The average West Australian household will be slugged an extra $438.40 for utilities and other fees under the 2017/18 state budget.
The fixed charge for electricity supply will rise 10.9 per cent, or $169, while water and sewerage will go up six per cent, or $96.90.
Standard public transport users will fork out an additional $80.60 while students will pay an extra $52 and there will be a five per cent reduction in the discount offered to SmartRider fares.
Increases to motor vehicle fees include 2.8 per cent for injury insurance, 1.7 per cent for licence fees and 5.7 per cent for a vehicle licence charge.
The emergency services levy will increase by an average of 3.35 per cent.
There will be no changes to stamp duty.
Treasurer Ben Wyatt also announced the 25 per cent rebates for seniors card holders on water service charges, local government rates and underground electricity connection charge would each be capped at $100 per household, saving an estimated $84 million over the forward estimates.
Commonwealth concession card holders will still have access to a 50 per cent capped rebate, including $600 for water service charges and $750 for local government rates.
Other changes to concessions include the energy assistance payment increasing to $300 and the Hardship Utility Grant Scheme going up to $20 million in 2017/18.
Overall, the increases will mean a 7.7 per cent rise in annual costs for the average household, but Mr Wyatt said it could not be avoided given the state's dire finances Labor inherited.
"We have had to make tough decisions to help get the budget under control and unfortunately the burden of those decisions need to be shared across the community."
State debt is projected to exceed $42 billion by 2020, with a net operating deficit of about $3 billion forecast this financial year.
Changes to household fees, charges and concessions are expected to reduce the state's net debt by about $238 million over the forward estimates and will begin on July 1.
The government has also announced an increase in fees at ports used by the biggest companies to generate about $95 million in revenue over the next four financial years, but the discount for junior miners using the Utah Point facility will continue.
Opposition Leader Mike Nahan said the government had committed a breach of trust with their mini budget, describing it as a "massive broken promise".
He said self-funded retirees without a Commonwealth concession card and small households would be hit especially hard.
"They're looking at the West Australian public and saying 'you're a bunch of mugs, we can hit you with heavy electricity and water rates now, we can rip out the assistance we give to you and you will forget about it in four years.' Well don't forget," he said.
WA Council of Social Service chief Louise Giolitto said budget repair should not come at the expense of the most vulnerable, adding there should be compensation for those who could least afford the hikes.
