If your father was born in Australia to an Australian he is not British and so you cannot inherent his citizenship so your daughter cannot inherit it. Sorry.

This is not how it works. It's how German citizenship (sort of) works, for example, but not British. In your initial summary, the great grandfather is British and the grandfather is British (provided the great grandfather and great grandmother were married at the time of his birth). Nobody else is British. British citizenship is inheritable overseas only in the first generation. All subsequent generations are ineligible and have to immigrate like anyone else.
