Natural science collections are vast treasure troves of biological data which inform current research and conservation.

Alongside bird skins, nests, eggs and DNA samples sits a magnificent collection of rare books, illustrations and images which charts the history of amateur and professional ornithology in Victoria.

Whilst the big names such as John Gould (1804–1881), are represented, the very local, independent bird observers such as John Cotton (1801-1849) and Archibald James Campbell (1853–1929) made some of the most enduring contributions.

The collections also document the bird observers themselves; their work in the field, building collections, their efforts to publish and the growth of their ornithological networks. Captured within records are changes in ornithological methods, particularly the way data is captured and published.

However the data itself remains as relevant today as it did when first recorded, 160 years of collecting gives us a long-term picture of birdlife in Victoria through space and time.

CULTURAL WARNING: Aboriginal and Torres Strait Islander users are warned that this material may contain images and voices of deceased persons, and images of places that could cause sorrow.

Continuing the practice of making and wearing possum skin cloaks has strengthened cultural identity and spiritual healing in Aboriginal communities across Victoria.

Embodying 5,000 years of tradition, cultural knowledge and ritual, wearing a possum skin cloak can be an emotional experience. Standing on the barren escarpment of Thunder Point with a Djargurd Wurrong cloak around his shoulders, Elder Ivan Couzens felt an enormous sense of pride in what it means to be Aboriginal.

In this story, eight Victorian Elders are pictured on Country and at home in cloaks that they either made or wore at the 2006 Melbourne Commonwealth Games Opening Ceremony.

In a series of videos, the Elders talk about the significance of the cloaks in their lives, explain the meanings of some of the designs and motifs, and reflect on how the cloaks reinforce cultural identity and empower upcoming generations.

Uncle Ivan’s daughter, Vicki Couzens, worked with Lee Darroch, Treahna Hamm and Maree Clarke on the cloak project for the Games. In the essay, Vicki describes the importance of cloaks for spiritual healing in Aboriginal communities and in ceremony in mainstream society.

Traditionally, cloaks were made in South-eastern Australia (from northern NSW down to Tasmania and across to the southern areas of South Australia and West Australia), where there was a cool climate and abundance of possums. From the 1820s, when Indigenous people started living on missions, they were no longer able to hunt and were given blankets for warmth. The blankets, however, did not provide the same level of waterproof protection as the cloaks.

Due to the fragility of the cloaks, and because Aboriginal people were often buried with them, there are few original cloaks remaining. A Gunditjmara cloak from Lake Condah and a Yorta Yorta cloak from Maiden's Punt, Echuca, are held in Museum Victoria's collection. Reproductions of these cloaks are held at the National Museum of Australia.

A number of international institutions also hold original cloaks, including: the Smithsonian Institute (Washington DC), the Museum of Ethnology (Berlin), the British Museum (London) and the Luigi Pigorini National Museum of Prehistory and Ethnography (Rome).

Cloak-making workshops are held across Victoria, NSW and South Australia to facilitate spiritual healing and the continuation of this traditional practice.
