We booked this trip some time ago and we're not disappointed. It's amazing that the whales journey so close to the land up and down Humpback Highway. There was a lot of activity once we were out at sea and some of the whales came very close to the boat. They also gave a great show, breaching, head lunging and tale slapping.
It was very calm and I'm not sure we really needed the sick sickness tablets - they actually made us feel quite dizzy and sleepy once back on land.
