An annual national survey by the philanthropic Scanlon Foundation has found that while four in five Australians see benefits to immigration, a rising number think the intake is too high, up from 37 per cent last year to 43 per cent in the 2018 survey.
That's the highest it's been since 2010, when the number concerned the rate was too high peaked at 47 per cent following the Coalition's vow to cut migration after Kevin Rudd's speech supporting a "Big Australia".
Despite this, the 2018 Mapping Social Cohesion survey finds more than half of Australians consider the current intake of migrants either good or too low.
The survey canvassed the views of 1,500 randomly chosen Australians on issues such as social cohesion, immigration and population issues.
Researcher Andrew Markus, from Melbourne's Monash University, says, despite concerns about population management, 82 per cent of those surveyed believed immigrants improve Australian society.
