Australia should aim to keep the working-age population stable

Australia’s overall population should stay within ecological limits.
Migration is needed to maintain the current working-age population level due to the declining birth rate, emigration and as existing workers move to retirement. This would mean about 100,000 migrants are needed each year.
Migration and housing
Australia’s housing affordability problems are due to our tax settings, not migration.
House construction has exceeded the rate of migration in the last decade but the price has still gone up – so migration is not to blame. (Australia Institute)
Migrant construction workers are critical in the housing industry.
We also have a declining birth rate so the population would shrink without migration.
Migration and health
The healthcare and aged care systems are full of migrant workers, and more are needed. Cutting back on migration of skilled medical workers would severely hamper provision of health services.
Non-racist immigration
We oppose racist anti-migrant policies proposed by those who want to go back to the White Australia Policy and deport everyone else.

Migration and the economy
Economic progress should be measured in terms of well being not GDP.
We should use measures such as a Genuine Progress Indicator to capture changes in quality of life rather than just the gross spending on things.
Encouraging emigration
Emigration of people who are opposed to progressive, scientific & secular government should be encouraged with grants to offset their relocation costs.
