Brisbane households spend more of their wages on road transport than any other capital city, a new report shows.
The Australian Automobile Association'sMarch quarter Transport Affordability Index found the average cost of transport as a percentage of income was 16.3 per cent.
This puts the Queensland capital ahead of Sydney and Melbourne, on 15.2 per cent each.
But Sydney still takes the honours on actual dollar amounts, with households spending an average $429 a week on transport, ahead of Melbourne on $381 and Brisbane on $376.
Nationally, the average Australian capital city household spent $17,912 a year on transport costs, up from $306 from the previous quarter.
"The increase in costs over the quarter reinforces that transport is a significant and unavoidable cost to households," AAA chief executive Michael Bradley said in the report.
The index takes into account the cost of public transport and owning a car, including loan repayments registration, licensing, insurance, servicing and fuel prices.
And Brisbane hip pockets will take another hit in the new financial year when tolls, apart from the Airport Link, in Brisbane will rise.
"This is devastating news for motorists who are already struggling with the high costs of living," RACQ spokesman Paul Turner said on Monday.
Mr Turner said the state government should commit to freezing registration prices for three years.
