Your theory that everyone is treated the same does not hold. Do you have evidence to support this or is it an assumption that you are making?
Aussies look after Aussies first?? If that is so, then DIMIA should state that very clearly in their promotional language. No misleading statements! If no one ever raises this issue, some migrants will keep on suffering which is an injustice.
According to the Aussie Racial Discrimination Act of 1975 reflecting the International Convention on the Elimination of all forms of Racial Discrimnation (CERD), Australia (which is a signatory) : "It is unlawful for a person to do any act that involves a distinction, exclusion, restriction or preference based on race, colour, descent or ethnic origin which has the purpose of nullifying or imparing the recognition, enjoyment or exercise, on an equal footing, of any human right or fundamental freedom in the political, economic, social, cultural or any other field of public life".
So the law is there. It is just not enforced!
By the way- I have a very good job. I started this thread coz I have seen migrants getting a raw deal.:D
