Q: What do you call the people who put the books back on the library shelves at your local university?
A: Doctor.
To extend that answer, the push for international students means that poeple who do the casual work at universities are massively overqualified. So why don't these people have real jobs? They could certainly get them, and in the areas these people know we are crying out for expertise.
The answer is Australia's immigration processes. Our immigration process is completely stuffed when it comes to encouraging people with knowledge and talent useful to Australia to remain here.
You can't get a job without a visa. Fair enough. But I know a few people on "interim" visas (the visa you get whilst Immigration is processing your residency application for the next 6-12 months). And despite the near inevitability of these people getting residency visas and the automatic re-issue of interim visas until that happens, an employer calling Immigration to ask about the job applicant's visa (as they must) is told it is only valid for three months. That is, the person is only good for a casual job.
To get a visa you must pass an "English" exam -- IELTS. If you don't pass your visa expires and you leave the country. And you though you were under exam pressure in Year 12?
You can imagine my shock when people I can readily comprehend fail the IELTS. One the the best seminars I've ever attended was given by a person who failed the IELTS the following month. How can that be? And why can't we simply attest to our experience of that person's excellent English skills?
Let's be blunt. Someone who has spent the last seven years of their life investigating water saving technologies is someone we need to keep. And by "keep" I don't mean stacking shelves, whether at libraries or supermarkets. These people are the salt of the earth -- they're bright, committed to Australia, they're already working hard (most studying and doing the jobs no Australian-born person wants). And we're making their life hell with petty bureaucracy. We're fortunate to have them; fortunate they want to stay after all we've put them through.
It's time Immigration ran a "reverse dob in" line. You could report people who should simply be immediately given a residence visa and welcomed to our country.
