Western Australia's government is set to keep household fees below inflation while slugging cashed-up miners with higher port charges.
The average household will pay an extra $99 next financial year.
Premier Mark McGowan says keeping fees and charges below the projected inflation rate of 1.75 per cent will put a $377 million dent in the budget.
The Labor government is currently forecast to deliver a $3.1 billion surplus but that figure is likely to be considerably higher by the time the budget is delivered in September given the recent surge in the iron ore price.
The steelmaking commodity surpassed $US200 a tonne earlier this month, although it has dipped over the past fortnight.
