Tests carried out at Heritage Victoria recently confirmed the artefacts originated from south-eastern Australia.

The weapons include intricately carved parrying shields, spear throwers and clubs.

They are believed to have been crafted and used by the Djargurd Wurrung tribe, which occupied land stretching from Mount Emu Creek to Cobden and to the west of Lake Corangamite.

Heritage centre president Bob Lambell said the results were an exciting development.

"In our existing collection that we've had for a very long time, there is one or two weapons almost identical (to the weapons in the newest collection)," he said.

"It's been very valuable feedback because we've had no idea if they were local or national".

The latest collection was donated by Camperdown's Jenny McPherson earlier this year, after previously being stored under a bed for 15 years. A collector is believed to have given the items to a Dr William Waugh Hope of Birregurra in the late 1800s.

Dr Hope passed them on to his son, Marsden, who then gave them to Ms McPherson in the early 1960s.
