Petrol pricing is a sensitive issue in Australia - witness former PM John Howard's political angst following complaints when petrol hit AU$1/litre. He was at further pains to make the same point the current Labor government does - international petrol prices are beyond its control. The policy has been that Australian prices are tied to the Singapore price of TAPIS crude.
Australia's petrol taxes, and pump prices, are by no means the highest, or lowest, in the world.
In February 2008, the average price across Europe was AU$2.04/litre; NZ was AU$2.28; and Britain AU$2.25/litre. The Australian weighted average was $1.44. In the USA it was about AU$0.85-0.90 (Compiled from information gathered from: RBA; AARoadwatch, Ireland; Australian Institute of Petroleum; Backpack New Zealand. Image from www.coolmob.org)
Petrol is reasonably inelastic - when the price jumps quickly, as it has, people react strongly, but in the longer term will try to reduce consumption either by changing their travel habits an/or by buying more economical vehicles. Many metropolitan and regional areas also suffer from poor public transport planning by our politicians.
Nevertheless in a world where global warming is an issue we cannot ignore, a petrol price that encourages less use is a good thing, despite the pain in the wallet. People need to adjust their expectations of cheap petrol all the time - it is just not going to happen. Politicians should look for other ways to help people, including 5, 10, and 15-20 year plans to help public transport recover from their ravages of the last 15-20 years. The trouble is, that would require them to have some vision beyond the next press conference or election.
