The $2,700,000 median house price places Netherby among Adelaide's most expensive markets. Prices rose 8% from $2,500,000 in the year to 1Q 2026, suggesting steady demand rather than speculative pressure. Separate houses make up 66.4% of dwellings, and 45.3% have four or more bedrooms, reflecting large family homes on sizeable blocks. Monthly mortgage repayments average $2,383, and the mortgage-to-income ratio of 21.7% sits comfortably below the 30% stress threshold, a sign that buyers at this level are well-resourced. Outright owners at 48.1% substantially outnumber mortgage holders at 35.6%, pointing to an established owner base rather than a market driven by recent leveraged buyers.

Outright owners at 48.1% substantially outnumber mortgage holders at 35.6%, pointing to an established owner base rather than a market driven by recent leveraged buyers.
For Investors
With only 16.3% of residents renting, the landlord pool is thin by comparison to broader Adelaide. Weekly rent of $380 against a $2,700,000 median implies a gross yield well below 1%, making yield-focused investment difficult to justify. The vacancy rate of 3.8% is moderate rather than tight, and 13 development applications in the past 12 months is low for a suburb of this profile. The investment case rests almost entirely on capital growth: the 8% price gain over the past year and the suburb's consistent premium positioning relative to state and national medians support a capital-preservation thesis rather than income generation. The 80.9% long-term resident retention rate also limits rental turnover opportunities.

Professional/Tech follows at 15.1% (91 workers) and Education at 13.3% (80), which together reflect the suburb's highly credentialled workforce.

Frequently Asked Questions
Is Netherby a good suburb to live in?
Netherby consistently ranks as one of Adelaide's most affluent suburbs. Household income sits at the 92.7th percentile nationally, the crime rate is low at 20.5 per 1,000 residents, and 80.9% of residents have not moved in five years, indicating high satisfaction. The main constraint is the $2,700,000 median house price, which limits entry to a small buyer pool.
What is the median house price in Netherby?
The median house price in Netherby is $2,700,000 as of 1Q 2026, up 8% from $2,500,000 in 1Q 2025. Weekly rent averages $380 and monthly mortgage repayments run around $2,383, with a mortgage-to-income ratio of 21.7%.
What schools are in Netherby?

Is Netherby safe?
Netherby recorded 31 total offences in the dataset period, giving a crime rate of 20.5 per 1,000 residents. This rate is low compared to broader metropolitan Adelaide averages, consistent with an affluent, low-turnover suburb where 80.9% of residents have lived there for five or more years.
Is Netherby good for property investment?
Capital growth prospects are reasonable: prices rose 8% over the past year from $2,500,000 to $2,700,000. However, weekly rent of $380 against that median implies a gross yield well below 1%, making rental yield poor. Only 16.3% of residents rent, keeping the tenant pool small. Investment suits a capital-growth strategy rather than an income-focused approach.
How is Netherby's population changing?
Netherby's population is 1,510 in a 1.22 km2 footprint. Residential stability is high: 80.9% of residents have not moved in the past five years, against a turnover rate of 19.1%. The median age of 43 is 3 years above the national figure, suggesting gradual aging of the resident base over time rather than significant new household formation.
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.
