Australians are spending record amounts on transport costs with motorists paying $70 more per week at the bowser at the end of 2021 than they were a year earlier.
The figures from the latest Australian Automobile Association transport affordability index show motorists were spending $380.10 per week in the last quarter of 2021, compared to $309.92 at the end of 2020.

But it was Hobart and Launceston residents who spent the largest share of household incomes, out of the metropolitan and regional centres.
Hobart residents are spending 18.2 per cent of household income on fuel, nearly three points higher than the national average, despite paying the lowest amount per week at $363.77.

The index follows warnings from the NRMA that the Russian invasion of Ukraine saw a "significant spike" in fuel costs overnight on Friday.
"Unfortunately as feared and predicted, the events of the last 24 hours have led to a sudden increase overnight of world oil prices," the NRMA's Peter Khoury said on Friday.
NSW Premier Dominic Perrottet also warned on Friday the invasion would see people paying more at the bowser.
The federal government has ruled out making changes to the fuel excise, allowing for cheaper fuel, saying any small decrease of a few cents per litre would be swallowed by the rapid fluctuations in petrol prices.
