Sure bro, keep dodging the real cause
Julian Assange was accused of rape in sweden.
Sweden's legal definition of sexual assault is VERY VERY loose, even encompassing 'sexual unfreedom'.
You can't compare crime statistics across borders, especially countries with very different legal systems and state security. Australia may have a higher reported rate of domestic violence than lets say Saudi arabia, but you can bet your ass that shit happens in S. Arabia all the time and goes unreported. Even the EU study on sexual assault in Scandanavia stated that there is a HIGH correlation with gender equality AND women reporting sexual assault (whole societal guilt thing).
We have an ENTIRE legal system on the basis of innocence UNTIL proven guilty. It's very insulting to the staff working at DIBP to tell them they aren't smart enough to assess whether or not a person is 1) a genuine refugee and 2) if they are a threat to the local community. So much BS and speculation whether 'someone can assimilate', I bet people said the same shit of your ancestors when they came to the country.
Generally, refugees are repatriated or have the option to go back to their homeland ONCE a event has stopped eg a war or genocide etc but many can feel unsafe. You bigots do realize the reason why people come all the way to aus is to escape the violence right? Putting them in detention centres and spending 50 mil to send 4 dudes to cambodia isn't exactly a solution.
