School kids need to be taught about our History, which includes how we fit in with the triumph of western civilisation over the rest of the world.

1. What features of our civilisation led us to develop such an inhospitable land as Australia, when the local natives barely could use fire;

2. The great advances that have been made since - introduction of agriculture, liberal democracy, technology, health, science, etc.

3. The risk of letting in too many backward people from those parts of the world that are still stuck in the Dark Ages and before such as Africa and the Middle East.
