Forest raven = corvus australis?

Here’s an amusing taxonomic quandary… In 1781, Latham writes of “south-seas raven” based on specimen collected from Cook’s 3rd voyage – he reports it’s from the friendly isles (Tonga) Gmelin gives it the name Corvus australis in 1788. Gould adopts the name in his 1865 handbook Matthews says name is preoccupied and drops it Stresemann in 1950 researches specimens collected on Cook’s 3rd voyage and opines that the specimen was collected in Adventure Bay (Tasmania) …sooo……should the correct name of the forest raven be Corvus australis Gmelin?
