Workers at Australia's major airports will face additional screening measures as part of a security crackdown.
The tighter controls come after authorities foiled an alleged terror plot to bring down a plane leaving Sydney Airport in July.
Australian baggage handlers and airport staff working in restricted zones will now be subject to random tests for traces of explosives.
Inspections will also be carried out on employees' belongings and vehicles.
The changes follow concerns raised by union and intelligence experts about the screening of staff, many of whom are on casual contracts.
The government said about 140,000 workers had access to secure zones in airports.
