You said that it is $1.13 per liter. I am assuming that that is in AUD. $1.13*3.78541 = AUD4.2775*0.7599 = USD3.25. This is much cheaper than what I pay. People think that "petrol" is so cheap in the US. That is only the case if you do not live in California.
This graph shows that Australians spend less money on "petrol" as a percentage of their annual income than Americans. Even though, it says that the average price per gallon is $2.74, I pay about $4.30 per gallon. That is USD1.13 per liter. I had heard that the price per liter was more on par with the UK than with us. You are lucky. It is cheaper than mine.
In fact, Norway pays even less. Even though "petrol" prices are absurdly high there, they have an extremely purchasing power parity to balance it. They spend 0.68% of their annual income on "petrol". That is a third of the amount we spend here.
