Barely moved: The price of groceries.
Tony Abbott has said it in freezer businesses and dairy plants, window makers and police stations: the carbon tax was a $550-a-year hit on household budgets. But with the tax gone, families are unlikely to feel such a weight has been lifted from their shoulders.
The $550 figure was based on Treasury modelling prepared for the Gillard government when it introduced the carbon price in July 2012. Almost half of this was made up of projected increases in the price of electricity and gas. The rest of the expected impact was made up of small increases in a long list of goods and services such as food and groceries, clothing, pharmaceuticals and transport fares, many of which Treasury tipped to rise by less than 10¢ a week.
Matt Levey, the director of campaigns for consumer advocates Choice, said much of the impact of the carbon tax repeal will be hard to spot.
''It may be that they don't see some prices increase as much as they otherwise might have, but it's not going to be like receiving a $500 payment over 12 months,'' he said.
Mr Levey said the repeal of the tax should wipe about $200 off the average household's annual electricity bill. The Australian Competition and Consumer Commission has been given new powers to ensure power and gas companies pass savings through to consumers. But Mr Levey said consumers shouldn't expect power prices to return to pre-carbon tax levels, because other factors, such as infrastructure spending, have also pushed up prices.
Similarly, while gas prices will be lower than they would be with the carbon tax, changes which will allow eastern Australian gas to be sold on the international market will push up the bills of Australian consumers.
The suppliers of other goods and services such as food, clothing and transport are not legally required to pass on savings resulting from the repeal of the tax, and it's uncertain how the prices of these will change.
For example, Qantas and Virgin have said their fares will not drop and Woolworths says it absorbed the cost of the tax and so won't be dropping prices.
Even if consumers buy their food and groceries from outlets which did increase their prices with the introduction of the tax, Mr Levey said the size of the impact - 10¢ or less a week for many categories of goods - is small compared to the price movements that happen each week with items going on special or seasonal variations.
''Consumers shouldn't be expecting to be able to clearly identify every one of those costs week in and week out because some of them were very small, some of them were clearly never passed on, and in other areas prices have moved on in the meantime.''
