Hear from historian Stephen Gapps how Aboriginal people used the rivers, creeks and waterways from Pittwater to Windsor. At ‘Gentlemans Halt’ we stand on country evoked in ‘Benevolence’ by indigenous writer Julie Janson about the Hawkesbury River in the 1830s. Cruising upriver we trace hidden stories in the landscape of bolters, bushrangers and early river traders with expert storyteller Max Burns McRuvie.
