To get ground leases from the various authorities who exercise the rental of crown land pretty well all marina operators have to accept that live aboards will not be allowed. Fortunately most of them appear to ignore the requirement. Sort of like the prostitution thing, it's illegal an a number of states but tolerated as long as everyone behaves.
They do have move on laws which apply south of Gladsrone (I think) but I've never heard of anyone actually being moved on.
Overall it's been pretty quiet on the regulation front in Queensland
for a few years now.
