Australian postcodes, read like a publication
Every suburb in Australia, by the numbers that matter.
One search box for any suburb, postcode, council area or state. Behind each result: 2021 Census demographics, SEIFA advantage, income, rent, schools and more.
Coverage from the Australian postcode dataset (Matthew Proctor), with demographics from the ABS 2021 Census and council areas from the ABS ASGS 2021.
Why this exists
A postcode is just four digits. A suburb is a story about income, housing, age and opportunity.
We join the official open data, the 2021 Census, SEIFA 2021, ACARA schools and ASGS geography, into one honest page per place. No property listings, no scraping, no spin. Just what the records actually say.
