They used it as an instrument of fear very successfully during the Tampa incident, but now the Liberals, in a desperate attempt to lift popularity among a working class that has rebelled against Liberal IR laws, are having a go at Africans, claiming that they will reduce the number of Africans coming into Australia because they were having problems integrating.
First of all, why integrate? Most marriages end in divorce, most people don't save up enough to retire, most people don't get into university, and so on. If you are forced to do what the majority is doing, you are going to turn out to be a loser.
Another problem I have with this idea is that it profiles people based on nationality or continent. It may be that African people as a whole are less likely to integrate, but does that mean all Africans should be punished for it? Some say yes. But consider this. Men are more likely to commit crime than women. Therefore, should all men spend one year in prison? Poor people are more likely to be involved in crime than rich people. Should poor people be locked up? Suppose we wanted hard-working people in Australia. Billionaires are more hard-working than non-billionaires. Therefore, if you are a millionaire, does it mean you should not be allowed in?
Judgment needs to be made at an individual level otherwise anyone can be accused of anything.
