Griffin suits buyers who value family-sized space and newer-style housing over apartment living. Four or more bedrooms account for 60.6% of dwellings, compared with 34.7% for three-bedroom homes, while 72.4% are separate houses and 26.7% are semi-detached. The typical monthly mortgage figure is 1,941, and mortgage costs represent 22.3% of household income, above the 19.1% rent-to-income share. That difference matters because larger homes require more borrowing even when household incomes rank at the 75.4th percentile. With 39.7% of households already paying a mortgage and 53.9% renting, buyers should compare recent sales by land size, bedroom count and dwelling type rather than relying on a single suburb-wide figure.

For Investors
Griffin has a substantial rental base, with 53.9% of households renting compared with only 5.8% owning outright. Weekly rent is 385 and the vacancy rate is 3.9%, while rent growth has reached 8.6%, giving landlords a reasonable demand backdrop. Internal migration is the primary growth driver, and the annual forecast trend is 3.7%, which can support tenant demand as new households enter the area. Fifteen development matters were recorded over 12 months, so investors should check whether nearby construction adds competing stock or improves local amenity. The 72.4% separate-house share may appeal to families, but yield should be tested against the verified purchase price because a current median house price is not available.

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.
