Zilzie

Zilzie lies within the top quartile of areas nationally for population growth performance according to AreaSearch analysis of recent, and medium to long-term trends

Based on analysis of ABS population updates for the broader area, the estimated population of Zilzie as of Feb 2026 is around 3,103. This reflects an increase of 257 people since the 2021 Census, which reported a population of 2,846 people. The change is inferred from the resident population of 2,937 estimated by AreaSearch following examination of the latest ERP data release by the ABS (June 2024) and an additional 16 validated new addresses since the Census date. This level of population equates to a density ratio of 321 persons per square kilometer. Zilzie's 9.0% growth since the 2021 census exceeded the SA4 region (6.8%) and the SA3 area, marking it as a growth leader in the region. Population growth for the area was primarily driven by interstate migration that contributed approximately 91.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered and years post-2032, Queensland State Government's SA2 area projections released in 2023 based on 2021 data are adopted. It should be noted that these state projections do not provide age category splits; hence proportional growth weightings in line with the ABS Greater Capital Region projections released in 2023 based on 2022 data are applied where utilised. Looking at population projections moving forward, a significant population increase in the top quartile of locations outside of capital cities is forecast for Zilzie, expected to grow by 973 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 30.4% in total over the 17 years.

Recent residential development output has been above average within Zilzie when compared nationally

AreaSearch analysis of ABS building approval numbers shows Zilzie recorded approximately 17 residential properties granted approval annually. Over the past five financial years, from FY21 to FY25, around 88 homes were approved, with a further six approved in FY26 so far. Each dwelling built over these years resulted in an average of 2.5 new residents per year.

The average construction cost value for new homes was $438,000. This financial year, commercial approvals totalled $527,000, indicating minimal commercial development activity compared to residential. Zilzie's development activity is 56.0% higher than the Rest of Qld when measured per person. New developments consist of 81.0% detached dwellings and 19.0% attached dwellings, maintaining the area's low density character focused on family homes.

With around 124 people per approval, Zilzie reflects a developing area. By 2041, AreaSearch estimates Zilzie will grow by 944 residents. At current development rates, housing supply may struggle to match population growth, potentially increasing buyer competition and supporting price increases.

Zilzie shows employment indicators that trail behind approximately 70% of regions assessed across Australia

Zilzie's workforce is balanced across white and blue-collar jobs with prominent essential services sectors. The unemployment rate was 4.3% in the past year, showing an estimated employment growth of 0.7%. As of September 2025, 1,362 residents were employed, with an unemployment rate at 4.3%, 0.2% higher than Rest of Qld's rate of 4.1%.

Workforce participation was lower, at 61.0% compared to Rest of Qld's 65.7%. Census data indicated that 6.3% of residents worked from home, potentially influenced by Covid-19 lockdowns. Employment is concentrated in health care & social assistance, mining, and construction. Mining has a significant presence, with an employment share 3.5 times the regional level, while agriculture, forestry & fishing is under-represented at 1.7% compared to Rest of Qld's 4.5%.

Limited local employment opportunities are suggested by the discrepancy between working population and resident population counts. Over a 12-month period, employment increased by 0.7%, labour force by 1.5%, leading to an unemployment rise of 0.8 percentage points. In comparison, Rest of Qld recorded higher growth rates for employment (1.7%) and labour force (2.1%), with a smaller increase in unemployment (0.3 percentage points). National employment forecasts from Jobs and Skills Australia, issued in May-25, project national employment to expand by 6.6% over five years and 13.7% over ten years. Applying these projections to Zilzie's employment mix suggests local employment should increase by 6.1% over five years and 13.1% over ten years, though these are simple extrapolations for illustrative purposes only.
