He arrived there safely, after having had two more skirmishes with the blacks on the way.

He reported the finding of the camel tracks, and having come to the conclusion that Burke and Wills had probably made for the Queensland settlements, he decided to follow them thither.

He traced out a tributary of the Flinders, the Saxby, on his homeward route, but saw no more of the camel tracks, and finally crossed the water-shed on to the rough basaltic country at the head of the Burdekin.

Here his horses suffered so severely from the rugged nature of the country, that by the time they reached Strathalbyn, a station on the lower Burdekin, the whole of the party were well-nigh horseless, as well as almost out of provisions.
Walker was afterwards engaged by the Queensland Government to mark out a course for a telegraph line between Rockingham Bay and the mouth of the Norman River in Carpentaria.

This work he carried out successfully; but when at the Gulf, he was attacked by the prevalent malarial fever, and died there.
10.2.BURDEKIN AND CAPE YORK EXPEDITIONS.
The main portion of eastern Australia was now fairly well known; it had been crossed from south to north, and from east to west, and it was only the elongated spur of the Cape York peninsula that stood in urgent need of detailed exploration.
Amongst what may be called the minor pastoral expeditions of that period, was one conducted by G.E.Dalrymple, who penetrated the coastal country north of Rockhampton as far north as the Burdekin.
