Cockburn property market
Cockburn is one of the 453 council areas we track on the Momentum Dial, our property clock. This page is the plain-numbers read: where it sits in the cycle, who lives there, what's being built, and the suburbs inside it.
Cockburn is home to 139,499 people. On the Buyers First Momentum Dial its house market currently reads Slowing, and units read the same. The number that matters most here: population is compounding at +3.2% a year. People arriving is the rawest form of housing demand. Here's the rest of the picture, in plain numbers.

The numbers, explained
Cockburn in charts.
The typical house in Cockburn went from $500,088 in 2010 to $1,224,742 in August 2026. That is +145% in total, +5.5% a year. It went backwards 5 years in a row at one point. Any market can have a bad year. The ones that stack them are the ones that hurt, and this is the number we weigh most.

What this shows. How much the typical house price in Cockburn went up or down each year. Teal bars are up years, red bars are down years, and the faded bar is this year so far.
Why it matters. The size of a good year matters less than how many bad years there were and whether they came in a row. Boring? Absolutely. But the length of the down stretch is what decides whether you get out the other side. Typical price at December each year, data from HtAG Analytics.
You don't need to know property to read this. Every chart below opens with the point in one line, then says what it shows and why we care. Teal is a good sign, amber is okay, red means watch it.
The scorecard · 7 things we check
Cockburn scores 22 out of 35. Mixed.
prices are still rising but more slowly
6 of 15 years
2.6 new homes approved per 100 that exist
population growing 3.2% a year
3.6% unemployed, Australia 4.2%
a house costs 9.9 years of a local household's income
1.0% of rentals are empty, so about 1 in every 100
What this shows. Seven quick checks on Cockburn, each scored out of five. Five is the reading we most want to see.
Why it matters. No single number tells you whether an area is a good buy. Together they show whether the pieces line up. These are bands, not rules: a council outside a band can still be the right buy for the right person, and one inside every band can still be wrong for you.
House prices since 2010 · Cockburn vs the 5 most similar councils in WA
Cockburn has outgrown similar councils over ten years
+15.4% vs +16.0%
A year, last 5 years
+8.5% vs +7.1%
A year, last 10 years
+6.1% vs +5.0%
A year, last 15 years
What this shows. The typical house price in Cockburn every year, in teal, next to the middle of the five councils in WA closest to it in size and starting price: Gosnells, Rockingham, Melville, Armadale, Joondalup. The small "vs" number in each tile is those councils.
Why it matters. Beating its peers over a whole decade is worth more than any single hot year. It usually means something real is pulling people here.

Houses sold, last 12 months vs the 12 before
What this shows. Two versions of the same price. The dotted teal line averages the last three months, so it reacts fast. The grey line averages the last twelve, so it moves slowly. The bars are how many houses sold each month.
Why it matters. The last three months are running ahead of the last twelve. That is what speeding up looks like before it shows in the yearly number.
New homes · approvals as a share of all the homes here
New homes in Cockburn are keeping pace with the people
What this shows. For every 100 homes already in Cockburn, how many new ones the council approved each year. The teal band is the range we call balanced.
Why it matters. New homes are arriving at about the pace the population absorbs them. Balanced. The home count is the population divided by the average household size, so treat the rate as a guide rather than a census.
Affordability · house price in years of local household income
A house in Cockburn costs 9.9 years of a local family's income
What this shows. Take the typical house price and divide it by what a typical household here earns in a year. A bar of 7 means seven years of the whole household's income buys one house.
Why it matters. Expensive for the people who live here. Prices at this level need outside buyers to keep moving, and outside buyers are the first to leave when things wobble. Income is the 2021 Census figure carried forward at 3.5% a year, so it is an estimate, not a measurement.
Rents · typical weekly house rent, last 36 months · and how many rentals sit empty
Rent in Cockburn is $734 a week, up 6.2% in a year

A week, August 2026

Rentals sitting empty (tight)
What this shows. What a typical house in Cockburn rents for each week, month by month. The empty-rentals number is the share of rental homes with nobody in them: under 1.5% is tight, over 3% means tenants have plenty of choice.
Why it matters. Rents rising faster than inflation means more people want to live here than there are homes to rent. That pressure eventually shows up in prices.
Rental yield · a year of rent as a share of the price, Cockburn vs similar councils
Rent covers 3.1% of the price each year in Cockburn
What this shows. Yield is simple: a whole year of rent divided by the house price. A $500,000 house renting for $500 a week earns $26,000 a year, which is a 5.2% yield.
Why it matters. Lower than similar councils, which are around 3.5%. Prices have run ahead of rents, so you are paying more of the loan yourself while you wait for growth. We don't buy on yield alone and we never set a yield cut-off; it is one piece of the picture, next to growth.
The people
Who lives in Cockburn.
The population has grown +3.2% a year over the last five years, which is quick by national standards. Overseas migration is doing the heavy lifting, 6,903 people on net over the last three years. The median age is 37 and the median household brings in $1,995 a week (Census 2021). 73% of households own or are paying off their home. Owner-occupier markets like this tend to hold their nerve through the cycle, because nobody is forced to sell an address they live at.

A year, last 10 years
Why it matters. People arriving is the rawest form of housing demand. Every new household needs somewhere to live before anything else happens.
Where the growth came from · last 3 years
Overseas arrivals are doing the heavy lifting in Cockburn: 6,903 in three years
Net change: +14,198 people over three years.
What this shows. Three ways a place gains or loses people: babies born minus people who died, people who moved here from another part of Australia, and people who arrived from overseas. Bars to the right add people, bars to the left take them away.
Why it matters. Overseas arrivals usually rent first, so this kind of growth shows up in rents before it shows up in prices.
Age and households · Census 2021
Cockburn is younger than the typical WA council: median age 37 vs 42
Cockburn Typical WA council (middle of 103)
Why it matters. A younger area means first-home buyers, growing families and renters. Three-bedroom houses near schools and jobs are the bread and butter.
Income and who owns the homes · Census 2021
Most homes in Cockburn are owner-occupied: 73% own or are paying off, 25% rent
Own or paying off Renting Other
Why it matters. Owner-occupier markets hold their nerve through the cycle, because nobody is forced to sell the address they live at.
New supply
What's being approved to build.
1,379 dwellings were approved in FY26, 871 of them houses. Approvals are clearly trending up, so more supply is coming. Whether that's a problem depends on whether the population keeps outrunning it. On the non-residential side, $444 million of building was approved in FY26, $87 million of it public money. Governments build where they expect people. Within that, $63 million of education and health buildings have been approved across the last three financial years. Schools and hospitals are the most honest signal governments give about where they expect families.

Who employs people here · Census 2021
Health care and social assistance is the biggest employer in Cockburn, 14% of jobs
What this shows. The five industries that employ the most residents, as a share of all jobs. The pill is the ABS advantage score: Cockburn sits in decile 9 of 10 nationally, where 10 is the most advantaged.
Why it matters. A spread of employers means no single closure can empty the town. That is the kind of job base that holds house prices through a downturn.
The outlook
Is Cockburn worth buying into?
Put the drivers together and the case for Cockburn is: a population that keeps growing, net internal migration in its favour, a job base that has expanded. None of this guarantees anything. It tells you where to look harder, which is what a report like this is for.
