yeah the main beach at hawkesnest is known to shark researchers as a congregation hot spot for white sharks. Not a great place to body drag.
some other beginner freindly spots are
tuggerah lake- the enterance
wallis lake forster
park beach coffs harbour
shearwater gold coast
wellington point brisbane
caloundra river mouth
maroochydoor river mouth
noosa river mouth
plus there are probably many more I don't know about. Obviously these locations appropriateness are subject to certain wind/tide conditions so check the state associations websites and ask locals for advice.
That sounds like a wicked trip have fun, I'm jealous
