In April 2006 the Australian Government Productivity Commission published a report entitled Economic Impacts of Migration and Population Growth. The study included economic modelling of an increase in skilled migration of an extra 50,000 migrants per year, for 20 years, compared to the skilled migration numbers in 2004-05. Some of the conclusions were:

• economic gains accrue mostly to skilled migrants and capital owners (page 151);
• hourly wages will drop slightly under high immigration (page 161);
• the incomes of existing resident workers grows more slowly than would otherwise be the case (page 151);
• these results are consistent with research both in Australia and overseas (page 161); and
• environmental impacts are likely to impose a drag on productivity and living standards, but the details are “too hard” to quantify (page 122).

This is not a report by some racist group that wants to limit immigration to keep Australia white. This is not a report by some deep green environmental group that wants everybody to live in communes and wear jute shirts. This is the Productivity Commission. The Productivity Commission – primarily an economic research organisation.
