I just did the Melb to Brisbane run, did anout 1,600km used average 8.6l/100km. Generally sticking to speed limits, plus the odd shoot to 160km/h to get around those pesky road trains. Filled up in Cranbourne, next fill was West Wyalong (spelling?). Stopped over night at Coonabarabran, 1,000km day is easy in this car (I was by myself), I probably could have done the whole trip in one go I reckon. Only saw 1 roo the whole trip, although I had to brake hard once to avoid an emu that stepped out infornt of me!
