Michael has worked for the past 20 years in Aboriginal history, preparing expert reports for NSW native title claims, recording community genealogies and writing regional histories for local councils and government authorities. More recently, he has recorded oral histories for the State Library of NSW and National Library of Australia. He is the author of Pathfinders, A History of Aboriginal Trackers in NSW, published in 2020. A website of the same name went live in 2016, the result of a collaborative project with NSW Police and the descendants of trackers.
