Last October, the Commonwealth Treasury released modelling intended to inform the design of the Government's carbon pollution reduction scheme. The modelling assumed net migration to Australia of 150,000 people a year through to 2050, which would result in an Australian population of about 33million by 2050.Australia's actual net migration in 2006-07 was 177,600, the highest on record at the time. The preliminary net migration figure for 2007-08 is 213,500. Because the Government further increased skilled migration numbers in 2008, it is likely net migration for 2008-09 will be higher still.
Those who are sceptical of calls for a sustainable population policy are also fond of pointing out that our modern, high-consumption lifestyle is the most pressing cause of our environmental problems. They are correct that we must tackle our high pollution and consumption levels and shift to a more sustainable lifestyle. According to the World Resources Institute, Australia's greenhouse pollution level of 26tonnes of CO2-e per person per year is double Germany's, six times China's and 11 times Indonesia's.
