Hello,
Thanks for taking the time to engage with me on this one. Firstly the query revolves around another party, I am an Australian Citizen and I am currently involved in a vexatious legal matter with an individual who is already outside of his 457 conditions having been dismissed from his original employer, remained unemployed for about 4 months and then obtained employment with another firm in a similar but not identical position. Concurrent to his original employment he set up a number of companies under his ABN registered entity.
As I am of course not privvy to his visa application I am unable to answer your questions other than to say that for item 1; it is questionable. For item 3 I would say a definite 'no'. The companies he has set up are not related to the role he was employed for.
Therefore I am hopeful that there is a broad enough restriction under law that would allow me to report his dealings to the Immigration Department in an effort to expedite a decision on this status.
