According to a new economic analysis, there is no evidence to support negative perceptions of the impact of migration.
On the contrary, migrants are up to three times more likely to start a business or win a Nobel Prize, and up to four times more likely to lodge a patent for a new invention.
The findings were revealed at a conference in Sydney early last month, attended by nearly a thousand people from more than 30 countries.
The report, Migration and the Economy: Economic Realities, Social Impacts and Political Choice, looks at discrepancies between public notions of migration and the actual trends.
Analysts at the conference said deterrence and detention have become key pillars of immigration policies around the world, but argued that this approach doesn't work.
Some said blatantly that encouraging negative perceptions of migrants and refugees served no purpose other than to attract support in political campaigns.
Speaking of refugees in particular, Paris Aristotle, of the Survivors of Torture Australia, said the international community needs to think differently about how they manage people fleeing war and hardship.
