Australian Foreign Minister Stephen Smith said the day the three Bali bombers were executed was a sad day for Australians.
"It's not a day that fills us with any joy or with any celebration," he told ABC Television. "My first thoughts are for the families of the victims of both the Bali ombings, it's just in my view a terrible reminder of a terrible, horrible event that occurred to family members."
He said Australia, which opposes the death penalty, will press for an international moratorium on capital punishment.
The three Bali bombers -- Imam Samudra, Amrozi Nurhasyim and his brother Ali Ghufron -- were executed early Sunday morning for their 2002 nightclub bombings on the resort island of Bali that left 202 people dead, many of them foreign tourists.
The dead included 88 Australians, 28 Britons and eight Americans - most of them revelers fleeing the first blast.
Brian Deegan, who lost Hisson Josh in the bombings, said he felt "a whole lot of mixed emotions" with the news of the executions of .
He staunchly opposes capital punishment and worries about revenge attacks in the wake of the executions.
"There's no shortage around the world of persons that are prepared to commit suicide to acieve a result," he said.
But Sydney resident Maria Kotronakis said she was very happy after the execution of the bombers who helped kill her two sisters and two cousins.
"We're very happy ... we've waited a very long time for this and this is our justice," Kotronakis told CNN. She said the bombers hd "lost their rights to anything that's human."
