Rental vehicles need to be returned clean with empty waste/grey water tanks and a full tank of fuel unless pre-arranged. Where a vehicle is returned without a full tank and no pre-arrangement in place you will be charged an administration fee for refueling and high per litre rate (up to $4 per litre) or as is the case with brands owned by the THL group including Maui, Maui Elite, Britz and Mighty, the cost of their express package (circa $300) will be applied. Some providers also require cooking Gas cylinders to be refilled. Your Campervan rental provider will advise you of the drop off details when you collect your vehicle.
