Gledswood Hills
A 96.0th-percentile household income profile sits alongside a median age of 31, making Gledswood Hills notably younger than the national median by 9 years. Housing is overwhelmingly detached, with 97.6% separate houses and 87.4% containing four or more bedrooms, matching the 3.3-person average household size and 62.9% share of couples with children. The suburb has 6,112 residents and a 6.18% annual high-growth trend, driven by internal migration. Compared with nearby Gregory Hills and Harrington Park, Gledswood Hills reads as a larger-home, family-oriented market, although its 23.0% renter share still creates a meaningful tenant base.

Homebuyers are looking at a strongly detached, family-sized housing base: 97.6% of dwellings are separate houses, 87.4% have four or more bedrooms and only 0.2% are apartments. That layout suits the average 3.3-person household and the 62.9% of families who are couples with children, but it also points to larger purchase and upkeep commitments than a compact unit market. A monthly mortgage benchmark of $2,730 represents 22.7% of household income, while rent equals 19.4%, so mortgage stress is not flagged. Household income ranks at the 96th percentile nationally, higher than the national distribution. Compared with nearby Gregory Hills and Harrington Park, assess land size, build quality and commuting costs carefully.

For Investors
Investors have a tenant market of 23.0% renting, with weekly rent at $540 and vacancy at 2.4%. The renter share is below the 66.6% mortgage share, so demand is shaped more by family households and local employment than by a large apartment population. The 97.6% separate-house mix and 87.4% four-plus-bedroom share can suit longer-stay tenants, but they also bring higher maintenance and price exposure than smaller dwellings. Development activity is substantial at 193 records across 12 months, creating ongoing supply and competition between newer and established homes. The wider growth setting is high growth at 6.18% annually, with internal migration the primary driver. Compared with a lower-growth suburb, monitor leasing depth and resale competition rather than assuming automatic price gains.

Demographics
Gledswood Hills has a median age of 31, which is 9 years below the national median, and an average household size of 3.3, 0.8 above the national figure. Family formation is central: couples with children account for 62.9% of families, while one-parent families represent 8.8%. University attainment is 39.8%, 9.7 percentage points above the national comparison, supporting a sizeable professional and administrative workforce. The largest recorded ancestries are Other (1,546), English (1,193), Italian (616), Indian (422) and Scottish (301). Arabic (118), Hindi (82), Urdu (60), Italian (49) and Serbian (42) are the leading listed languages. Compared with nearby Gregory Hills and Harrington Park, the suburb's younger, larger-household profile helps explain demand for schools, four-plus-bedroom homes and family services. A 71.6% stay rate also indicates resident continuity, while 28.4% turnover keeps new arrivals visible.

Tenure
Housing is a concentrated detached-house market rather than an apartment precinct. Separate houses account for 97.6% of dwellings, compared with 0.2% apartments and 2.3% semi-detached homes; 87.4% of homes have four or more bedrooms, versus 9.8% with three bedrooms. Tenure is mortgage-led, with 66.6% paying a mortgage, 10.1% owning outright and 23.0% renting. That pattern follows the 3.3-person average household size and 62.9% couples-with-children share, because larger households need more floor area. The monthly mortgage benchmark is $2,730 and weekly rent is $540, with mortgage-to-income at 22.7% and rent-to-income at 19.4%, so neither stress flag is triggered. Compared with nearby Gregory Hills and Harrington Park, buyers should assess land, dwelling age and future supply because the detached format can create a wider gap between homes than in unit-heavy markets.

Economy & Employment
The employment base combines essential services with construction and professional work. Healthcare leads at 16.4% of industry employment (363 people), followed by Construction at 12.0% (266), Education at 11.5% (256), Public Administration at 10.6% (235) and Professional/Technical at 7.1% (158). Occupations are led by Professionals (774), Clerical/Admin (522), Managers (479), Trades (404) and Community/Personal (296). Participation is 75.7%, full-time employment is 63.4% and unemployment is 3.9%, while 41.1% work from home. Socioeconomic measures are strong but not uniform: IER reaches decile 10, above IEO decile 7, while IRSD is decile 8 and IRSAD decile 9. That gap suggests economic resources rank higher than education and occupation measures, consistent with household income at the 96th percentile. The mix supports local spending, although commuting remains relevant for the 53.2% who drive.

Transport to Work
Daily life is strongly car-oriented: 53.2% drive to work, compared with 2.4% using public transport and 0.8% walking or cycling. Work-from-home participation is high at 41.1%, which can reduce weekday travel for some households but makes home office space more valuable in the 87.4% four-plus-bedroom housing market. Two local government schools provide a primary and secondary option, giving families access to both school stages within the suburb; enrolment zones should still be checked against the exact address. Socioeconomic amenity is supported by an IRSAD decile of 9 and an IRSD decile of 8, with IRSAD higher than IRSD. Check current police information and street-level conditions before deciding. Compared with a transit-led area, expect more planning around school runs, shopping and commuting.

High GrowthGledswood Hills sits in a high-growth setting, with the trend forecast at 6.18% annually and internal migration identified as the primary driver. The absence of a COVID dip points to continuity rather than a rebound-only pattern. Development activity adds to that momentum, with 193 records across 12 months, although new supply can increase competition between established and recently completed homes. Compared with a stable-growth suburb, the combination of 6.18% annual growth, internal migration and high development activity calls for buyers and investors to track infrastructure, construction timing and resale supply. The current population is 6,112, giving the suburb a substantial local base for this ongoing change.

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 education open registers (school locations), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
