Perth petrol prices have climbed to a two-month high, leaving motorists facing some of the most expensive fuel in the nation.

And the pain at the bowser could get worse, with signs oil companies have yet to pass on recent rises in global oil prices.

Australian Institute of Petroleum figures show the average price of unleaded petrol across Perth increased 4.7� to 122.2� a litre over the past week.

It was the highest weekly price for unleaded in the city since the last week of last year.

Motorists in other parts of the country are not feeling so much hip-pocket pain. Prices in Sydney (117.3� a litre) and Melbourne (117.4�) actually fell last week.

Apart from Darwin and Hobart, motorists in Perth are paying the most for unleaded fuel.

CommSec equities economist Savanth Sebastian said yesterday the fall in oil prices had delivered about a $53 monthly windfall to the average household. But rising prices over the past fortnight had grabbed back $13 a month.

Since bottoming at $US52.20 a barrel early last month, the Singapore gasoline price has lifted to $US73.30 a barrel.
