The Kosovo refugees that were bought here during their war is a good example of national and governmental will in action.I get what you're saying, but it's not entirely accurate.
One of the key things I worked on personally when I was in the Settlement and Multicultural Affairs portfolio in Canberra was the 'surge' intake of Syrian and Iraqi asylum seekers following the escalation of hostilities there in 2015.
The Commonwealth Government (under Tony Abbott, no less!) announced an additional intake of 12000 Syrian/Iraqi refugees, on top of our existing annual intake of 13,000~.
It worked well because it was funded well. It demonstrated that our intake process are perfectly capable of being fluid instead of rigid.
Nothing is impossible for a nation state like Australia, you just have to be willing to pony up the resources to do it.
