The debate is not about immigration and its benefits. We all believe in them — Australia is a migrant nation. The debate is not about multiculturalism and it’s not about the source of migrants. The debate is about whether immigration should be running at very high levels. It’s about whether we end up with a population of 36 million in 2050 in contrast to the previous expectation of 28.5 million.
There are strong economic arguments against this immigration surge. Immigration worsens skills shortages. The tradesman who’s recruited for a specific job arrives with his family. Immigration adds more to the demand for labour than it contributes to the supply. The Productivity Commission Research Report (2005) The Economic Implications of an Ageing Australia made clear migration does not reverse the ageing of the population.
