FAQ
Common questions
Where does the data come from?
Victorian data is sourced from the DFFH (Department of Families, Fairness and Housing) Moving Annual Rents by Suburb report, published quarterly under Creative Commons Attribution 4.0.
How current is the data?
We update quarterly. The current dataset covers through September 2025. New data is published by state governments within 2 months of each quarter end.
Which states are covered?
Victoria is currently live with 146 suburb groups and data back to 2000. Additional states are being added progressively — check the /v1/rental endpoint for current coverage.
Can I filter by postcode?
Yes. Use GET /v1/rental/postcode/{postcode} to get all suburbs that map to a given postcode, including their rental history.
What property types are available?
Data is broken down by flat/unit (1, 2, 3 bedrooms) and house (2, 3, 4 bedrooms), plus an 'all properties' aggregate for each suburb.
Is this the same API key as the other Aristocles APIs?
Yes. One key covers all endpoints — rental, PBS, subscriptions, and trade pricing — with the same rate limits and billing.
