Matthew Spencer was a journalist at The Australian for twenty years, with long stints running the Foreign News desk and as Opinion Editor. He has written for newspapers and magazines in Uganda and Kenya and been published in The Australian Financial Review and The Sydney Morning Herald.

He was born in Parramatta. The son of teachers, he lived with his sister Kate on the 320-acre campus of a boys' boarding school. Long summers on the largely deserted property while exploring the remnant bush with its tributary of the Parramatta River inspired this book. Black River is to be published by Allen and Unwin in June 2022. Matthew lives in Sydney with his wife, Ritu Gupta, and their three children.
