Commemoration ceremonies are being held on the Indonesian island of Bali to mark the first anniversary of the nightclub bombings that killed 202 people.
Surfers had their own way of paying their respects
After an official service attended by Australian Prime Minister John Howard, the focus shifted to the beach where surfers paid their own tribute to those who died.
A flotilla of surfboards laden with flowers paddled out to sea at sunset from Kuta Beach, near the site of the attacks.
Mr Howard thanked the people of Bali for their support, and said Australians "had learnt to control our anger and direct it towards identifying and punishing and bringing to justice those who perpetrated this terrible deed".
Australia lost 88 citizens in the attacks - more than any other country.
The names of all the victims - from 22 countries - were read out and tributes laid in a special pool of remembrance.
The service was predominantly Christian with local Hindu and Muslim elements and included prayers and readings.
Further remembrance ceremonies on Sunday include a Balinese service and a candle-lit vigil.
Throughout the weekend family and friends placed photos of loved ones or written messages on a fence where the Sari club - scene of most of the casualties - once stood.
"It's been a difficult year," said Angela Dark of Melbourne, Australia, as she placed flowers and a photo of her 32-year-old old brother Anthony Cachia at the site.
A year on, relatives are still grieving
"My brother was the one person in this life who understood me," she told Associated Press. "I miss him so much... the pain never goes away. I'm so angry, angry at the world."
Indonesia's senior security minister, Susilo Bambang Yudhoyono, reaffirmed his government's determination to hunt the terrorists down. "They have no place in our society," he told the mourners.
On Saturday, families of the 28 British victims held a special Christian church service on the island at which the Reverend Andrew Lake read out the names of the Britons who died.
Security has been tight for the ceremonies and police say thousands of extra officers have been deployed for the weekend's events.
Just before 2300 on 12 October 2002, a dark Mitsubishi minivan packed with 50 kilograms (110 pounds) of explosives pulled up in front of the Sari Club in Legian Street, Kuta.

An Indonesian man called Iqbal walked into nearby Paddy's Bar wearing a bomb concealed in a vest.
When his initial bomb went off, the crowd was sent scrambling into the street towards the Sari Club. Many who died in the second, much larger explosion were fleeing the first one.
The attacks have been blamed on Jemaah Islamiah, a regional militant group with alleged links to al-Qaeda.
