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

As of November 2025, the estimated population of Zilzie is around 2,916 people. This figure reflects a growth of 70 individuals since the 2021 Census, which reported a population of 2,846. The increase is inferred from AreaSearch's estimation of the resident population at 2,878 as per June 2024 ERP data release by ABS and an additional 14 validated new addresses since the Census date. This results in a density ratio of 301 persons per square kilometer. Over the past decade, Zilzie has shown resilient growth with a compound annual growth rate of 1.6%, outperforming its SA3 area. Interstate migration contributed approximately 91.0% of overall population gains during recent periods.

For projections, AreaSearch uses ABS/Geoscience Australia data 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 from 2023 based on 2021 data are adopted. It is noted that these state projections lack age category splits, thus AreaSearch applies proportional growth weightings aligned with ABS Greater Capital Region projections released in 2023 based on 2022 data for each age cohort. By 2041, the suburb of Zilzie is projected to grow by 984 persons, reflecting a total increase of 38.9% over the 17-year period.

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

AreaSearch analysis of ABS building approval numbers shows Zilzie recorded approximately 13 residential properties granted approval annually. Over the past five financial years, from FY21 to FY25, around 65 homes were approved, with one more in FY26 so far. On average, 3.4 people moved to the area each year for every dwelling built during this period.

This indicates supply is lagging demand, likely leading to heightened buyer competition and pricing pressures. New properties are constructed at an average expected cost of $438,000, which is below the regional average, suggesting more affordable housing options. In FY26, $2.2 million in commercial development approvals have been recorded, indicating a predominantly residential focus.

Compared to the Rest of Qld, Zilzie has somewhat elevated construction activity, with 16.0% above the regional average per person over the past five years. This maintains good buyer choice while supporting existing property values. However, building activity has slowed in recent years. New development consists mostly of detached dwellings (82.0%) and a smaller portion of medium and high-density housing (18.0%), preserving the area's low density nature and attracting space-seeking buyers. The estimated population per dwelling approval is 467 people. Looking ahead, Zilzie is projected to grow by 1,135 residents through to 2041, according to AreaSearch's latest quarterly estimate. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing buyer competition and supporting stronger price growth.

Mining had notably high concentration with employment levels at 3.5 times the regional average. Agriculture, forestry & fishing was under-represented at 1.7% compared to Rest of Qld's 4.5%. The area appeared to offer limited local employment opportunities based on Census data. Over the 12 months to June 2025, employment increased by 4.2%, while labour force grew by 5.4%, causing unemployment to rise by 1.2 percentage points. Rest of Qld recorded employment growth of 1.8% and unemployment rose by 0.2 percentage points during the same period. Jobs and Skills Australia's national employment forecasts from Sep-22 projected national employment growth at 6.6% over five years and 13.7% over ten years. Applying these projections to Zilzie's employment mix suggested local employment should increase by 6.1% over five years and 13.1% over ten years, based on a simple weighting extrapolation for illustrative purposes.
