Does Price Buy Safety? What Sydney's Suburb Crime Data Actually Shows

Everyone assumes the answer is yes. Pay more, get safer. But when you run the numbers across 277 NSW suburbs, the picture is more complicated than that.

The headline finding

We ran a Pearson correlation between median house price and residential crime rate for every NSW suburb with a population above 3,000 and at least 5 house sales. The result: a moderate negative correlation of r=-0.37.

That's a real relationship, and it's statistically significant. But here's the number that matters most: price explains only 13.5% of the variation in crime rates between suburbs. The other 86.5% comes down to factors that have nothing to do with what you paid.

Expensive does not mean safe.

How crime rates shift across price bands

The chart above shows average safety scores across price bands. There is a real pattern, but it is not linear, and it plateaus in a way that should give buyers pause.

The sharpest safety improvement happens when you cross the $1 million mark. Suburbs under $500K average a residential crime rate of around 2,384 per 100,000 residents. Cross into the $500K-$1M band and that drops to 1,525. Cross $1M and it falls again to 1,034.

But then something interesting happens. Between the $1.5M-$2M band and the $2M-$3M band, the average crime rate is essentially identical: 761 per 100,000 in both. Paying an extra million dollars over $1.5M buys you no additional safety on average. The premium above that level is buying you the suburb's desirability, its proximity to the harbour, its architecture or its cachet. It is not buying safety.

Crime types that do correlate with price

Not all crime moves the same way with price. Here is what the data shows:

Domestic assault has the strongest link to price (r=-0.48). Wealthier suburbs record substantially less domestic violence than the state average. This makes sociological sense: domestic violence is one of the crimes most strongly linked to socioeconomic stress, financial pressure and housing instability. Reducing those pressures correlates with reducing this crime.

Motor vehicle theft also shows a meaningful negative correlation (r=-0.30). Wealthier suburbs have more off-street parking, garages and home security. That matters.

Break and enter follows at r=-0.27. Richer homes have more to steal but also invest more in security systems, deadbolts and alarm monitoring. The effect partially cancels out.

Crime types that barely move with price

Two categories show surprisingly weak relationships with house price:

Steal from dwelling has the weakest correlation of all (r=-0.12), explaining just 1.4% of variation. Whether someone's home gets burgled while they are away depends much more on the specific street and the suburb's density than on how much the house is worth.

Robbery also shows a weak link (r=-0.14). Robbery is a crime that follows people, not property values. It clusters around entertainment strips, transport hubs and high foot-traffic zones.

The expensive-but-unsafe suburbs

This is where the data gets most interesting.

Several of Sydney's most expensive suburbs have crime rates that would embarrass an outer-ring suburb. Glebe sits at $2.95M median with a residential safety score of just 5 out of 100. Surry Hills is $2.45M with a safety score of 11. Waterloo at $1.55M scores 9.

These are not flukes. They share a common profile: dense inner-city suburbs with proximity to entertainment precincts, high foot traffic day and night, and a transient population mix. The crime rate reflects the environment, not the residents.

Alexandria ($2.43M, safety 32), Parramatta ($1.47M, safety 21) and Merewether ($2.31M, safety 12) follow a similar pattern. You can pay a substantial premium and still end up in a suburb where the crime rate is three to five times the state residential average.

The safe bargains

The other side of the coin: suburbs where you get genuine safety at a price well below what the market suggests.

Bowral in the Southern Highlands scores a safety 100 out of 100 at a median price of $1.39M. Springwood in the Blue Mountains does the same at $1.08M. Bungendore near Canberra: safety 100 at $1.03M. St Helens Park in Campbelltown: safety 100 at $872K.

The pattern in the safe bargains is consistent: lower-density suburbs, strong community fabric, limited entertainment precincts, predominantly owner-occupier housing. The suburbs that outperform their price on safety tend to be places where people know their neighbours.

Bangor ($1.73M, safety 100) and South Turramurra ($2.05M, safety 100) are hidden gems in the Sydney basin itself: suburb-priced fairly for their location but well below their crime-adjusted value compared to less safe alternatives at similar prices.

What this means for suburb research

Price is a reasonable first filter for safety, but it is a blunt one. The data shows that:

• The relationship between price and safety is real but moderate.
• The biggest safety improvement comes in the $500K to $1.5M range. Above $1.5M, you are paying for other things.
• Inner-city density is a confounding factor. Expensive suburbs near entertainment precincts often have higher crime than outer suburbs at a third of the price.
• Domestic assault is more strongly correlated with price than break and enter. That matters if family safety is the priority.
• Plenty of suburbs at $800K-$1.1M have safety scores of 90-100. The premium for safety is not as large as buyers typically assume.

Suburb research should treat price as one input alongside safety, transport, schools and liveability rather than a proxy for all of them combined.

Methodology

Property data: NSW Valuer General sales data processed via the Domain API (quarterly). Crime data: BOCSAR (Bureau of Crime Statistics and Research) annual suburb-level data. Population: ABS 2021 Census. Residential crime rate is a weighted composite of break and enter, steal from dwelling, motor vehicle theft, domestic assault and robbery -- the five crime categories most relevant to everyday residential life.

Analysis covers 277 NSW suburbs with population above 3,000 and at least 5 house sales recorded. Suburbs flagged as commercial or tourist hubs were excluded from the safety score chart. Full methodology and data sources.
