Anzac Day 2017: Dawn breaks over Gallipoli service

Justice Minister Amy Adams has paid tribute to New Zealand soldiers at the Gallipoli Dawn Service on Anzac Day.

The number of attendees this year was significantly lower than in previous years, after the Government warned people to stay away due to terrorist threats in Turkey.

Only around 750 people attended, compared to more than 12,000 in the 2015 centenary commemoration.

For the sombre group gathering at dawn, their time there was short, with security officials restricting time spent on the peninsula to lessen the likelihood of an attack.

But the threats appear to have been unfounded.

"That the mission at Gallipoli failed in no way undoes what the Anzacs accomplished here or the great bravery and devotion to duty they displayed. In fact, it makes their suffering and achievements all the more poignant," Ms Adams said in her speech.

"And so every year, on this day, we gather at the rising sun to honour those first Anzacs. We remember their sacrifices. We remember the overwhelming odds. And we remember the dead - those who paid the ultimate price so we might enjoy our freedom.

"At Gallipoli, we fought a noble enemy, and in time they became our friends. We now stand shoulder-to-shoulder with Turkey, remembering our fallen men and the spirit in which they fought."

Ms Adams also attended an international service in Gallipoli on Monday, along with Australian Foreign Minister Julie Bishop.

In Australia, hundreds of thousands of people packed around war memorials across the country for Anzac services.

Security was stronger than ever at the services and with Australia's current national terrorism threat level as 'probable', it's a reminder that war is still raging in places around the world.

Australia's Governor-General Peter Cosgrove and Opposition leader Bill Shorten both attended a service in Papua New Guinea, while Prime Minister Malcolm Turnbull made an unannounced visit to Australian soldiers in Iraq and Afghanistan.

"It has been an honour to meet the servicemen and women in the Middle East, to thank the Anzacs of today for their service," Mr Turnbull tweeted.

And respect was paid from those at the bottom of the world, with Antarctica New Zealand sharing an image of a poppy in snow outside Scott Base.

"On this day, all around the world, we remember. Lest we forget," it wrote.

They joined the Australians in lowering flags at the bottom of the Earth to half mast, holding their own Dawn Service down on the ice.
