How do you get from Australia to England by boat?

Australians going to England by ship boarding at Sydney or Melbourne travelled along the south coast to Fremantle, then went:

(1) northwest across the Indian ocean, through the Red Sea, Suez Canal and Mediterranean, with stops at Colombo, Bombay, Aden, Port Said and Gibralter; or

(2) around the Cape of Good Hope and up the west coast of Africa, with stops at Durban and Cape Town.
