".... a massive swing of arable land in the southern agricultural zones moves from pastures, hay and feed grain production to wheat and canola"
Given my own experience in agriculture, I can't see that happening for the very reason that rotations, diversity of production and land suitability will only see marginal change to volumes.
Anyway if the Numpties on the Left of politics get their way we will see a major collapse in Australia's agricultural production.
