The latest inflation rate also included the full unwinding of the federal government’s free child care package implemented in the June quarter 2020.
HSBC chief economist Paul Bloxham said stripping out the impact of fuel and child care would have left annual inflation running at 1.9 per cent, and below the inflation target.
