributes 8.6% (95 workers) and Retail 8.8% (98 workers). By occupation, Machinery and Drivers (295) lead, pointing to the significant logistics and trade workforce in the western corridor. Unemployment stands at 9.0%, above the national average, which partly reflects the young age profile where more residents are still entering the workforce. The full-time employment rate is 68.9% among those employed. SEIFA tells a nuanced story: IRSAD decile 6 and IRSD decile 5 show a suburb at roughly mid-range on disadvantage nationally, while the IER decile of 8 indicates better access to economic resources, consistent with the 71.9th-percentile household income.

Transport to Work
Car dependence is extreme: 89.8% of residents drive to work compared to the national average, and only 4.0% use public transport. Walking and cycling account for just 0.4% of commutes, reflecting the low-density, car-oriented layout typical of outer greenfield estates. The crime rate of 62.2 incidents per 1,000 residents is a useful benchmark, with property and deception offences accounting for 121 of 224 total incidents. IRSAD decile 6 places Cobblebank at the national mid-range for advantage and disadvantage. No schools are recorded within the suburb boundary in the dataset, though the surrounding Melton area has multiple primary and secondary schools servicing the growth corridor. The rent-to-income ratio of 19.3% is below the 30% stress threshold, and mortgage-to-income at 22.3% is also manageable.

Population Forecast

High GrowthCobblebank's 10-year population growth of 2,216% is extraordinary, driven by the release of greenfield residential land in the Melton Growth Corridor. The current population of approximately 12,885 (2025) is forecast to reach 15,919 by 2031 under medium projections. Annual growth runs at 6.2%, or around 800 additional residents per year, driven primarily by internal migration (net 940 per year) rather than overseas arrivals (net 71). Real incomes grew 40.5% over the decade, above the national average, and the working-age share of the population rose 0.8 points while the senior share fell 0.9 points, consistent with ongoing in-migration of young families. Affordability has tightened sharply, with the affordability index falling from 82.7 in 2011 to 39.5 in 2021, reflecting land price appreciation that outpaced income growth.

Is Cobblebank good for property investment?
The investment case rests on population growth rather than yield. Weekly rent of $370 against a $667,500 median implies a gross yield near 2.9%, below national averages. The vacancy rate of 5.1% is elevated, suggesting near-term rental supply excess. However, population is forecast to grow from 12,885 to 15,919 by 2031, an annual increment of roughly 800 residents, which should absorb current oversupply over time.

Indian ancestry is the largest identifiable overseas-born group at 645 residents, reflecting Melbourne's broader South Asian migration patterns arriving in outer growth corridors.
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.
