Analysts had thought there was some chance the RBA might even pause its tightening campaign, but the sheer pace of inflation put paid to that.
Price rises were broad-based with a closely watched measure of core inflation, the trimmed mean, rising 1.7% in the December quarter.
Costs pressures were also building in the service sector which recorded its largest annual rise since 2008, driven by holiday travel, meals out and takeaway food.
"Strong demand, particularly over the Christmas holiday period, contributed to price rises for domestic holiday travel and international air fares," said Michelle Marquardt, ABS head of prices statistics.
With inflation pressures broadening yet further, markets moved to price in the risk of at least two more rate hikes from the RBA with swaps implying a peak above 3.60%.
