It couldn't be more pleasant to take a boat around the island on a group day tour! The blue sky and blue sea, and you can see wombats.
The local one-day tour only has English. We are the only foreigners. The others are all local Australian aunties and uncles. The sea breeze is still quite cold when the boat starts, but it's worth it for the beautiful scenery.
Some local aunties did a lot of homework and introduced us to the rock types and formation ages along the coast.
