Whether it's through walking, talking or computing, Bruce and Denise Morcombe feel they are taking enormous strides in protecting children from sexual abuse.
The couple will do all three as they mark 'Day for Daniel', a national event in memory of their son who was abducted and murdered almost 10 years ago.
The Morcombes will help launch a new computer game aimed at preventing child sex abuse after partaking in the Walk For Daniel event on the Sunshine Coast.
The walk follows the path that Daniel followed to a bus stop from where he was abducted and murdered in December 2003.
Determined to stop other children from suffering the same tragic fate, Bruce and Denise have dedicated their lives to increasing awareness about child safety.

There is no doubt their message is getting through.
During a recent school visit, for instance, the Morcombes saw a girl walk out of class as they spoke about child safety.
"The principal came up to us afterwards and said that the girl disclosed a situation of abuse to them," Denise told AAP.
An earlier presentation at a school in North Queensland prompted a young girl to let someone know about inappropriate photos being sent to her Facebook account.
"She reported it to the teacher," Denise said.
On this year's Day for Daniel, the Morcombes' objective is no different.
"The message we want out there is that we want people to report it," Denise said.
She says Day for Daniel, now in its ninth year, is growing with more walks held across Australia each year.
It's just one of many initiatives of the Daniel Morcombe Foundation.
Then there's a computer game called Orbit, which aims to prevent child sexual abuse.
Bruce said the foundation unreservedly supported the adoption of the Orbit program into every primary school in Australia.
"Engaging children in an online game to appreciate their personal safety is the way forward," he said.
