A number of studies of human migration suggest that after initial colonisation of Australia around 45,000 years ago, these people remained largely isolated until the arrival of Europeans. In contrast recent studies have suggested that a wave of migration from India into Australia occurred approximately 4,230 years ago. However, a major drawback of these recent studies is that sequence data used was from modern indigenous Australians who were potentially admixed with Europeans. To address this issue we will sequence complete genomes from sub-fossil bones of ancient Indian and Indigenous Australian people and directly investigate this possible India-Australia connection.

许多关于人类迁徙的研究表明，在大约45000年前澳大利亚最初被殖民后，这些人在很大程度上保持着孤立状态，直到欧洲人的到来。相比之下，最近的研究表明，从印度到澳大利亚的移民浪潮发生在大约4230年前。然而，最近这些研究的一个主要缺陷是，使用的序列数据来自现代澳大利亚土著，他们可能与欧洲人混在一起。为了解决这个问题，我们将从古代印度人和澳大利亚土著人民的亚化石骨骼中测序完整的基因组，并直接调查这种可能的印度和澳大利亚的联系。
