Hi, I am looking to move over to Perth Australia in July next year to work in a Bar and Grill restaurant. I secured the job through a mutual friend and the owner over there accepted. I want to go for a total of 12 months. Although when I looked on the visa wizard on the Australian Governments website, the results showed that I would have to switch employers after a total of 6 months! Is there a visa that can get around this? THANKYOU!!
