Your Street's Crime Rate Is Not Your Suburb's
In every suburb, crime concentrates on a few streets. The quiet cul-de-sac and the dodgy shops share a postcode. We mapped 368,000 microburbs to show you exactly which is which.

Type "Chatswood crime rate" into Google. You get one number. That number averages together a quiet residential cul-de-sac at 88 per 100,000 and a busy commercial strip at 25,245 per 100,000. These two streets are in the same suburb. Same postcode. Same school catchment.
They are 286 times apart.
Every suburb in Australia has this problem. The "crime rate" you see on any property portal is a suburb average. It tells you almost nothing about the actual street you are buying on.
We modelled crime at the microburb level. A microburb is roughly 20 households. We built a synthetic model using proprietary data and techniques to map crime across 368,255 microburbs nationally. The variation within suburbs dwarfs the variation between them.
The price difference between the safest and riskiest microburb in a typical $600,000 suburb. That is an 8.2% gap. Same suburb name. Same postcode. Different microburb. Different price.
See It For Yourself
Green is safe. Red is high crime. Each coloured shape is one microburb. Hover to see the rate. Notice how crime clusters in specific blocks, not evenly across the suburb.
Chatswood: 286x range. Quietest microburb: 88 per 100k. Busiest: 25,245 per 100k.
Parramatta: 308 microburbs, 6 hotspots. The residential streets are safe. The CBD strip is not. 2% of microburbs hold most of the crime.
This is why suburb averages fail
A buyer searching "Parramatta crime rate" sees one number. That number averages the quiet residential microburbs with the commercial strip near the station. One has a rate of 1,084 per 100k. The other: 68,768 per 100k. They are 63x apart. Same suburb.
Real Suburbs, Real Numbers
The national median across all crime categories is 2,788 per 100,000. Here is what the data looks like in suburbs you know.
Mosman, NSW 2088
Sydney harbour, 25,447x range
24% lower
Median crime 2,127 per 100,000. But the range across 441 microburbs runs from near zero to 25,447. The quiet streets behind Balmoral Beach are a different world from the Spit Road commercial strip.
Cronulla, NSW 2230
Shire beachside, 182x range
57% lower
Median crime 1,205 per 100,000. One of the safest beach suburbs in Sydney. But the mall precinct has a rate of 14,192. Residential streets one block away: 78.
Cottesloe, WA 6011
Perth premium beach, 158x range
102% higher
Median crime 5,635 per 100,000. The high median is driven by the hotel and pub strip near the beach. Residential microburbs further up the hill sit at 496 per 100,000.
South Yarra, VIC 3141
Melbourne Chapel St, 26x range
151% higher
Median crime 6,983 per 100,000. The quiet microburbs near Fawkner Park are 60% below the suburb average. Chapel Street: 3x the average. Same suburb, two different worlds.
Fortitude Valley, QLD 4006
Brisbane nightlife, 61x range
103% higher
Median crime 5,669 per 100,000. The nightlife strip drives it up. The residential microburbs near New Farm sit at 536 per 100,000. Buyers in the quiet pockets get a different suburb.
Noosa Heads, QLD 4567
Noosa holiday market, 35x range
30% lower
Median crime 1,946 per 100,000. Safe overall. But Hastings Street and the commercial precinct push some microburbs to 16,072. The residential streets behind the national park: 462.
Bondi, NSW 2026
Bondi: the exception
11% higher
Median crime 3,084 per 100,000. Only 17x range. High density and tourism push rates up evenly. Unlike most suburbs, there is no dramatic split between quiet and busy microburbs.
Fremantle, WA 6160
Fremantle: genuine outlier
1,538% higher
Median crime 45,663 per 100,000. 52% of microburbs are in the national top 1%. This is not a few hotspots in a safe suburb. The crime is spread throughout. A genuine red flag.
What We Found
Density is the biggest factor. The more tightly packed the buildings, the higher the crime. This holds across every category. Violent crime. Property crime. Drugs. All of them. A crowded block with shops next door has more crime per person than a spread-out residential area.
Near a pub matters more than near a police station. For violent crime, distance to the nearest pub is one of the strongest factors. Every extra kilometre from a pub drops the violent crime rate by about 120 per 100,000 people. Nightlife areas attract crowds. Crowds produce incidents.
Property crime is 53% of all crime. When people worry about "crime rates," they are mostly thinking about break-ins and theft. Violent crime is 17%. Understanding what type of crime is common in your area matters more than a single headline number.
