The federal government has condemned deadly terrorist bombings at Turkey's largest airport, while urgently trying to establish if any Australians are among the dead or injured.
Foreign Minister Julie Bishop has extended Australia's sympathies to Turkey after what appears to be a co-ordinated terror attack at Istanbul's Ataturk Airport.
At least 50 people were killed and dozens more injured in Wednesday's suicide bombings.
The Department of Foreign Affairs is urgently trying to determine whether any Australians are involved.
Authorities had secured the area of the attack and closed the airport for 48 hours, Ms Bishop said in a statement.
Opposition immigration spokesman Richard Marles says the bombings are a reminder to Australia to be vigilant in the face of terrorism, which has become a feature of our lives.
Australia had some of the best terrorism agencies in the world, he told Sky News on Wednesday.
Cabinet minister Mathias Cormann labelled the attack "just another shocking example" of the uncertainty in the world.
Australians are being advised to reconsider travel to Istanbul and those already in the city are warned to remain attentive to their surroundings.
