In all the discussion about immigration, isn't the real problem about world population increases. Not to sound bad yet realistic, woman in poor countries need to have many children to support them in their old age. As long as we are talking about immigration restrictions without world population controls, such discussions are shallow. population increases are an economic market forces ideology. increasing populations creates residential and commercial building employment. what may be the problem is old religious, economic and social ideology based around available food resources, often solved with invented wars when ideologies become out of balance.

Immigration got us this,

"The video also contained a chilling message for its Australian audience, although it's likely it was recorded prior to the weekend's counter terror raids.

"I also send a message to my brothers, my beloved brothers in Islam in Australia," Prakash said.

"Now is the time to rise, now is the time to wake up...you must start attacking before they attack you."

Abbott is negotiating in Turkey to get our citizens, like this lovable chap, back to Australia; one wonders why.

There's not much that you can do against being stabbed, body armour is not an option for Australia's law-abiding citizens.

Is Mise,
Immigration also gave us Dr Tareq Kamleh.

So we until recently a member of an organisation which has declared war upon Australia was working in the WA health system, presumably in pediatrics? Tony Abbott and Bill shorten are asking us to trust Muslims simply because it's "racist" not to and asking us to believe that Islamic State is not legitimate, for flip's sake this man is a doctor and he has faith in the caliphate. What can liberal democracy possibly offer the majority of low IQ Muslim immigrants and their children if it can't keep a high IQ pediatrician?

I think the borders should be opened. Control should always be there, but open borders are a yes for me.

Dear Luca,

I agree, the borders to the continent of Australia should be open, but not the borders to Australian society and the benefits which accrue from it, including welfare, health services, housing and legal rights. Also, cities should be able to close their gates to immigrants if the population of that city so chooses.
