Major items traded across the continent included marine and freshwater shells, notably the engraved pearl shell and baler shells (Melo diadema). There was also coloured ochres and clays, resin and gums, fish-hooks, obsidian, axe stone (probably the heaviest item traded along with lighter grinding stones (quorns) like those used to prepare Nardoo (Marsilea sp.) in Arnhem Land) along with pichuri, fibres and strings, special timbers and firs – mainly pelts of possum, kangaroo rat, wallaby and kangaroo. The women, especially, would trade in mats, ornaments, baskets, net bags and digging sticks. For hunting and warfare there were spears and spearpoints, shields, boomerangs, and throwing sticks. 
Unusual goods from distant places were always popular. Sometimes particular resource sites, like those containing ochre, would be controlled by one or a few families. In the Torres Strait, where island gardens sometimes produced an excess of storable root vegetables like yams, there would be trading with clans on the north Australian coast.
At the time of European settlement a quarry on Mt Wilson 70 km to the north of Melbourne was being mined by Wurundjeri man Billibellery and stone axes crafted, the axes from the site used to peel off tree bark used in the construction of canoes. Some of these axes were recovered from Swan hill 300 km to the north. At Melton Mowbray in southern Tasmania the chips and debris of a chert quarry covered an area of about 4,000 m2
As nomads any material goods, including food, were an additional weight to carry and so little was produced in excess of daily needs. This maximised travel efficiency and minimised the social organisation necessitated by additional items needed for daily life and trade. Australian Aboriginals did not use camels, horses or any means of transport, not even the wheel: they walked. As a people the First Australians, to get to Australia from Africa, had walked the full distance, arriving about sixty thousand years before triumphant Enlightenment Europeans sighted the continent from their ships. Resources were all obtained from the land and land management was carried out by walking the tribal territory. Adjacent tribes would meet and councils would be held for the organisation of marriages, trade, and the exchange of skills, songs, dances, and ceremonies – but walking was what life was all about along the trading trails that linked waterholes.
Dreaming paths & trading routes
Aboriginal trade routes, based on the movements of Dreamtime ancestors, were known as Dreaming paths or trails which were also linked through storylines and the Dreaming: their storylines passing through Aboriginal nations and creating connections across the length and breadth of the continent. When trade was expected fires were sometimes lit on high ground to both guide the trading parties and let people know that traders were expected: they were only extinguished when trading was completed.
Trading routes followed natural features of the land,especially those that would provide resourcesfor travellers on their journeys such as waterways, valleys, ranges and the coast.
Dreaming paths guided people along trails to resources, especially waterholes, soaks and meeting places. These were the routes along which goods and knowledge would pass: they were sacred and ceremonially sanctioned routes that featured in songlines, dances and map paintings. Stories about them would include mention of the geological formations and other features encountered on the routes as they had been created by the spirit ancestors in the Dreamtime and in this way ‘storylines’ or ‘storystrings’ etched the trails into aural history for future travellers. These paths were the trade routes that criss-crossed Australia and passed on the Dreaming and cultural values. Desert people walked for months distributing ochre. Explorer Giles observed among the few possessions of a central Australian, a marble from Adelaide, a pearl shell from the north coast, possibly sourced to Malaysia. Historian Bill Gammage has reported Kimberley and Torres Strait shell passed through the Great Sandy Desert to the Nullarbor, and shells from Papua found in western New south Wales.
Aboriginal knowledge of the land and the dreaming paths was harnessed by explorers, surveyors, troopers, stockmen and plant collectors who could take advantage of the watering places that occurred at intervals along the routes and steer a way through neutral territory and along the margins of tribal territories. Among those who took advantage of Aboriginal skills were: Flinders, Mitchell, the Jardines, Kennedy and Hodgkinson as well as stockmen and others who used Aboriginals as trackers, stockmen, guides, scouts and interpreters and as a means to forestall any potential conflict with native people. In this way dreaming paths became the European stock routes, drover runs and coachways … and eventually roads and major highways.
Among the better-known dreaming paths was one extending from the Kimberley to the Eyre Peninsula in South Australia along which passed pearl shell, red ochre, wooden dishes and other ornaments, and the Pituri Road with ramifications covering much of the continent from the Gulf of Carpentaria to southern and central; Australia, the most popular source being near Bedourie (its name possibly derived from the Aboriginal name for the plant) in SW Qld where it was processed, but extending into the Channel Country and Eyre Basin with a central meeting point for trade in autumn at Goyder’s Lagoon. Kerwin reports an estimated length of the road as 3,800 km challenging in extent and antiquity the famous European trade routes like the Silk Road, Incense Road and other ancient trade routes. Engraved pearl shells used in initiation ceremonies and rituals were also traded over 3,000 km from the Dampier Peninsula south to the Great Australian Bight and the Baler shell, Melo diadema, from Cape York south as far as Flinders in SA.
The Bundian Way is an ancient 265 km long track used mostly by Aboriginal people of the Monaro and of the South Coast used for thousands of years and linking the high country (the highest part of the Australian continent on Kosciuszko at Targangal) with the coast at Eden at Bilgalera (Fisheries Beach), Tullemullera (Twofold Bay). The track, a major route within a network of trails, used on the way to summer seasonal feasting corroborees on the Bogong moth (Agrotis infusa) at Nurudj Dujurund (Snowy River) in summer and springtime whale migration on the Eden Coast. Aboriginal artefacts have been found at key locations like the Monaro yam fields. Archaeological finds along the route have been made at Cascade Hut and the Tin Mine Hut indicating that settlers followed the paths and stations formerly used by the Aboriginals.
Early white settlers used Aboriginal guides along the track, exploring the land and looking for pasture.
Corroborees were an important part of Aboriginal communication and social organisation, helping to maintain kinship ties, conduct business and trade, share knowledge and resources or make alliances and settle disputes. The track is still a place for Aboriginal cultural activities. The Bundian Way is a Heritage Site of State Significance in New South Wales.
any early European explorers and stock routes followed the former Aboriginal trails which, in turn,followed the paths of the Dreaming ancestors. The following table gives a broad indication of what appears to have been some of the major trails.
|TRADE ROUTE||MAIN ARTERIES||MAJOR GOODS

Major trade routes (after Kerwin, pp.110–112)
Of special interest in Aboriginal trade is the fact that, because there were no domesticated animals to carry critical resources, trade was largely confined to ’luxury’ items enhancing cultural and social development but not its physical aspects which require bulk foods and materials.
Maps & navigation
Sand and other drawings were used by Aboriginal nations for many purposes one being their use as maps using lines, figures, circles and symbols representing features of the land, this being one of many ways of providing navigational instructions along with toas (ornamented sticks symbolically passing on all kinds of information including details of land ownership, acting as signposts and indicating where people were along with features of the land and where people could be found), message sticks and many other devices including song, stories and dance.
