Collaroy Plateau

Collaroy Plateau is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

As of November 2025, the estimated population of Collaroy Plateau is around 4,871, reflecting an increase of 66 people since the 2021 Census which reported a population of 4,805. This growth was inferred from AreaSearch's estimation of the resident population at 4,851 based on ABS ERP data released in June 2024 and additional validated new addresses since the Census date. The suburb's population density is 3,992 persons per square kilometer, placing it in the top 10% nationally according to AreaSearch. Collaroy Plateau's growth rate of 1.4% since census is within 1.8 percentage points of its SA4 region (3.2%), indicating strong growth fundamentals. Overseas migration contributed approximately 77.0% of overall population gains during recent periods. For projections until 2041, AreaSearch uses ABS/Geoscience Australia data released in 2024 with a base year of 2022 for covered areas and NSW State Government's SA2 level projections released in 2022 with a base year of 2021 for uncovered areas.

These projections indicate an overall population decline by 299 persons by 2041, but growth is expected within specific age cohorts led by the 75 to 84 age group projected to grow by 152 people.

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

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, indicates Collaroy Plateau averaged around 11 new dwelling approvals per year. Between FY-21 and FY-25, approximately 57 homes were approved, with one additional approval in FY-26 to date. Population decline over recent years suggests new supply has likely been keeping up with demand, offering buyers good choice.

New properties are constructed at an average value of $1,197,000, indicating developers focus on the premium market with high-end developments. This financial year, there have been $322,000 in commercial approvals, demonstrating the area's residential nature. Compared to Greater Sydney, Collaroy Plateau shows approximately 75% of the construction activity per person. Nationally, it places among the 53rd percentile of areas assessed, though construction activity has intensified recently. This reflects market maturity and possible development constraints. New development consists of 40.0% detached dwellings and 60.0% attached dwellings, marking a significant departure from existing housing patterns (currently 94.0% houses).

This trend toward denser development provides accessible entry options appealing to downsizers, investors, and entry-level buyers. At around 301 people per approval, Collaroy Plateau reflects a low density area. With population expected to remain stable or decline, the area should see reduced pressure on housing, potentially creating opportunities for buyers.

Conversely, transport, postal & warehousing employs only 3.0% of local workers, which is lower than Greater Sydney's 5.3%.

Between June 2024 and June 2025, the labour force in Collaroy Plateau decreased by 0.1%, while employment decreased by 1.0%, leading to an increase in unemployment rate by 0.8 percentage points. This contrasts with Greater Sydney, where employment rose by 2.6% during the same period. Jobs and Skills Australia's national employment forecasts from Sep-22 offer insights into potential future demand within Collaroy Plateau. These projections suggest that national employment will expand by 6.6% over five years and 13.7% over ten years. However, growth rates vary significantly between industry sectors. Applying these industry-specific projections to Collaroy Plateau's employment mix indicates that local employment is expected to increase by 6.9% over five years and 13.9% over ten years, though it should be noted that this is a simple weighting extrapolation for illustrative purposes and does not account for localised population projections.
