What the public data says about Coolbinia: who lives here, what the offence rates are, and where the figures sit against the rest of the state.
Suburb summary
Coolbinia is small, tightly held and overwhelmingly owner occupied. Of just 583 dwellings, 82.8% are owner occupied, split almost evenly between homes owned outright at 41.2% and those carrying a mortgage at 41.7%. Separate houses make up 85.6% of the suburb, while only 15.3% of dwellings are rented. This is not a suburb with a deep pool of stock turning over regularly.
The income profile is what really jumps out. Median weekly family income is $4,166 compared with $2,112 for the middle Western Australian suburb, yet full-time employment is only slightly higher at 57.1% against 56.2%. Unemployment is lower at 3.3%. Education tells a similar story, with 46.5% holding a bachelor degree or higher compared with 23.9% across WA. Households average 2.8 people and, combined with the dominance of separate houses, Coolbinia reads very clearly as a family suburb with a lot of established wealth.
Crime is low across every measure shown. Overall crime probability is 2.9 offences per 100 residents against a middle suburb of 7.1, while burglary, property damage and assault all sit below the middle as well. The only thing to keep in mind is the small population. With 1,751 residents, a handful of incidents can move the rate noticeably from one year to the next. A motor vehicle theft rate of 0.00 simply means none were recorded in 2025.
Knome would expect buying here to require patience. There are only 583 dwellings in the entire suburb and most of them are held by owner occupiers, so the available pool is small before you even start applying preferences around street, condition or layout. For an owner occupier, that means being ready when the right property appears. For an investor, the rental market is genuinely thin, so scarcity should not automatically be mistaken for rental depth.

Rated figures show where this suburb sits among Western Australian suburbs. Strong is the better half of the state and the far end is the outermost quarter, so the word means the same on every row. The scale always runs low to high, so green is on the right where more is better and on the left where less is.

Against an address, not a suburb
Four more checks only mean anything against a real address, because the answer changes between two streets and sometimes between two sides of one. They are what the free Red Flag Report runs, on screen, in seconds, without asking for anything.
Whether the property sits in a bushfire prone area on the state's mapping.
Whether the floodplain mapping reaches the block, which the suburb name never tells you.
Distance and exposure to the roads that carry the traffic, street by street.
Where the property sits under the Perth Airport flight paths and noise contours.
