public trace
Monthly CPI is the fastest official Australian inflation read and directly informs cash-rate, real-income, and indexation forecasts. This target resolves on 2026-06-24 under a first-print rule, with an expected ~3 weeks lag. The same series can also spawn next release, +3 months, RBA reaction questions.
April CPI cooled from March but remained well above the RBA target band, with housing and transport still elevated. The agent expects a small further easing in May while keeping upside risk from fuel and administered-price categories.

public trace
The resolver is the ABS Consumer Price Index, Australia first release for May 2026, using the All groups CPI annual movement in original terms. The old Monthly CPI Indicator ceased after September 2025, and the complete Monthly CPI is now the headline monthly CPI publication.
Base-rate/reference-class anchor: recent monthly complete-CPI annual readings sit mostly from 3.4% to 4.6%, while the May 2025 base month was unusually soft at -0.5% month over month. Replacing that base with even a modest positive May 2026 month tends to lift the annual rate from April's 4.2%.
Approximate annual-rate bridge: Apr 2026 over Apr 2025 is 1.042. If May 2026 monthly CPI rises about 0.2% and May 2025 was -0.5%, then May annual CPI is 1.042 * 1.002 / 0.995 - 1 = 0.0494, or 4.9% after one-decimal rounding. An 80% interval allowing roughly -0.5% to +0.8% May monthly outcomes maps to about 4.2% to 5.6%.
Counter-consideration: April already showed a fuel-driven pullback from March and seasonally adjusted all-groups CPI fell 0.1%, so a weak May fuel or travel print could keep the annual rate nearer the low 4s despite the favorable base effect.

public trace
The control run persists April all-groups CPI and gives the noisy monthly indicator a wide symmetric interval.

public trace
The pack run gives more weight to housing, transport, and administered-price components, but keeps a broad interval for monthly-indicator volatility.
