Wellwellwell.....the reason for allowing 457 Visa workers into the country has been supposedly about alleged skills shortages in the Industry. Have you been in a coma and not seen the hundreds and hundreds of recent retrenchments at Qantas and Forstaff? Where's the skills shortage now or are you still asleep? I reckon you'd see it differently if it was you being told you're finished whilst someone on a 457 remained doing your job.
Beat your chest as loud as you like.....your hypocrisy is louder!
