Last year, on the ninth anniversary of his father's death, Grant Sexton took his new baby boy to Kings Park.
The 28-year-old Perth resident has weathered some difficult times since 2002, when he received the terrible news that his dad Lee Sexton had been killed in the Bali bombings.
But that day in 2011, with his seven-month-old boy and wife Mel waiting in the car while he visited the memorial to the 88 Australians lost, was the hardest.
It was when he realised his son Evan would never know his grandfather.
"My wedding day was hard," Mr Sexton said. "The birth of my son was hard as well.
"But probably the hardest day was last year. We went up to Kings Park on the anniversary. It was the first year since Evan had been born.
"It was quite difficult knowing that he was never going to see him."
The damage and pain from those terror attacks 10 years ago is still being inflicted on the loved ones of those lost.
"The people that have been affected are never going to forget it," Mr Sexton said.
Speaking for the first time, Mr Sexton and his sister Clare yesterday paid tribute to their remarkable father.
"Dad was just a really good bloke," Mr Sexton said.
"He just loved his family and loved his sport, especially golf.
"He was a funny guy, always laughing or joking. He was just a really good dad."
Mr Sexton was 18 when his 45-year-old father went on a holiday to Bali with his mate Andrew Dobson, 40. Neither of them, who had both separated from their wives, would return home alive.
The then-teenager was house-sitting his father's home with his girlfriend Mel, whom he married in 2007, when the bombs went off.
The couple were visiting a friend the following morning when news of the tragedy began to flash on the TV.
At first, he hadn't been worried about his dad, who worked as a sales representative for a printing company.
"I didn't think he'd be out in the nightclub scene," Mr Sexton said.
But as time ticked by, and he and his then 16-year-old sister Clare heard no news, the fear set in.
"We didn't hear anything from Dad," he said.
"I started to think, 'this is pretty serious'."
The days turned into weeks and still there were no news.
"It was strange but you just wanted to have some closure, to confirm he'd been killed, or that they'd found him," he said.
"If they'd never found anything it would have eaten away at me for ever."
Lee Sexton's remains were eventually identified using DNA.
"When the police did come around to my mum's place, she called and she said, 'do you want to come home, I've got some news'," Mr Sexton said. "I knew what she was going to say."
He said he and his wife and son would be in Bali this week to commemorate the 10th anniversary of the bombings.
Though his little boy would never meet his grandfather, Mr Sexton said he would do his best to make sure his son knew him."It's important he knows a little bit about what happened to his grandad," he said.
