Abstract

Extract:

You hear your parents talk about it almost daily. It is always the same. Have you seen the price of petrol? Perhaps there is also a little reminiscence in the question ... petrol never used to be so expensive, why is it so expensive now? I don’t have all of the answers to that question, but I am able to shed some light on why petrol is hovering at around $1.30 per litre in Australia.
