Try this then.... Overseas companies investing in Australia get some sort of rebate from, you guessed it, the Government..... So down the road at Kings Canyon Resort - Shell and an overseas company at the Resort..... Govt rebate applies. 38 km away - Family owned business... aussies through and through ....no rebate... so cost is reflective of what it costs to bring the fuel here (same as Curtain Springs).....not a great profit margin at all actually.
Cheers.
