The government is considering cutting back on Anzac Day commemorations in Gallipoli next year because of the terror threat.
Veterans Affairs Minister Stuart Robert said the Gallipoli dawn service, one of Australia's most significant commemorative events, would remain.
But the government is consulting Turkey on whether the commemoration at Lone Pine, conducted during the Anzac Day morning, should be called off.
Mr Robert said Gallipoli centenary commemorations in April had passed off without incident but this was now the appropriate time to reconsider the approach for 2016.

"On reflection as there are risks to Australians and New Zealanders in attending multiple services, often over two days with little sleep with the Lone Pine service held in an exposed and isolated location, a review of the continuance of the Lone Pine service is appropriate," he told parliament.
Mr Robert said that review would be conducted in consultation with Turkish authorities.
Next year marks a number of significant anniversaries including the centenary of Australian involvement in their first battles of the western front.
Mr Robert said the western front was where Australian troops made their greatest achievements and suffered their greatest losses. There will be commemorations for the Battle of Fromelles and Pozieres in July.
Next year is also the 25th anniversary of the 1991 Gulf War and the 75th anniversaries of Tobruk, Greece and Crete.
The big event for 2016 will be the 50th anniversary of the Battle of Long Tan, Australia's single most costly engagement of the Vietnam War.
That will be marked on August 18 with a national service commemorating all who served in Vietnam.
Australia is also negotiating with the government of Vietnam for a small service to be conducted on the site of the battle in which 18 Australians died.
