The big T have launched a guide to petrol prices on their 3 G and Next g
portals. You have to go to the Travel & info link on the bigpond home
page and the application is listed as MyFuel.
It lets you enter a suburb or postcode search and returns you the list
stations and the current price at the pumps for each of them for each
type of fuel.
Looks fairly comprehensive and I was able to buy at $1.11 near where I
work instead of 1.17 close to home.
They are allowing people to access it for free too so the savings are
savings.
My old man drives a Territory, takes 100lt or so to fill it so $6 a
fill savings 3 or 4 times a month is not bad.  
I thought I'd pass it along cause I don't see an ad for it anywhere.
