No names, no pack drill, but here's how to rort the 457 temporary worker visa system and whatever the government renames it.

Let's use an example of, say, refrigeration mechanics. This is a skilled area in demand. Yes, we increasingly want air-conditioning despite all the government backbenchers who don't believe in climate change.

There is an award for the job, but nobody with the skills works at the award wage – they're better paid thanks to the demand for their services.

So Dodgy Brothers Refrigeration advertises for refrigeration mechanics at the award wage and, surprise, surprise, receives no local applications.
