Editing Collet Barker (section)

===South Australia===
In 1831, on the recommendation of [[Charles Sturt]], who had visited the shoaled mouth of the [[Murray River]] the previous year, Barker was sent to explore the east coast of [[Gulf St Vincent]] in [[South Australia]] to see if another channel from the Murray entered the sea there.

On 13 April 1831, Barker and his party arrived at [[Cape Jervis (headland)|Cape Jervis]] on the ''Isabella''. He examined the coast as far north as present day [[Port Gawler, South Australia|Port Gawler]] and found that there was no channel. Barker encountered the [[Onkaparinga River]] on 15 April. He then explored the ranges inland, north of the present site of [[Adelaide]], and climbed [[Mount Lofty]] Ranges (without reaching the summit) where he sighted the [[Port River]] inlet, [[Barker Inlet]] and the future [[Port Adelaide]], his most important sighting. He then moored ''Isabella'' near present [[Yankalilla Bay]] and went overland to explore the area around [[Lake Alexandrina (South Australia)|Lake Alexandrina]] and [[Encounter Bay]].<ref>{{cite web | url=https://adelaideaz.com/articles/explorer-collet-barker--known-for-indigenous-empathy--killed-in-possible-mistaken-link-to-sins-of-kangaroo-island-sealers- | title=Explorer Collet Barker, known for indigenous empathy, killed in 1831: Possible link to sins of Kangaroo Island sealers }}</ref>
