There were never crops in the first place in the modern or even ancient sense.
Some tribes figured out that some tuberous plants can be replanted and will regrow after the tuber has been harvested and that's it.
Some may have understood how seeds work (that's debated) but at no point did Aborigines clear a plot of land to plant a particular species with seeds harvested last season.
This was a reason of total misunderstanding with the arriving Europeans, there was no way to lure them to help farm and get their share of the crops, it just wasn't on their map.
In contrast, Maoris just across the ditch understood both growing plants and raising livestock, and a mere decade after wheat and pork were brought from Europe they were widely growing both.
