Hundreds of employees were evacuated on Tuesday from a Canberra-based department of Australia's Foreign Affairs and Trade after a suspicious package was found in the canteen of the building, which is close to Parliament House.
Police are investigating the package found in the staff canteen area at lunchtime. In a statement, police said it has cordoned off the area as a standard safety precaution.
"Evacuations are underway at DFAT and road closures implemented. Members of the Australian federal police, bomb response team are in attendance," the statement said.
Media reports said that hundreds of public servants were evacuated from the building which is close to Parliament House and police blocked traffic on state circle.
A childcare centre is also attached to the building which is also closer to the Parliament building. Some staff claimed that a backpack had been left unattended in the canteen and the building was evacuated about 10 minutes after it was noticed, reports said.
On Tuesday, heavily armed police stormed the Lindt Chocolate Cafe in Sydney ending a 17-hour siege in which the captor and two hostages were killed.
