There is some relief for motorists after at least three oil companies dropped the price of petrol and diesel.
Shell and Gull are now selling 91 octane at $2.15 per litre and diesel at $1.88.
Caltex and Shell say their new prices represent a four cents a litre cut across all fuels.
It follows the biggest two-day reduction in the cost of crude oil since January last year.
Crude oil closed in New York more than $US10 lower than two days ago.
Analysts say the latest fall was triggered by an American Government report showing inventories of crude oil rose by three-million barrels last week.
Light sweet crude closed in New York at just over $US134 a barrel.
