Mordialloc
Semi-detached housing at 45.6% is the largest dwelling type in Mordialloc, exceeding separate houses (39.8%), a housing mix that is rare in Melbourne's bayside suburbs and reflects significant townhouse-era redevelopment. Crime rate of 97.3 per 1,000 residents is notably higher than the Victorian average of around 65, yet SEIFA decile 9 and university attainment 14.5 percentage points above the national rate confirm this is a high-income, educated suburb. House prices reached $1,195,000 median, growing 75.7% from $680,000 since 2013.

At $1,195,000, Mordialloc sits at a moderate premium for bayside Melbourne. The unusual housing mix means 45.6% of stock is semi-detached (townhouses), which typically prices 20-30% below detached houses, providing a more accessible entry than the headline median suggests. Three-bedroom homes (35.5%) and 2-bedroom (31.9%) are most common, reflecting the townhouse density. Mortgage-to-income at 24.6% is manageable on household income in the 76th percentile. Prices are 22.1% below the July-September 2023 peak of $1,535,000, one of the larger corrections in this batch, which may signal a buying window.

For Investors
Renters at 30.2% and $400/week rent face a 7.3% vacancy rate, above the metro norm. The 50 development applications in 12 months include warehouse and industrial-use permits alongside residential, indicating a mixed-use suburb with commercial tenant potential. Population grows at 0.93% per year (+208 people), driven by overseas migration (+343/year) while internal migration is negative (-118/year). Rent grew 33.3% over the decade, ahead of CPI. Long-term capital growth of 4.1% CAGR over 14 years is solid if modest. The 22.1% gap from peak to current price could mean value for patient investors.

Four schools serve the area with strong ICSEA scores: Mordialloc Beach Primary (1095, 249 students), St Brigid's Catholic Primary (1091, 169), Parkdale Secondary College (1067, 1418), and Mordialloc College secondary (1062, 1218). All exceed the national benchmark by 62+ points. Public transport at 5.1% and walking/cycling at 4.2% give 9.3% non-car commuting. Crime rate of 97.3 per 1,000 is notably elevated for a SEIFA decile 9 suburb; property offences (477 of 865 total) drive this figure, possibly inflated by commercial-zone activity. IRSAD decile 9 confirms upper-tier advantage.

Real income grew 17.3%, and affordability improved from 44.3% to 40.9% (mortgage-to-median-income) because incomes outpaced prices at the longer timeframe, despite the recent cycle.

Frequently Asked Questions
Is Mordialloc a good suburb to live in?
Mordialloc offers strong schools (all ICSEA 1062+), bayside location, and SEIFA decile 9 advantage. The unusual housing mix (45.6% townhouses, 39.8% houses) provides varied entry points. The main concern is the crime rate of 97.3 per 1,000, higher than the state average of 65, driven primarily by property offences (477 of 865 total) rather than violent crime.
What is the median house price in Mordialloc?
The median house price is $1,195,000 as of April-June 2024. Prices grew 75.7% from $680,000 in 2013 at a compound annual rate of 4.1%. The current median sits 22.1% below the July-September 2023 peak of $1,535,000, the deepest correction in this batch, which could represent value for long-term buyers.
What schools are in Mordialloc?
Four schools serve the suburb: Mordialloc Beach Primary (ICSEA 1095, 249 students), St Brigid's Catholic Primary (1091, 169), Parkdale Secondary College (1067, 1418), and Mordialloc College (1062, 1218). All exceed the national ICSEA benchmark of 1000 by at least 62 points.
Is Mordialloc safe?
The crime rate of 97.3 per 1,000 residents is higher than Victoria's average of approximately 65 per 1,000. Property and deception offences account for 477 of 865 total incidents, while crimes against the person total 143. The elevated rate may partly reflect commercial-zone activity in the mixed-use parts of the suburb rather than purely residential crime.
Is Mordialloc good for property investment?
Long-term CAGR of 4.1% over 14 years is solid, and the 22.1% gap from peak to current price could create a recovery opportunity. Vacancy at 7.3% is above the metro norm, and renters at 30.2% pay $400/week. The 50 DAs in 12 months include both residential and commercial uses. Overseas migration (+343/year) supports demand, but internal migration is negative (-118/year).
How is Mordialloc's population changing?
Population grows at 0.93% per year, adding about 208 people annually, projected to reach 23,713 by 2031. Overseas migration (+343/year) drives growth while internal migration is negative (-118/year). The decade growth of 13.2% is close to Melbourne's average. Real income grew 17.3% and gentrification score of 15 confirms established affluence rather than transitioning demographics.
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.
