Australia has something like the 2nd or 3rd cheapest fuel in the world when compared in relation to the value of the dollar and average weekly earnings, with other countries.
How would you like to live in the UK and pay more in POUNDS STERLING for a litre of fuel than we pay here in dollars?
(p.s- as a side note: at current prices, it's costing around 16c/Kilometre to drive the work car around the Sydney metro area. but that's with a fair bit of A/C usage)
