Based on ABS population updates and AreaSearch validation, the estimated population of Rockbank as of Feb 2026 is around 5,415. This reflects an increase of 2,832 people since the 2021 Census, which reported a population of 2,583. The change was inferred from AreaSearch's estimation of resident population at 3,132 following examination of ABS's latest ERP data release in June 2024 and an additional 673 validated new addresses since the Census date. This level of population results in a density ratio of 1,247 persons per square kilometer, above the national average assessed by AreaSearch. Rockbank's growth rate of 109.6% since the 2021 census exceeded both national (9.9%) and state averages, marking it as a growth leader. Interstate migration contributed approximately 85.0% of overall population gains during recent periods, with all drivers including natural growth and overseas migration being positive factors.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered by this data, AreaSearch utilises VIC State Government's Regional/LGA projections released in 2023, adjusted employing a method of weighted aggregation of population growth from LGA to SA2 levels. Growth rates by age group are applied across all areas for years 2032 to 2041. Future trends predict exceptional growth, placing Rockbank in the top 10 percent of statistical areas nationally. The area is expected to expand by 10,364 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 146.7% in total over the 17 years.

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

AreaSearch analysis of ABS building approval numbers shows Rockbank recorded around 157 residential properties granted approval each year over the past five financial years ending FY25, totalling an estimated 785 homes. As of FY26106 approvals have been recorded. On average, 3.9 new residents per year are associated with every home built in Rockbank between FY21 and FY25. This results in demand significantly exceeding new supply, typically leading to price growth and increased buyer competition.

New properties are constructed at an average expected cost of $373,000. Additionally, $1.8 million in commercial approvals have been registered in this financial year, indicating the area's residential nature. Compared to Greater Melbourne, Rockbank records 174% more development activity per person, suggesting ample buyer choice, although construction activity has recently eased. This high level of activity reflects strong developer confidence in the area, with new building activity comprising 89% standalone homes and 11% medium and high-density housing, maintaining Rockbank's suburban identity suited to buyers seeking space. The location currently has approximately 36 people per dwelling approval, indicating an expanding market.

AreaSearch's latest quarterly estimate forecasts Rockbank will gain 7,942 residents by 2041. At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.

The area offers limited local employment opportunities, as indicated by the Census working population vs resident population count. Between December 2024 and December 2025, employment levels increased by 2.8%, labour force by 4.8%, leading to a 1.8 percentage point rise in unemployment. In comparison, Greater Melbourne recorded employment growth of 2.4% and labour force growth of 2.8%, with unemployment rising by 0.3 percentage points. 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 Rockbank's employment mix indicates local employment should increase by 6.5% over five years and 13.3% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not consider localized population projections.
