Blakeley turns the Expedition north to Illbilla, while rearranging the loading on the truck they discover that the wrong engine oil has been packed at Alice Springs. Potential disaster, bet the Captain had nothing to do with this and why is Lasseter always fiddling around with the stores.

Clever Taylor makes some adjustments to the engine to use less oil, Blakeley collects seeds while Taylor toils. The Expedition would go nowhere without the young Englishman and he's turning into a fair sort of an Aussie Bushman too. The journey north while extremely hot is trouble free.

Johns has never had it so good, a holiday in Central Australia, while Coote has one in Adelaide, Hall leaves for Melbourne, another plane another job.
