Pretty nice trip. The ferry transfer is okay and leaves exactly on time. The tour with the bus guide is only about 1–1.5 hours, then you have your own time after. You can swim at the beach, so better bring extra clothes. Just be mindful of the time so you don’t get left by the ferry. There are also stores around where you can buy food. The carrot cake is the best! also, please do not touch or feed the quokkas!
