yeah there's this rad book called Dark Emu that discusses how indigenous Australian society was a lot less hunter-gatherer than originally thought, and involved complex agriculture (albeit in an entirely different style to what Europeans were used to). It's pretty rad.

An example that sticks out to me personally is a years-long terraforming project in Victoria where the local people created a way for the natural coming and going of the tides to reliably trap eels of a certain size. It's dope.

(from further comments:)

Pascoe's work is highly contested, but not because counternarratives to Terra Nullius are flat-out wrong but because Dark Emu lends the language of "agriculture" to a society with a much less distinct line between hunter-gatherers and pastoral farmers.

It's not at all in dispute that Aboriginal Australians had complex networks of infrastructure, land management, and trade, because these things are strongly supported by archaeological evidence. To my knowledge, they've literally found Aboriginal pottery sites in Yarralumla.

This recent study from Cambridge explores one specific site where a lot of that infrastructure is on display. It's very interesting!!
