Bill Mollison really puts the Gardening Australia permaculture
'attempts' to shame.

Gardening Australia seems to deal mostly wih the urban block, whereas
Bill was dealing with rural land.

I also find GA a bit more ecologically responsible. BM didn't seem to
consider ecological impact when some of his recommendations; e.g.
pampass grass, blackberries, etc. Yes, the information was known in his
time.
