Tyabb

An assessment of population growth drivers in Tyabb reveals an overall ranking slightly below national averages considering recent, and medium term trends

Based on analysis of ABS population updates for Tyabb, as of Nov 2025 its population is estimated at around 3806. This reflects an increase of 357 people since the 2021 Census, which reported a population of 3449 people. The change is inferred from the resident population of 3749, estimated by AreaSearch following examination of the latest ERP data release by the ABS (June 2024), and an additional 40 validated new addresses since the Census date. This level of population equates to a density ratio of 161 persons per square kilometer. Tyabb's growth of 10.4% since the 2021 census exceeded the SA3 area (2.3%) and the SA4 region, marking it as a growth leader in the region. Population growth for the suburb was primarily driven by natural growth that contributed approximately 52.0% 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. 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. Looking at population projections moving forward, a population increase just below the median of Australian statistical areas is expected, with the suburb expected to expand by 395 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 2.9% in total over the 17 years.

AreaSearch assessment of residential development drivers sees a low level of activity in Tyabb, placing the area among the bottom 25% of areas assessed nationally

AreaSearch analysis of ABS building approval numbers shows Tyabb had approximately 14 new homes approved annually over the past five financial years, totalling around 74 homes. In FY26 so far, there have been three approvals. The population decline in recent years suggests that new supply has likely kept pace with demand, offering buyers good choices while new homes are being built at an average expected construction cost of $502,000. This financial year has seen $942,000 in commercial approvals, indicating a predominantly residential focus.

Compared to Greater Melbourne, Tyabb records 19.0% less building activity per person and ranks among the 50th percentile nationally. New development consists of 71.0% detached houses and 29.0% townhouses or apartments, preserving the area's low density nature with an emphasis on detached housing attracting space-seeking buyers. This marks a significant shift from existing housing patterns, which are currently 90.0% houses, suggesting diminishing developable land availability and responding to evolving lifestyle preferences and housing affordability needs. With around 319 people per dwelling approval, Tyabb indicates a developing market.

Population forecasts suggest Tyabb will gain 111 residents by 2041 based on the latest AreaSearch quarterly estimate. Given current development patterns, new housing supply should readily meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.

AreaSearch analysis indicates Tyabb maintains employment conditions that align with national benchmarks

Tyabb has a diverse workforce with balanced white and blue collar jobs. The construction sector is prominent with an unemployment rate of 4.5% and estimated employment growth of 3.6% in the past year (AreaSearch data).

As of June 2025, 1,975 residents are employed while the unemployment rate is 0.2% lower than Greater Melbourne's rate of 4.6%. Workforce participation stands at 66.9%, slightly higher than Greater Melbourne's 64.1%. Key industries include construction, health care & social assistance, and retail trade. Notably, construction employment is 1.9 times the regional average.

Conversely, professional & technical services have limited presence with only 4.4% of jobs compared to the regional 10.1%. Many Tyabb residents commute elsewhere for work, indicating local employment opportunities may not fully meet demand. Between June 2024 and June 2025, employment levels increased by 3.6% while labour force grew by 4.8%, causing unemployment to rise by 1.1 percentage points (AreaSearch analysis). Jobs and Skills Australia's national employment forecasts from Sep-22 project overall growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Tyabb's employment mix suggests local jobs should increase by 6.2% in five years and 12.9% in ten years, though this is a simplified extrapolation for illustrative purposes only.
