What is a good vacancy rate?

Below 2% is BoomAU's hard suburb-quality filter — it signals tight rental demand. 2–3% is balanced; above 3% means rental supply is outrunning tenant demand and rent growth is unlikely.

What is the vacancy rate?

The vacancy rate is the share of rental properties currently sitting empty in a suburb or postcode. SQM Research publishes it monthly at postcode level for free.

What are vacancy rates in Australia?

Australian suburb vacancy rates typically sit between 0.5% and 5%. Tight markets run below 1%; soft markets exceed 3%. The national rolling average has been near 1–1.5% through 2024–2025.

Where can I find vacancy rates by suburb?

SQM Research publishes free postcode-level vacancy rates back to 2005 at sqmresearch.com.au/property/vacancy-rates. BoomAU uses the same series as a hard filter in its boom-detection formula.

Methodology

Numbers are calculated from BoomAU's htag-suburbs.csv dataset and refreshed every 14 days. See /proof for the full methodology, source feeds, and known limitations.

Vacancy is reported at postcode granularity from the SQM source. Sibling suburbs in the same postcode share a vacancy figure.
