Australian Canola Crop In Doubt

Slightly old, but I stumbled across this article in ABC Rural about the costs of oil on farming. One key passage here reads
With winter plantings due to start in the next month, Mike Chaseling from the Emerald Group says it is a tough time for growers, with a raft of rising costs.

He expects less canola to be planted, with many farmers turning back to livestock.

With canola -- aka rape -- forming one basis crop for biodiesel, one wonders whether the energy inputs to biodiesel aren't too high to support it on an ongoing basis without petrochemical inputs. The economists tell us that EROEI doesn't tell us anything beyond what a conventional economic cost/benefit analysis would give us; is it possible that they are in some way equivalent, at last?
