The Ngaro are an Australian Aboriginal group of people who traditionally inhabited the Whitsunday Islands and coastal regions of Queensland, employing a seafaring lifestyle in an area that archaeologically shows evidence of human habitation since 9000 BP.
As of 2020[update], the Traditional Owner Reference Group consisting of representatives of the Yuwibara, Koinmerburra, Barada Barna, Wiri, Ngaro, and those Gia and Juru people whose lands are within Reef Catchments Mackay Whitsunday Isaac region, helps to support natural resource management and look after the cultural heritage sites in the area.
This was only possible due to their development of barbed harpoon technology that enabled the Ngaro to kill their prey by exhausting them rather than bleeding them to death, which would attract sharks to compete for the catch.
The Ngaro traded with the mainland, and their artifacts such as baler shells for carrying water, and juan knives fashioned from rock at South Molle, which had one of the largest of such pre-European quarries in Australia, found their way a good distance inland and far up the coast.
The painting of a hashed oval shape is often presumed to be a sea turtle shell, a prominent food source for the Ngaro and Aboriginal people of the mainland.
