Fortunately we know Bill's not serious. The ALP opened the door to widespread use of 457's. The NLP found that the door could not be opened any wider so they knocked down the wall. Two parties of petty tyrants whose only worry is there might not be enough people to rent their investment properties and pay their parliamentary super. Neither party can answer the question of why you would start a high tech business in Oz with its high input costs, unfavourable tax regime, woeful internet services, craven 5-eyes membership, mass surveillance and mandatory airport strip searches. Any intellectual property the business developed would be stolen by one of our 4 eyed friends before the first code review.
A key problem for Australia and much of the free world is that STEM is being transformed from a driver of innovation and wealth to an overhead needed for surveillance, data mining and revenue protection. Under Bill's plan we will spend a lot of money to try and protect the boomers' legacy rather than moving forward and burying the bastards.
