We just spent some time up at Inskip Point overlooking over Fraser Island.
It is byo everything and you have to put up with drop toilets lol and no showers.
Water available at Rainbow Beach and its free.
It’s $6.15 a day per person. http://www.nprsr.qld.gov.au/experiences/camping/camping_fees.html
There is 5 camping grounds to choose from so room to move some need 4wd access, so be careful where you drive.
Pet friendly, but beware of snakes and pick up your mess bins provided near all exits. Some toilets look like they have been refurbished. Generators allowed just a 9 pm curfew preferred.
