The average price to fill up at the bowser has risen to a near one-year high, as stronger economic conditions push up the demand for oil.
Data from Commsec and the Institute of Petroleum shows the average price of petrol is 152 cents a litre, its highest level since April last year.
The petrol price is up 13 cents since the beginning of the year, which is the strongest rise in four years.
Commsec spokesman Savanth Sebastian says the price increase is being driven by global demand.
"We have seen petrol prices actually surging in the last few weeks," he said.
"Really the drivers behind it is that the global economy is healing, we are seeing investors believing that there is going to be more demand for oil and as a result oil prices have rallied quite sharply.
"You look at the increases and it's been really quite dramatic for motorists." Mr Sebastian says Australia's petrol price has ties to the Singapore unleaded price.
"That's actually holding around the highest level in about 10 months and the rally into the Singapore unleaded price has been quite dramatic in the last two months," he said.
"Those price gains effectively have to filter through to domestic prices." Mr Sebastian says the higher petrol price is not just hurting motorists.
"Even if you don't drive a car you will feel the pain through higher delivery costs, higher transport fares, increases in prices of goods and fruits and vegetables and the like," he said.
"The impact across the economy can be quite dramatic, so that's something that we certainly have to watch over the next couple of weeks."
