We didn't really expect to see anything but lo and behold after only a few minutes we saw 2 whales cruising up the coast, quite close to shore. We were lucky because there was a bloke at the lookout with binoculars and he told us when he could see them, otherwise we might have missed it.
Apparently the whales swim up the coast this time every year looking for warmer waters. These ones were swimming along quite slowly, popping up every now and again to breathe. They had a really cruisy vibe which was relaxing to watch.
Here's a picture of one:
