Its about nationalism, its about Australian citizen jobs. A 457 Visa is for a skill shortage which does not exist. I'm sick of people jumping on the racist, xenophobic discrimination train every time something is mentioned about any 457 guy/girl. No one here has mentioned race. The only thing we all care about is jobs and doing the right thing by Aussies.
As for JHAS, talk to anyone at Virgin Tech Services, talk to anyone at Jetstar or Qantas in Tulla. The quality is terrible. Simple short cuts brought around by idiot management and poor quality in recruitment.
You are an idiot if you think they pay $30/hr in places like Singapore or Malaysia. That is not how they make there money.