Your surrounding area matters more than your block. A quiet residential street next to a shopping strip has higher crime than the same street surrounded by parks. The area within 2km has a bigger influence than your immediate block.
Safety or Vibrancy? The Real Trade-Off
At first glance, the safer microburbs seem more expensive. An 8.2% premium for the safest over the riskiest in the same suburb. That is $49,000 on a $600,000 property.
But when we controlled for how convenient and lively each microburb is, the picture flipped completely.
The quiet cul-de-sac vs the busy strip
In any suburb, the quietest residential streets have the lowest crime. They also tend to be furthest from the shops, cafes, and train station. The bustling microburbs near the action have more crime. They also cost more.
When we compared microburbs with the same level of convenience and lifestyle character, the higher-crime microburbs sold for more, not less. You pay for vibrancy near the shops. The quiet cul-de-sac is safe but you give up walkability.
Crime marks vibrant places, not dangerous ones. Controlled for convenience, higher-crime microburbs sell for 19.9% more than equally convenient safe ones. The "safety premium" is actually a "distance from the action" discount.
Real Suburb Stories
Mosman, Sydney
One of Australia's wealthiest suburbs. Median house price over $4M. And crime rates that range 25,447x across its 441 microburbs. The quiet streets behind Balmoral Beach have near-zero predicted crime. The Spit Road commercial strip and the Military Road shops push some microburbs above 25,000 per 100,000. Wealth does not equalise crime within a suburb.
South Yarra, Melbourne
A tale of two halves. The quiet microburbs near Fawkner Park have crime rates 60% below the suburb average. The Chapel Street strip has rates 3x the average. Same suburb, very different microburbs. You can buy in the quiet part and walk to the action. That is the trade-off.
Cottesloe, Perth
Perth's premium beach suburb. Median crime rate is 102% above national because the pub and hotel strip near the beach generates high per-capita rates. But the residential streets up the hill sit at 496 per 100,000. A 158x range. The suburb average tells you nothing about the street you are buying on.
Noosa Heads, Sunshine Coast
A holiday and investment hotspot. 30% below the national median overall. But Hastings Street and the commercial precinct push some microburbs to 16,072 per 100,000. The residential streets behind the national park: 462. A 35x range in a suburb most people think of as uniformly safe.
The 20% Hotspot Threshold
Most "high crime" suburbs are not actually dangerous throughout. The crime clusters in specific microburbs, usually near commercial strips, nightlife, and transport hubs. The residential streets one block away can be completely safe.
But there is a tipping point. Suburbs where more than 20% of microburbs are hotspots grew only 38% over 5 years vs 53% for the national average. A few hotspot microburbs in an otherwise safe suburb is normal. A suburb that is mostly hotspots is a genuine red flag.
| Hotspot Concentration | Suburbs | 5-Year House Growth |
|---|---|---|
| No hotspots (0%) | 8,637 | 53.4% |
| A few (1 to 5%) | 447 | 56.8% |
| Moderate (5 to 20%) | 281 | 58.8% |
| Concentrated (20%+) | 78 | 38.1% |
Parramatta: 308 microburbs, only 6 hotspots
Parramatta has a reputation for crime. But only 2% of its microburbs are in the top 1% nationally. The hotspots cluster around the CBD and station. The residential streets to the north and south have crime rates below the Sydney average.
How This Helps You
If you are buying a home: Check the crime profile for the actual streets you are considering. Not the suburb average. The specific microburb. Two streets in the same suburb can have completely different risk profiles. Chatswood at 2,300 per 100,000 sounds moderate. But that number contains microburbs ranging from 88 to 25,245.
If you are investing: A low-crime microburb in a "high-crime suburb" may be undervalued. The suburb label drags the price down. The street-level data tells the real story. Crime rates affect rental demand, insurance costs, and how a property feels to tenants.
If you are comparing suburbs: Instead of looking at one number per suburb, see the full range. A suburb with a high average and a tight range is genuinely high-crime throughout. A suburb with a high average but a wide range likely has safe pockets hidden inside a bad reputation.

This is a Microburbs research project. We built a synthetic model using proprietary data and techniques to map crime at street level across 368,255 microburbs nationally.
The data is not perfect. It uses resident population as a denominator, which inflates rates in commercial areas. And it captures a snapshot in time, not a trend. But the alternative — pretending suburb averages are good enough — is worse.
