Deagon

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

Deagon's 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 people. The change is inferred from the estimated resident population of 4,034 from the ABS as of June 2025 and an additional 37 validated new addresses since the Census date. This level of population equates to a density ratio of 1,430 persons per square kilometer. Deagon's growth rate of 6.9% since census positions it within 0.8 percentage points of the SA3 area (7.7%). Population growth was primarily driven by interstate migration contributing approximately 53.2%.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered and years post-2032, Queensland State Government's SA2 area projections are adopted, released in 2023 based on 2021 data. These state projections do not provide age category splits; hence proportional growth weightings are applied in line with ABS Greater Capital Region projections for each age cohort. Based on demographic trends and latest annual ERP population numbers, Deagon is expected to grow by 150 persons to 2041, reflecting a gain of 3.7% over the 16 years.

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

Deagon has seen approximately 19 new homes approved annually. Over the past five financial years, from FY21 to FY25, around 99 homes were approved, with an additional 9 approved so far in FY26. On average, about 1.4 people moved to the area for each dwelling built over these five years, indicating balanced supply and demand conditions. 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 homes is $327,000. This year, $1.4 million in commercial development approvals have been recorded, reflecting the area's residential nature. Compared to Greater Brisbane, Deagon has 69.0% more building activity per person, offering buyers greater choice. However, building activity has slowed in recent years, with all current activity consisting of detached dwellings, maintaining the area's suburban character focused on family homes.

With around 247 people per dwelling approval, Deagon shows a developing market. By 2041, it is projected that Deagon will gain approximately 150 residents based on recent AreaSearch quarterly estimates. Given current development patterns, new housing supply should meet demand, providing good conditions for buyers and potentially facilitating population growth beyond current projections.
