Each would consist of about six people travelling in three Land Rovers, some of the members being from the British Museum (Natural History) and some from Australian museums, assisted by amateurs from both countries, and each would last about six months.

D. Macdonald to visit on the first Expedition as many State Museums as possible to prepare the way for subsequent expeditions. In addition each expedition had to end up and store vehicles and equipment at some place from which it was practicable to start the next expedition six months later.
”The basic plan was as follows:
