Glossodia
At 33 years, Glossodia's median age sits 7 years below the national figure, making it one of the younger owner-occupier belts in the Hawkesbury region. Household income lands in the 80.1st percentile nationally, yet 98.9% of dwellings are separate houses on land large enough to keep density at just 184 people per km2. Construction employs 21.8% of the workforce, well above average, which partly explains the high 54.5% mortgage rate. The suburb spans 15.54 km2 with 2,865 residents who are stable, with 80.9% having lived there at least 5 years.

2024-2025 (PSI derived)
The median house price sits at $925,000, with the most recent data point reaching $1,000,000 in 2025, a 12.4% rise from $889,500 in 2024. With 98.9% of dwellings being separate houses and apartments at just 0.7%, buyers are almost exclusively competing for detached stock. Bedrooms skew large: 43.3% of homes have 4 or more bedrooms and 50.9% have 3, so the typical purchase is a family home rather than a starter flat. Monthly mortgage repayments average $2,067 and the mortgage-to-income ratio is 22.5%, below the 30% stress threshold, making ownership more comfortable here than in many other suburbs at similar price points. Outright owners account for 29.2% of households, a meaningful base that reduces churn.

Outright owners account for 29.2% of households, a meaningful base that reduces churn.
For Investors
Renters represent only 16.3% of households, lower than the national average, so the tenant pool is thin by design. Weekly rent averages $430, which against the $925,000 median implies a gross yield below 2.5%, modest but consistent with a lifestyle suburb rather than a high-turnover rental market. The vacancy rate stands at 4.0%, above the tight sub-2% thresholds seen in many Sydney fringe markets, suggesting some softness in rental demand. Development activity shows 20 applications in the past 12 months, mostly individual house and subdivision works, indicating incremental rather than volume-driven supply. The 12.4% annual price growth recorded between 2024 and 2025 is the primary investment argument, though the shallow renter base means returns depend on capital appreciation rather than yield.

Tenure
Glossodia is almost entirely a detached-house suburb. Separate houses account for 98.9% of dwellings, with semi-detached at 0.4% and apartments just 0.7%, a profile that restricts density and keeps land values elevated. The size skew is pronounced: 43.3% of homes have 4 or more bedrooms and 50.9% have 3 bedrooms, meaning nearly all stock suits families. Prices rose from $889,500 in 2024 to $1,000,000 in 2025, a 12.4% increase over one year. Tenure splits into roughly three layers: 29.2% own outright, 54.5% carry a mortgage, and only 16.3% rent, a ratio that puts mortgage holders in a clear majority compared to national norms. Mortgage-to-income at 22.5% and rent-to-income at 20.3% both sit below stress thresholds, suggesting households are managing repayments comfortably.

Transport to Work
Car dependency is extreme here, with 92.9% of commuters driving, above the national average, because public transport access in the Hawkesbury region is limited. Walking and cycling account for just 2.9% of journeys. The suburb spans 15.54 km2 at low density (184 residents per km2), providing space per household well above the state average. Rent stress is absent, with rent-to-income at 20.3% and mortgage-to-income at 22.5%, both below the 30% stress threshold. Only 4.1% of residents (111 people) need daily assistance, and the volunteering rate is 13.6%. No schools are recorded within the suburb boundary, so families rely on nearby Hawkesbury towns for schooling, a practical trade-off for the large-lot, low-density lifestyle. Crime data is not available for Glossodia in this dataset.

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.
