Coominya
With only 1,029 residents spread across 114.71 square kilometres, Coominya is one of the more thinly settled localities in the Lockyer Valley, averaging just 9 people per square kilometre compared to urban norms many times higher. What stands out is the median age of 50, a full 10 years above the national figure, and the fact that every single dwelling recorded is a separate house, giving it 100% detached housing stock. Household income sits at the 27th percentile nationally, reflecting the rural character and lower-wage employment base, yet housing costs are modest enough that neither mortgage nor rent stress thresholds are breached.

Estimated from rent (2025)
The estimated median house price of $332,000 makes Coominya considerably more affordable than the national median, which is a direct consequence of its rural location and small population base. Monthly mortgage repayments average $1,274, and the mortgage-to-income ratio of 23.9% sits comfortably below the 30% stress threshold, meaning buyers here are not financially stretched relative to their income. All dwellings are separate houses, with three-bedroom homes the most common at 49.9% and four-plus bedroom homes at 32.3%, skewing toward larger rural properties. Outright ownership is high at 42.7%, slightly ahead of the 42.5% on mortgages, suggesting a stable, long-resident base rather than a market driven by recent entrants.

For Investors
Rental demand in Coominya is thin: only 14.8% of dwellings are rented, well below typical urban rental markets, and the vacancy rate of 16.8% signals that a significant share of rental stock sits unoccupied. Weekly rent averages $250, a low figure even for regional Queensland, and the rent-to-income ratio of 20.3% keeps tenants comfortable but constrains gross yields against the $332,000 estimated median. Development activity is low, with just 9 applications in the past 12 months, mostly shed construction and plumbing works rather than new dwellings. Population is small and aging, with a median age 10 years above the national average, limiting the organic demand growth that drives rental markets in higher-trajectory areas.

Demographics
The median age of 50 is 10 years above the national figure, placing Coominya firmly in the aging-resident category. Overseas-born residents make up 14.2% of the population, which is 7.4 percentage points below the national average, consistent with the predominantly Anglo-Celtic ancestry profile: English (436 people), Irish (123), Scottish (104) and German (74) are the leading ancestries. University qualifications reach only 16.0%, which is 14.1 percentage points below the national figure, reflecting the agricultural and trade-oriented employment base. Average household size of 2.5 matches the national figure exactly. Couples without children at 33.8% of families and couples with children at a smaller share point to a maturing population where children have left home.

Tenure
Every recorded dwelling in Coominya is a separate house, a 100% detached rate that reflects its rural character. The tenure split is almost even between outright owners (42.7%) and mortgage holders (42.5%), with renters a small minority at 14.8%, lower than typical state and national rates. Three-bedroom homes account for 49.9% of dwellings, with four-plus bedrooms adding another 32.3%, meaning over 80% of homes have at least three bedrooms. The estimated median house price of $332,000 is based on 2025 rental data and sits well below the Queensland state median, making entry affordable on paper. The vacancy rate of 16.8% is elevated, indicating not all housing stock is actively occupied, which can suppress price growth in a small market.

Economy & Employment
Healthcare is the dominant employing sector at 18.9% of workers (37 people), followed by Education at 13.3% (26) and Agriculture at 12.8% (25). The agricultural share reflects the rural land use across Coominya's 114.71 square kilometres. By occupation, Managers and Labourers are tied at 75 workers each, the top two categories, a split that captures both the owner-operator farming character and the manual labour demand in the area. The unemployment rate is 10.4%, above the national average, and the participation rate is low at 42.7%, with 443 residents not in the labour force, largely explained by the older median age. Household income at the 27th percentile nationally confirms that wages here run below average for Australia.

Transport to Work
Car dependence in Coominya is near absolute: 89.1% of residents drive to work, higher than the national average, which is expected for a settlement with 9 people per square kilometre and no recorded public transport use. Walking and cycling account for 2.7% of commutes, likely short local trips. No schools are recorded inside the Coominya boundary in this dataset, so families rely on facilities in nearby Fernvale or Ipswich. Crime statistics are not available for this locality. The volunteering rate of 10.7% is modest but reflects community participation in a small rural setting. Housing stress is contained: rent-to-income at 20.3% and mortgage-to-income at 23.9% both sit below standard stress thresholds, and assistance needs at 12.9% of residents are higher than urban norms, consistent with the older age profile.

Frequently Asked Questions
Is Coominya a good suburb to live in?
Coominya suits buyers seeking rural lifestyle on a budget: the estimated median house price is $332,000 and the mortgage-to-income ratio of 23.9% stays below the 30% stress threshold. The trade-offs are limited services, no recorded schools within the locality, a low participation rate of 42.7% and a median age of 50, which is 10 years above the national figure.
What is the median house price in Coominya?
The estimated median house price is $332,000, based on 2025 rental data. Weekly rent averages $250 and monthly mortgage repayments run approximately $1,274, giving a mortgage-to-income ratio of 23.9%, which is below the 30% financial stress threshold.
What schools are in Coominya?
No schools are recorded inside the Coominya boundary in this dataset. Families typically access schools in nearby Fernvale or further afield in Ipswich. The locality's 16.0% university qualification rate is 14.1 percentage points below the national figure, reflecting the trade and agricultural employment base.
Is Coominya safe?
Detailed crime statistics are not available for Coominya in this dataset. As a proxy, 12.9% of the 1,029 residents need daily assistance, higher than urban norms, which reflects the older median age of 50 rather than elevated crime. The low-density rural setting of 9 people per square kilometre is typically associated with lower crime exposure than urban areas.
Is Coominya good for property investment?
The investment case is cautious. The vacancy rate of 16.8% is high, meaning a significant share of rental properties sit empty. Only 14.8% of dwellings are rented, limiting the tenant pool. Weekly rent of $250 against an estimated median of $332,000 implies a modest gross yield. The aging demographic and minimal development pipeline (9 applications in 12 months) suggest limited capital growth drivers compared to higher-growth Queensland markets.
How is Coominya's population changing?
No formal forecast is available for Coominya, but the Census profile points to a stable to declining trajectory. The median age of 50 is 10 years above the national average, 80.2% of residents stayed at the same address over 5 years, and the participation rate of 42.7% is low. These signals are consistent with a rural locality where working-age residents move out and older, established households remain.
How to read these comparisons
Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.
Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.
Data sources: ABS 2021 Census (demographics, income, tenure), state Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
