Oceania (Australia, New Zealand & the South Pacific) - Fraser Island - 4x4 Rental - Help

I pan to visit Fraser Island for some days and want rent a 4x4 in order to be able to drive in the Island. I want to pick up the car already in BNE and return it there too.

I'm facing quite difficulties to get a car company offering cars that are allowed to go to Fraser Island.

Anyone knows any car company that allows it? If so may you please post?
Thank you and regards,

I think you will find that there are none in Brisbane. You are better off making your own way to Hervey Bay and hiring from one of the specialist 4x4 operators there.

There's heaps of them, but here are some examples:
