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 ABS population updates and AreaSearch validation, Deagon's estimated population is around 4,034 as of May 2026. This reflects an increase of 261 people since the 2021 Census, which reported a population of 3,773. The growth is inferred from AreaSearch's estimation following examination of ABS's latest ERP data release in June 2025 and additional validated new addresses since the Census date. This level of population equates to a density ratio of 1,430 persons per square kilometer, above average national levels assessed by AreaSearch. Deagon's growth rate of 6.9% since census positions it close to the SA3 area's growth rate of 7.7%. Population growth was primarily driven by interstate migration contributing approximately 39.0% during recent periods.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered or years post-2032, Queensland State Government's SA2 area projections released in 2023 based on 2021 data are adopted. These state projections lack age category splits; hence proportional growth weightings aligned with ABS Greater Capital Region projections (released in 2023, based on 2022 data) are applied when utilised. Demographic trends suggest lower quartile growth for statistical areas nationally, with Deagon expected to grow by 147 persons to 2041, reflecting a total increase of 3.6% over the 16 years.

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

AreaSearch analysis indicates Deagon averaged around 19 new dwelling approvals annually. Between FY-21 and FY-25, approximately 99 homes were approved, with another 9 in FY-26 so far. Over the past five financial years, an average of 1.5 people moved to the area per dwelling built, suggesting balanced supply and demand. However, this figure has increased to 4.4 people per dwelling over the last two financial years, indicating growing popularity and potential undersupply.

New properties are constructed at an average expected cost of $419,000, slightly above the regional average. This year, there have been $1.4 million in commercial approvals, predominantly focused on residential development. Compared to Greater Brisbane, Deagon records 69.0% more development activity per person, offering buyers greater choice. Recent development has consisted entirely of detached houses, maintaining the area's suburban identity with a concentration of family homes suited for space-seeking buyers.

With around 246 people per dwelling approval, Deagon exhibits a developing market. By 2041, population forecasts suggest Deagon will gain 147 residents. Current construction levels should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.

Deagon has very high levels of nearby infrastructure activity, ranking in the top 10% nationally

Construction had notably high representation with employment levels at 1.3 times the regional average.

Conversely, professional & technical services showed lower representation at 7.4% compared to the regional average of 8.9%. The area appears to offer limited local employment opportunities based on Census data comparing working population and resident population. Over a 12-month period ending in May-25, employment increased by 10.8% while labour force grew by 9.8%, leading to a fall in unemployment rate of 0.9 percentage points. In comparison, Greater Brisbane saw employment grow by 3.2%, labour force expand by 3.0%, and unemployment fall by 0.1 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 suggest potential future demand within Deagon. Applying these projections to Deagon's employment mix indicates local employment should increase by 6.5% over five years and 13.5% over ten years, assuming no changes in population projections.
