Too many PhDs, not enough tenured positions

In Australia, a post-doc applicant and myself are reporting an average of 145 candidates per position. This can be partly attributed to the 6000 researchers on a 402-category visa, which provides opportunity to experience our 'governance' on a the same remuneration as a casual McDonalds burger flipper receives. But the limited tenure has a further advantage for the institution, in that anyone who's reported misconduct has lost tenure and thus temporary residency.
