Australian Federal Police have been ordered to increase their presence at the nation's largest airports following yesterday's terrorist attacks in Turkey.
The Office of Transport Security - which regulates security at aviation and maritime hubs - briefed airlines and airports following yesterday's attacks at Istanbul's Ataturk International Airport, while the AFP enhanced its surveillance in the publicly -accessible areas of Australia's major airports.
Australia remains on a "high" level of alert, with ASIO maintaining its national terrorism threat level as "probable". 
"The Department of Infrastructure and Regional Development has encouraged industry participants to review security in public areas," a spokesman said.
"As aviation is a global industry, the government is also in contact with its international counterparts. This is so we can co--ordinate actions and work to ensure that the aviation sector does not grind to a halt as it is critical for our economy and way of life.
"We need to balance reactions to these tragic events with ensuring that we protect our freedoms." The Ataturk attack, which killed at least 36 people at the -arrivals area of the international terminal, prompted a leading border security experts to call for a review of security protocols around Australian airports and address the "soft underbelly" of departure and arrival halls.
Head of Border Security at the Australian Strategic Policy Institute John Coyne said the fact that the attacks occurred prior to sec-urity checks and in a crowded area demonstrated the need to reassess how passengers were processed at airports.
"There is no doubt that this is a tricky time for airport security but we must not have knee-jerk -reactions to this and try and push security borders further out at airports.
"After the Brussels attack, -people thought the best response was to push security measures out but all that does is move the target elsewhere," he said.
"What we need to do is address the reasons and the need to have so many people pooling in singular locations." It has been more than 10 years since the federal government commissioned British security expert John Wheeler to investigate the nation's airports.
The then Howard government committed $200 million to improve airport security after the review found policing at main airports was "inadequate and dysfunctional" and security systems "unco-ordinated".
Dr Coyne said while security protocols needed to be reviewed, it was imperative that a "commonsense" approach be followed on how security was applied at public areas in airports.
"After   September 11, there was a revolution in airport security. We don't need a revolution now but if this is what the new threat looks like, then we need to start thinking about how we can reduce the -concentration points of people at airport," he said.
