In 1854 Austin made a lengthened journey to the east and northwards,
from the old settled places of Western Australia, and in 1856 Augustus
Gregory conducted the North Australian Expedition, fitted out under
the auspices of the Royal Geographical Society of London. Landing at
Stokes's Treachery Bay, Gregory and his brother Frank explored
Stokes's Victoria River to its sources, and found another watercourse,
whose waters, running inland, somewhat revived the old theory of the
inland sea. Upon tracing this river, which he named Sturt's Creek,
after the father of Australian exploration, it was found to exhaust
itself in a circular basin, which was named Termination Lake.
Retracing the creek to where the depot was situated, the party
travelled across a stretch of unknown country for some two hundred
miles, and striking Leichhardt's Port Essington track on Leichhardt's
Roper River, his route was followed too closely for hundreds of miles
until civilisation was reached. My friend Baron von Mueller
accompanied this expedition as botanist, naturalist, surgeon and
physician.

Soon after his return from his northern expedition, Gregory was
despatched in 1858 by the Government of New South Wales to search
again for the lost explorer Leichhardt, who had then been missing ten
years. This expedition resulted in little or nothing, as far as its
main object was concerned, one or two trees, marked L, on the Barcoo
and lower end of the Thompson, was all it discovered; but,
geographically, it settled the question of the course of the Barcoo,
or Mitchell's Victoria, which Gregory followed past Kennedy's farthest
point, and traced until he found it identical with Sturt's Cooper's
Creek. He described it as being of enormous width in times of flood,
and two of Sturt's horses, abandoned since 1845, were seen but left
uncaptured. Sturt's Strezletki Creek in South Australian territory was
then followed. This peculiar watercourse branches out from the Cooper
and runs in a south-south-west direction. It brought Gregory safely to
the northern settlements of South Australia. The fruitless search for
it, however, was one of the main causes of the death of Burke and
Wills in 1861. This was Gregory's final attempt; he accepted the
position of Surveyor-General of Queensland, and his labours as an
explorer terminated. His journals are characterised by a brevity that
is not the soul of wit, he appearing to grudge to others the
informati
