Insert speculation on petrol price cycle here.

Price seems to swing from around $1.15 to $1.43 in Brisbane for example, tho based on what I've seen it sometimes dips below $1.10.

So if we take off the 10% GST and the petrol excise of $0.396, the companies are actually selling fuel for between $0.65 and $0.90 per litre, which means that often times the petrol companies are raising their prices by 40% overnight!

/engage pitchforks now.

I drive a diesel, so I'm destroying the environment, and luckily for me diesel price seems to sit very steady at around $1.25-$1.30. Might just be that whilst the companies are comfortable screwing over consumers, they know well enough to leave the big fish (trucking/transport companies) alone. Could you imagine if the cost of moving goods around the country fluctuated so wildly on a weekly basis?
