Australia's economic success would be enhanced by having a national diaspora strategy and collaboration networks connecting with the one million Australians working overseas, and the 2.5 million foreigners who have studied in Australia.

Advance, the network for Australians working abroad, and for foreigners who have studied in Australia, hosted a roundtable discussion of leading directors, chief executives, start-up founders and financiers to discuss the PwC Advance report Out of Sight, Out of Mind? Australia's diaspora as a pathway to innovation, which shows that 69 per cent of a survey group of 1039 recently returned and expatriate Australians did not collaborate with businesses or colleagues in Australia, with 25 per cent saying this is because Australian-based peers weren't interested.
