They left Cork station on the Diamantina, and kept a north-west course through the untraversed country between that river and the Georgina, or Herbert, as it was then called.
They then crossed the border into South Australia, and struck the creek which Buchanan had found, and to which the name of Buchanan's Creek was now given.

Leaving this creek at the lowest water, the party struck north, and, after finding two large but shallow lakes, came, in the midst of most excellent pastoral country, to a fine lagoon which they named the Corella Lagoon.

The trees on the banks of this lagoon, which was about four miles long, were at the time of the visit white with myriads of corella parrots; hence the name.

Some three hundred natives were assembled at this lagoon to celebrate their tribal rites; but they showed a friendly disposition.
From the Corella Lagoon the expedition proceeded north and discovered a large creek running from east to west.

It proved to be one of the principal creeks of that region, and was named Cresswell Creek; and a permanent lagoon on it was named the Anthony Lagoon.
