One Big Switch helps to make petrol even cheaper

Motorists looking to snare even cheaper petrol prices when filling up are in luck, thanks to people power.

Almost 100,000 Australians have joined the fight to further push down the cost of fuel, which has continued to drop since October after a fall in world oil prices and declining demand.

The Big Cost of Living Switch campaign has succeeded in unlocking another group-discounted fuel offer for motorists starting today.

The deal will provide customers with a 5 per cent discount off BP fuel cards and is valid for 12 months.

One Big Switch campaign director Joel Gibson said while petrol prices varied nationally, it was great for motorists to enjoy lower prices in the past few months.

"It's been so high for so long so people are finally getting some relief," he said.

"But grocery prices have gone up 6.8 per cent in the past year so it's swings and roundabouts. This deal is a good opportunity for people to save 5 per cent on petrol." Customers can purchase the prepaid fuel cards for either $100 or $500 credit and enjoy a 5 per cent discount.

The cards can be used at BP service stations for all fuel and in-store products. Petrol prices in Sydney, Melbourne and Adelaide have continued to fall and remain just above $1 a litre.

But Mr Gibson said in some regional areas of Australia, motorists were still paying around $1.50 a litre.

The Australian Institute of Petroleum found the national average price of petrol fell by 2.3c in the week to January 4 and the national average petrol price is 121.9c a litre.

This is the lowest in more than four years.

Australian Automobile Association's acting chief executive officer James Goodwin said while petrol prices had come down, motorists should look around for the best price. 'Consumers should look around and visit the motoring club website in their state to see where the lowest prices are," he said.
