Parents are paying more for child care than most other household goods or services.
In every capital city, the cost of child care is rising much faster than the consumer price index, Australian Bureau of Statistics figures show.
While the CPI rose 1.3 per cent in the year to March, it leapt by 8.5 per cent in the child care sector.
Child care costs grew the most in Melbourne, at 10 per cent, outstripping costs in Sydney, at 8.6 per cent.
Labor used the figures to call on the government to focus on affordability in its forthcoming child care package.
