Well Nils it looks like no-one has answered and while I havent cruised outside of the SEQ area, we find it a constant pain with all the regulations
are not allowed on any National Park islands controlled by either the Queensland
EPA or the Great Barrier Reef marine
Park Authority. Basically that means no islands north (and including) fraser island. As long as your dog can stay on board or you dont mind heading to the mainland to let him off, you should be right. As you mentioned, there are no dog rules in marine
parks which only go to the low tide mark and National land based parks dont start until the high tide mark. Stay between the tides (this doesnt include Great Barrier Reef
Authority Islands north of bundaberg) and you and your dog/s are not breaking the law. You will find lower numbers of rangers on islands other than in Moreton Bay and Fraser Is. but they are there and if you get caught, fines are not unheard of. Usually a warning comes first though. Doesnt it drive you mad that you can FWD on a beach but not have a dog there!!
