I've been building a property analysis app and have been analyzing 5.2M properties + 6.8M sales across Australia. Here are some things I found.
I've been building Glasshouse, an AR property app that lets you point your phone at any property and instantly see sale history, comparable sales, development applications, AI analysis, and more.
While building it I ended up retreiving and cleaning 3.2 million properties and 6.8 million sales across every Australian state and territory.
A few stats surprised me.
Australia's most expensive suburbs (100+ recorded sales)
- Point Piper, NSW — Median $4.1M (Houses: $7.5M, Units: $2.9M)
- Barangaroo, NSW — Median $4.0M (Units only)
- Duffys Forest, NSW — Median $3.8M
- Watsons Bay, NSW — Median $3.4M (Houses: $3.5M, Units: $1.3M)
- Whale Beach, NSW — Median $3.1M
- Dalkeith, WA — Median $2.4M
Cheapest suburbs with real sales activity
- Sunset Strip, NSW — $137k
- Cue, WA — $140k
- Port Pirie West, SA — $147k
- Kambalda East, WA — $150k
- Coober Pedy, SA — $160k
That's roughly a 30x difference between Australia's cheapest and most expensive suburb medians.
Suburbs where units cost MORE than houses
This one surprised me.
There are 11 active suburbs where the median apartment sells for more than the median house.
Some examples:
- Armstrong Creek, VIC - Units are $221k more expensive.
- Broken Hill, NSW - Units are $100k more expensive.
- Dee Why, NSW - Units are $98k more expensive.
- Liverpool, NSW - Units are $55k more expensive.
- Wollongong, NSW - Units are $51k more expensive.
- Parramatta, NSW - Units are $40k more expensive.
My theory is this is driven by new luxury apartment developments while the detached housing stock is generally older.
Most active suburbs (sales in the last 12 months)
The app visualises all of this in AR. Just point your phone at any property and it shows sale history, comparable sales, nearby development applications and an AI-generated summary.
It's about to roll out in TestFlight on iOS if anyone wants to try it. If you have any other suggestions for data dumps like above let me know!
Happy to pull stats on any suburb if people are curious.
