Aboriginal author Bruce Pascoe grew up knowing only of his British ancestry. In his 30s he came to recognise that he also has Australian Aboriginal heritage and identified himself as Koori. Bolt objected to this apparent change in Pascoe's heritage following the success of "Dark Emu", a book written by Pascoe in 2014 that reexamines colonial accounts of Aboriginal people in Australia, and cites evidence of pre-colonial agriculture, engineering and building construction by Aboriginal and Torres Strait Islander people. Bolt suggested on his blog that Pascoe had succumbed to "the romance of the Noble Savage… the thrill of the superstitious".
