Yep as the others have said you have to check out the east coast no matter what.
Frecient is great also fortisque and maria island isn't too shabby
As Benno said Bay of Fires is awesome, there are a few spots to tuck in and have a look at St Helens.
Honestly you could spend months down here camping, seeing the sites and doing a few trecks and all while driving some of the best twisties
