Deagon

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

Based on analysis of ABS population updates for the broader area and new addresses validated by AreaSearch, as of February 2026, the estimated population of the suburb of Deagon is around 4,002. This reflects an increase of 229 people since the 2021 Census, which reported a population of 3,773 people in the suburb. The change was inferred from the resident population of 3,977 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 34 validated new addresses since the Census date. This level of population equates to a density ratio of 1,419 persons per square kilometer, above the average seen across national locations assessed by AreaSearch. The suburb's growth rate of 6.1% since the census positions it within 0.7 percentage points of the SA3 area (6.8%), demonstrating competitive growth fundamentals. Population growth for the area was primarily driven by interstate migration that contributed approximately 39.0% of overall population gains during recent periods, although all drivers including overseas migration and natural growth were positive factors.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with a base year of 2022. For any SA2 areas not covered by this data, and for years post-2032, Queensland State Government's SA2 area projections are adopted, released in 2023 and based on 2021 data. It should be noted that these state projections do not provide age category splits; hence where utilised, AreaSearch is applying proportional growth weightings in line with the ABS Greater Capital Region projections for each age cohort, released in 2023 based on 2022 data. Moving forward with demographic trends, a population increase just below the median of statistical areas analysed by AreaSearch is expected for the suburb of Deagon. The area is expected to grow by 177 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 3.8% in total over the 17 years.

Residential development activity is lower than average in Deagon according to AreaSearch's national comparison of local real estate markets

Deagon averaged approximately 19 new dwelling approvals annually. Between FY-21 and FY-25, around 99 homes were approved, with an additional 6 approved in FY-26 to date. Over the past five financial years, about 1.4 people moved to the area per dwelling built on average. However, this figure has increased to 4.3 people per dwelling over the past two financial years, suggesting growing popularity and potential undersupply.

The average expected construction cost value of new properties is $419,000, slightly above the regional average. In FY-26, there have been $1.4 million in commercial approvals. Relative to Greater Brisbane, Deagon records 68.0% more development activity per person. New construction has consisted entirely of detached houses, maintaining the area's low-density suburban character with a focus on family homes.

The latest AreaSearch quarterly estimate projects Deagon's population to grow by 152 residents through to 2041. Based on current development patterns, new housing supply should meet demand, offering good conditions for buyers and potentially facilitating further population growth.

Employment conditions in Deagon remain below the national average according to AreaSearch analysis

Deagon's workforce is skilled with notable representation in essential services sectors. The unemployment rate was 5.8% as of an unspecified past year. Employment growth over the same period was estimated at 12.0%.

As of September 2025, 2,276 residents were employed while the unemployment rate stood at 1.8%, higher than Greater Brisbane's 4.0%. Workforce participation was 72.8%, slightly above Greater Brisbane's 70.7%. According to Census responses, 21.1% of residents worked from home.

Construction had particularly high representation at 1.3 times the regional average. Conversely, professional & technical services showed lower representation at 7.4%. The area appears to offer limited local employment opportunities based on Census data comparing working population to resident population. Over a 12-month period ending in an unspecified date, employment increased by 12.0% and labour force grew by 10.7%, leading to a 1.0 percentage point decrease in unemployment rate. In comparison, Greater Brisbane recorded employment growth of 3.8%, labour force growth of 3.3%, with unemployment falling 0.5 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 project overall employment expansion by 6.6% over five years and 13.7% over ten years. Applying these projections to Deagon's employment mix suggests local employment should increase by 6.5% over five years and 13.5% over ten years, based on a simple weighting extrapolation for illustrative purposes.
