Monthly CPI vs citation-grade quarterly YoY
Three stable IDs for three different jobs. Pick the series that matches the question, then carry the citation fields into your app.
Which ID to call
AU.CPI.MONTHLY
Monthly CPI Indicator (ABS 6484.0). Faster release-morning read. Useful for dashboards and agents that need a newer print than the quarterly cycle. Not a substitute for citation-grade quarterly headline CPI.
Series: /series/AU.CPI.MONTHLY/
AU.CPI.YOY
Headline quarterly CPI year-on-year (ABS 6401.0). Prefer this when you need a citable quarterly inflation figure for reports, footnotes, or product copy.
Series: /series/AU.CPI.YOY/
AU.CPI.TRIMMED
Trimmed mean CPI, annual (ABS 6401.0). The RBA-preferred underlying gauge.
Pairs with AU.CASHRATE when you care about policy stance rather
than headline alone.
Series: /series/AU.CPI.TRIMMED/
