Warburton described the country as dry and arid; but Hack's account was distinctly favourable.

Of the two men, however, it is most probable that Hack possessed the more experience and knowledge of country, and, moreover, Time, the great arbitrator, has endorsed his words.
The year 1857 saw much exploration done in South Australia.

One party, consisting of Swinden, Campbell, Thompson, and Stock, at about seventy miles from the head of Spencer's Gulf, found good pastoral country and a permanent water-hole called by the natives Pernatty.

to the north they came upon Campbell's former discovery of the Elizabeth, but their provisions failing they were forced to return.
A month afterwards Swinden started again from Pernatty.

North of the Gawler Range he found available pastoral country, which became known as Swinden's country.
