Like other 'guests' on the internet, I support wholeheartedly the development of such programmes which seek to address the dubiety of history. Western Australia is a long way from the Eastern centre, and the events documented in 'Frontier' also happened in this part of the world, often, as in the case on Neville's project, under the cold logic of bureaucratic efficiency. It is essential to bring this historical frame into the 20th century, and to localise the events so that it can never be claimed that this happened too long ago and too far away. The challenge for all Australians is to investigate and test ways of understanding and reimagining our relationships to each other, as Australians with different and often painful histories. Frontier' is an important and essential step in that direction.
Ethnicity is more a matter of sentiment than of genetics.
Your presenters should make such distinctions clear and not confuse these two matters of sentiment and genetics.
