After his experiences as second with Ernest Giles, Tietkins took charge,
in 1889, of the Central Australian Exploring Expedition. He left Alice
Springs on the overland line on the 14th of March to examine the hitherto
unknown country to the north and west of Lake Amadeus. Late in the month
of May he discovered and named the Kintore Range, to the north-west of
Lake Macdonald, and ascended one of the elevations, Mount Leisler. During
the beginning of the next month he practically completed the circuit of
Lake Macdonald and discovered the Bonython Ranges to the south-east. On
his return journey, Tietkins corrected the somewhat exaggerated notion
entertained as to the extent of Lake Amadeus, as he passed through sixty
miles of country supposed to be contained in its area without seeing a
vestige of this natural feature. In after years he surveyed and correctly
fixed its location.

In 1874, surveyor Lewis, the gallant and tireless spirit whose
indefatigable efforts had pulled the Warburton Expedition out of the fire
took charge of an expedition equipped by Sir Thomas Elder to define the
many affluents of Lake Eyre. Starting from the overland line, Lewis
skirted Lake Eyre to the north, penetrated to Eyre's Creek, traced that
stream and the Diamantina into Lake Eyre, and confirmed the opinion that
the waters of Cooper's Creek as well as the more westerly streams found
their way into that inland sea. J.W. Lewis afterwards died in Broome,
Western Australia.

In 1875 the Queensland Government decided to send out an expedition to
ascertain the amount of pastoral country that existed to the westward of
the Diamantina River. It was placed in charge of W.O. Hodgkinson, who had
occupied a subordinate position in the Burke and Wills expedition. They
started from the upper reaches of the Cloncurry and, crossing the main
dividing range on to the Diamantina, followed that river down to the
southern boundary of Queensland, where it had been named the Everard by
Lewis. This portion was now well-known, and the tracks of the pioneers'
stock were everywhere visible. From the lower Diamantina, the party went
westwards, and, beyond Eyre's Creek, in good pastoral country, came upon
a watercourse which was named the Mulligan. This creek Hodgkinson
followed up to the north; and, not knowing that he had crossed its head
watershed, went on down the Herbert (Georgina) un
