Sixty per cent of all Australians say they would be concerned if a relative married a Muslim, according to a new university research project tracking attitudes to Islam.

It also found that more than a third of people would not object to Muslims being searched more thoroughly at airports than other people.

And a quarter would not be fazed if all anti-terror efforts were focused exclusively on Muslims.

The study comes on the heels of a poll last week that found half of all Australians support a ban on Muslim immigration.
