Hi Jon,
SAKSA website has a reasonable description of kiting locations in and around Adelaide.
For some of them you do not need a permit eg. "Chicken Shop" is another popular one and not too bad for beginners. Here is a link:

As to your question re Largs Bay permit you may need to contact Port Adelaide Enfield Council as they are the ones that hand out the fines, I'm not sure what the answer is.
