Mate Woody Head is great.
There is some great rock pools in front of the camp ground you can snorkel in. There is nice big and little beaches up to the mouth of the Clarence. Iliuka is 10mins away and if that's too small you can drive or catch the ferry to Yamba.
You can fish the Clarence and its many tributaries, the little cove next to the camp ground is pretty safe if the wind is from the south. If you have a 4X4 you drive up the beach to Black Rock where there is a small little land locked creek.
If you drive to Yamba you can head a few k's further south and get to Angourie.......plenty to see and do I want to come to.
