Cobblebank

Cobblebank lies within the top 10% of areas nationally in terms of population growth performance according to AreaSearch analysis of short and medium-term trends

As of Feb 2026, the population of the suburb of Cobblebank is estimated at around 5,662 people. This reflects an increase of 2,061 people since the 2021 Census, which reported a population of 3,601 people. The change is inferred from the resident population of 4,743, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 298 validated new addresses since the Census date. This level of population equates to a density ratio of 749 persons per square kilometer. Cobblebank's growth rate of 57.2% since the 2021 census exceeded both the national average (9.9%) and state averages, marking it as a growth leader in the region. Population growth was primarily driven by interstate migration contributing approximately 74.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area released in 2024 with 2022 as the base year, and VIC State Government's Regional/LGA projections released in 2023 for areas not covered by this data. Exceptional growth is predicted over the period from 2026 to 2041, with the suburb expected to increase by 7,919 persons based on aggregated SA2-level projections, reflecting an increase of 138.4% in total over the 17 years.

The level of residential development activity in Cobblebank was found to be higher than 90% of real estate markets across the country

AreaSearch analysis indicates Cobblebank has seen approximately 129 new homes approved annually. Between FY-21 and FY-25, around 646 homes were approved, with a further 26 approved in FY-26 to date. Each home built over these years is estimated to accommodate an average of 5.5 new residents.

This demand exceeds supply, potentially driving price growth and increased buyer competition. New properties are constructed at an average cost of $337,000. In FY-26, commercial approvals totalled $764,000, reflecting the area's residential nature. Cobblebank's construction activity is 49.0% above Greater Melbourne's regional average per person over the past five years, indicating strong developer confidence.

Recent construction comprises 96.0% detached houses and 4.0% medium to high-density housing, preserving the area's low density character while attracting space-seeking buyers. There are approximately 52 people per dwelling approval in Cobblebank, suggesting an expanding market. By 2041, AreaSearch projects Cobblebank will add around 7,836 residents. Construction maintains a reasonable pace with projected growth, although increasing population may intensify buyer competition.

Employment opportunities locally may be limited, as indicated by the difference between the working population and resident population counts.

In contrast, Greater Melbourne experienced employment growth of 3.0% and labour force growth of 3.3%, with a 0.3 percentage point increase in unemployment. Jobs and Skills Australia's national employment forecasts from May-25 suggest that national employment will expand by 6.6% over five years and 13.7% over ten years, but growth rates vary significantly between industry sectors. Applying these projections to Cobblebank's employment mix suggests local employment should increase by 6.3% over five years and 13.1% over ten years.
