Large green circles in Australia what crop is this?

A British Broadcasting radio prog on farming made me look at this area -33.7117911, 148.584271 I found large green circle, I suspect they may have some sort of huge rotating irrigation system. How should they be mapped? alt text

I couldn't get my link to work. But Google Utube should do the job. Center Pivot Irrigation Systems

There's irrigation=pivot (~19k), more than irrigated=center_pivot (~150).

I think the circles will probably be seasonal, but in a this climate maybe a continual rotation ( no pun) of crops might be grown so maybe it should just mapped as arable land.
