For a few minutes I thought about posting a really bad report to keep people away from this fantastic place.
We camped at Easter 2013 for 7 days.
Dilli is the most southern camping area on Fraser Island. We have been to Fraser Island a few times however this is the first time we towed a rather heavy camper trailer.
We picked Dilli to reduce the travel time with the camper which was just as well as the beaches were washed out and we would have needed to use the headland bypass tracks if we had camped further north.
The campgrounds are well maintained, grassed and some are even powered (for light loads as the camp runs on generator)
The amenities are clean and well maintained, one block is very new, however don't expect hot showers, the solar just does not cope. Just suck it up and make it quick, your camping!
We have young kids so the fully dingo fenced site is greatb and peace of mind for safety. We saw dingos most afternoons on the other side of the fence.
Make sure you take firewood as fires are allowed in Dilli, only 1 of 2 places where fires are allowed on Fraser Island.
Dilli is simple and minimalist, there is no laundry but if you need to wash there is a laundromat at Eurong.
Dilli does not seem to be popular with backpackers and as such is very quiet at night.
The caretaker is passionate and determined to provide a great experience, his many years of efforts in what is a very challenging and remote location is a credit to him.
