Seaforth - Calen

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

Seaforth-Calen's population is around 9,270 as of Feb 2026. This reflects an increase of 1,089 people since the 2021 Census, which reported a population of 8,181 people. The change was inferred from the estimated resident population of 8,657 in June 2024 and an additional 312 validated new addresses since the Census date. This level of population equates to a density ratio of 4.4 persons per square kilometer. Seaforth-Calen's growth rate of 13.3% since the 2021 census exceeded both the SA3 area (7.1%) and the SA4 region, marking it as a growth leader in the region. Population growth was primarily driven by interstate migration contributing approximately 66.0% of overall population gains during recent periods.

AreaSearch is adopting 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 released in 2023 based on 2021 data are adopted. These state projections do not provide age category splits, hence AreaSearch applies proportional growth weightings in line with ABS Greater Capital Region projections released in 2023 based on 2022 data for each age cohort. Considering projected demographic shifts, a population increase just below the median of regional areas nationally is expected by 2041. The area is expected to expand by 981 persons by 2041, reflecting an increase of 4.0% in total over the 17 years based on the latest annual ERP population numbers.

Recent residential development output has been above average within Seaforth - Calen when compared nationally

Seaforth - Calen has averaged approximately 32 new dwelling approvals annually over the past five financial years, from FY-21 to FY-25, with a total of 163 homes approved during this period. In FY-26, up to May, there have been 25 dwellings approved. Each year, an average of 3.5 people have moved to the area for each dwelling built over these five years, indicating that demand significantly outstrips supply.

This imbalance typically exerts upward pressure on property prices and intensifies competition among buyers. The average construction cost value of new properties is $395,000. In FY-26 up to May, commercial development approvals have reached $3.5 million, suggesting limited focus on commercial development in the area.

Compared to the rest of Queensland, Seaforth - Calen exhibits similar construction activity per capita, contributing to market stability that aligns with regional trends. However, construction activity has recently shown signs of easing. All new constructions in the area since FY-21 have been detached houses, preserving its traditional low-density character and appealing to families seeking spacious homes. With approximately 332 people being added to the population for each dwelling approval, Seaforth - Calen reflects a market in transition. According to AreaSearch's latest quarterly estimate, the area is projected to gain 368 residents by 2041. If current construction levels are maintained, housing supply should meet demand adequately, creating favorable conditions for buyers and potentially enabling growth that exceeds current forecasts.
