Its 763km's to Shepparton from the centre of Adelaide!
You would top up on fuel twice I reckon as we did as you need your breaks
You would go Bordertown, Horsham, Bendigo and then to Shepparton
My R32 GTR was excellent on fuel and I got around about 600km to a full tank
But I didnt let it go under 1/4 and needed to stop for breaks to stretch the legs and grab food and drinks
I hope some of you come to DECA, I went down as a spectator as didnt know what to expect in May, but this one in August I am entering
It's a great, fun weekend away and isnt that expensive its about $100 a night for the cabin's but you can split it with people as sleeps 6. We ended up paying $70 for two night each
DECA to enter is $75 but you do need your L2S Cams licence to compete which cost $85 and last's you a whole year
This is DECA:
