Mary, Waldecks currently have Yacon for what appears to be much less than the private sellers & they are healthy plants.

Yes it can. There is currently an advertisement on Gumtree for Yacon plants in the Joondalup area. You may find them in green grocers or whole food stores that sell produce.

I live in Albury. I have been growing them here for about 6 years. We have not got many left. We have given many away. We have left them for a couple of years. Due to illness. But this year we plan to dig them out, and replant them. We have very hot days and frosty days. They do not mind. But they are growing behind a wall. With a fence on one side. So I guess it is some what sheltered.

You could plant sprouted tubers in October or November in your cooler climate. It would be ready for harvest in April or may but you could carefully take some tubers earlier.

Diggers in Melbourne and Green Harvest in SE Queensland list it. There will be others. It is listed on Gumtree also, have a look there.
