But the current fiscal settings are not the primary cause of the uptick in inflation.
They are, at best, a contributor in some areas of the economy. For example, infrastructure spending during COVID caused prices to rise in construction, more generally.
Other things being equal, cutting government spending, while leaving taxes unchanged, could in theory help reduce inflation. It is incumbent on those arguing for this to specify precisely what they would cut.
To make a difference to inflation, cuts would need to be large, targeting areas where spending is growing the fastest, such as health, the National Disability Insurance Scheme, defence and natural disasters.
Trimming at the margins - for example, cutting public service budgets - would not help much. In any case, the federal government has reportedly already asked public service department heads to suggest where 5% could be cut.
