Do you need to cross the island to drive to Phillip Island (Penguin Island) and Mornington Peninsula from Melbourne ?

"Okay, I should ask. Some are not allowed to cross the island."
Philip Island doesn't count, and Mornington is not even a peninsula, as it is connected to the mainland...
Yes, you need to apply for inter-island travel with the car rental company. The specific regulations of each car rental company may vary, but most of them have inter-island options that include Phillip Island.
I'm not sure about Phillip Island, but there's another one.
