You make a very good argument for shutting down all immigration to this country. I've been making this argument for ages, endless population growth is not sustainable, just because other countries have overpopulated themselves is not a good reason for us to do the same. Their overpopulation has lead to people wanting to flee and come here ... and then continue their old ways and turn Oz into a crap hole like they left.
We need to learn to grow our economy without growing the population, living sustainably is the only way we survive long term
