Gilmore

Household income in the 90.9th percentile nationally tells the opening story of Gilmore, a compact 2.05 km2 suburb in Canberra's south where public sector employment underpins the economy and 92.8% of dwellings are separate houses. With a population of 2,706 and a median age of 37 (3.0 years below national), Gilmore skews toward working-age families, with couples with children making up the largest household type. The suburb scores IRSAD decile 8, placing it in the upper advantage tier compared to most Australian communities, yet the median house price of $587,000 remains well below Canberra's inner-north equivalents, offering relative affordability within a high-income territory.

At $587,000, the median house price in Gilmore sits at a level that, combined with weekly household income of $2,416, produces a mortgage-to-income ratio of 19.6%, well below the 30% stress threshold. Monthly mortgage repayments average $2,048, manageable by ACT standards. The housing stock is strongly detached: 92.8% of dwellings are separate houses, and 45.5% have four or more bedrooms, compared to just 3.8% with two bedrooms. That bedroom profile reflects the family-oriented character, with 964 couples raising children in the suburb. Semi-detached dwellings account for the remaining 7.2%, and no apartments are recorded, so buyers seeking an ACT house without climbing into inner-suburb pricing will find Gilmore representative of value in the territory.

For Buyers

At $587,000, the median house price in Gilmore sits at a level that, combined with weekly household income of $2,416, produces a mortgage-to-income ratio of 19.6%, well below the 30% stress threshold.

For Investors

Gilmore's 23.2% renter share is lower than the national average, and weekly rent of $430 against a $587,000 median implies a gross yield near 3.8%, modest but not atypical for ACT. The vacancy rate of 2.8% signals balanced conditions rather than oversupply. Net internal migration runs at negative 33 residents per year while overseas arrivals add 12, keeping demand for rental stock steady without strong pressure on rents. Only 2 development applications were lodged in the past 12 months, indicating very limited new supply entering the area. The rent-to-income ratio of 17.8% keeps tenants financially comfortable, which supports stable tenancy and low arrears risk, but the suburb's population trend of negative 0.59% annually is a factor investors should weigh against yield prospects.

Demographics

Gilmore's median age of 37 is 3.0 years below the national figure, reflecting the concentration of working-age families rather than retirees.

Average household size of 2.8 is 0.3 above national, driven by the prevalence of couple-with-children families.

Transport to Work

Car dependency defines transport in Gilmore: 89.7% of residents drive to work, compared to just 2.7% using public transport and 1.5% walking or cycling. This is above the national car-dependency norm, reflecting the suburb's southern Canberra location and limited bus connectivity relative to inner suburbs. No schools are recorded within the suburb boundary in this dataset, so families rely on nearby institutions in adjacent Tuggeranong suburbs. SEIFA IRSAD decile 8 places Gilmore in the upper advantage tier nationally, indicating below-average disadvantage across social and economic dimensions. Housing stress metrics are low: rent-to-income at 17.8% and mortgage-to-income at 19.6% both sit comfortably below stress thresholds, and 6.1% of residents need daily assistance, reflecting some care needs consistent with the aging shift observed over the past decade.

Population Forecast

-0.59%/yr

(-16 people/yr)

Established

Gilmore's population has contracted slightly over the decade, down 4.8% from the 2011 base, with an annual trend of negative 0.59% or approximately 16 fewer residents per year. Medium forecasts project the population falling from roughly 2,647 in 2026 to around 2,568 by 2031 as the aging trajectory tightens. The senior share grew 7.6 points while the young adult share fell 1.8 points over the decade, typical of an aging-trajectory suburb. Net internal migration is negative at 33 residents per year, partly offset by 12 overseas arrivals annually. The gentrification score of 12 places Gilmore firmly in the not-gentrifying category, and with affordability already improving from 43.0% in 2011 to 36.9% in 2021, the suburb's relative value position is strengthening even as absolute population drifts lower.

Net internal migration is negative 33 residents per year and population is declining at 0.59% annually, so demand-side growth is limited.

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.
