Can you identify where this was painted?

Head of the Mitta Mitta, eagle's view of the mountains, Eugène von Guérard, 1879.
'This painting, depicting the head of the Mitta Mitta River near Omeo, looks towards Mount Wills, named after the explorer William Wills of the ill-fated Victorian Exploring Expedition. The Austrian-born painter Eugène von Guérard, who was in Australia between 1852 and 1881, is considered one of the most important landscape painters of the 19th century.'

A friend of mine would like to find out where the artist stood to see this view, if it exists at all. There may be some artistic licence involved as with many landscape paintings. The Mitta Mitta river is also called Big River and many old accounts of this river call it this from the source near Spione Kopje. Most of the old locals still referred to it this way but old maps also show it to be Big River to the confluence of the Cobungra and then the Mitta Mitta. I had thought this painting could have been done from a position near Anglers Rest but there is no visible water depicted in the painting and views from this area would show the river quite large. It would be easier for someone to access Anglers Rest in 1879 but Spione Kopje would be a little harder.
