I suggest you read what I write (which isn't much) before accusing me of not understanding basic economics.
(1) But you don't understand it. If you did you wouldn't have made that argument.
The basis of your argument was that there is there is a fixed amount of resources, more people means that "there is less resources to go around" and hence the standard of living goes down.
It is totally fallacious. That is not at all how a nation's standard of living is determined. It has little to do with the amount of natural resources within some arbitrary political boundary.
Furthermore your argument assumes that Australians cannot utilize foreign resources, like foreign labour, foreign goods, foreign investment, etc.
(2) I wasn't arguing that everyone should breeding like mad. I was arguing for the removal of governmental restrictions on the free movement of persons.
Your argument also assumes that under free imimgration the world population would be higher than what it would be under government restrictions on movement. Oh wait no, nvm this, your world is only Australia, and you argue that we should ignore completely the welfare and human freedoms of all 6 679 000 000 non-Australians as if they don't exist or they don't matter.
What about the welfare of non-Australians? Why not care about them? Why care only about those who are Australian? Why doesn't the welfare of non-Australians come into the equation?
Because we are more important.
