Australia's privately surveyed monthly inflation gauge comes from the Melbourne Institute of Applied Economic & Social Research at the University of Melbourne:

Headline inflation jumped 1% m/m in December, from 0.3% in November

  • This is the biggest leap higher in 17 months
  • For the y/y, comes in at 5.2% in December, way above the 4.4% recorded in November

Monthly trimmed mean inflation +0.9% in December

  • this equals the highest ever jump m/m for this indicator

For the y/y, +5.2% in December

from 3.8% in November

  • the biggest move higher since May 2023

Prior to the Australian Bureau of Statistics' monthly inflation survey beginning this from the Melbourne Institute was the only guide we had to monthly inflation. It was, and remains, a well-respected survey.

Its completely at odds with the latest from the ABS, although that was for November, not December:

The ABS publish the December month results on January 31, although it's the quarterly data published the same day that the focus will be on:

Australia December Q4 2023 inflation due 2

The RBA is concerned that inflation in Australia is sticky above its 2 - 3% target band. This data would seem to reinforce that concern.
