Petrol prices fall despite refinery fire, but treasurer warns Australians could face economic pain

Petrol prices have continued to fall despite yesterday's fire at a Geelong oil refinery, but Australians could still face "severe" economic consequences, the treasurer warns.

There were concerns fuel supply could have been gutted by the fire at the Viva Energy oil refinery, but the average price for petrol is actually expected to drop below $2/litre across the country over the weekend as global prices fall.

Visiting the stricken plant today, Prime Minister Anthony Albanese said the impact to fuel production at the refinery had been limited.

Queensland Premier David Crisafulli called on the government to open a third oil refinery in Gladstone.

Federal Opposition Leader Angus Taylor agreed, saying Australia needed to get its hands dirty and produce more oil.

"We've got to get more oil out of the ground," he said.

"We've got to drill, drill, drill."
