Hi @Brenda5, I love kayaking and used to do so in Adelaide and Coffs Harbour but in Darwin it's out of the question due to crocs and box jellyfish so it's been a while. I might look into dragon boating though. Hopefully all those paddles plunging into the water will keep the crocs at bay.
My trick for an energetic AND relaxing kayak adventure around Coffs Harbour was to put the kayak in at the mouth of a creek on high tide and paddle up stream. Without a tide to battle it was an easy and beautiful trip poking around the mangroves. By the time I was sick of it the tide had turned and I could just gently float back to the mouth on the current. I also didn't need to worry about getting pushed out too far to sea or encountering chop. If there are small creeks around Burrum Heads this technique may be a good way to start.
