My son and I will be visiting Phillip Island in early June. We have a motel reserved in Melbourne for three nights, so we wanted to spend one day on Phillip Island. We will already have a rental car as we will be driving from Sydney. Is it hard to get to Phillip Island and once we get there is it plenty of parking at the different locations such as The Nobbies, Penguin Parade, and Koala Conservation, or would we be better using some sort of public transportation. Thanks for you help!
