People acting suspiciously in Australian airports will have to show identification to police under draft laws introduced to federal parliament.

Home Affairs Minister Peter Dutton said on Wednesday the new ID checking powers for Australian Federal Police would give officers the ability to make people leave the airport or ban them from flying for 24 hours if they did not comply with the check.

The legislation would ensure Australian aviation networks were some of the safest in the world, Mr Dutton said, adding that failing to comply with the checks could result in a fine of up to $4200.
