South East Queensland Walks and Camping

Hi All,
I am looking to get into multiple-day walks with a group of people and just had a few questions:
- Does anyone here use a hammock for these types of walks? And are you allowed to use the trees surrounding the campground for the hammock? Ever had any hammock related problems? I was thinking of a Hennessy variant.
- I have heard a few people mention bush camping, which I assume was not using the designated walkers camp areas and just going slightly off track to make camp. I presume this is illegal? Does anyone have experience doing this?
- I have looked at the designated 'great walks', are there others that are also good?
Thanks for the advice.
